+
+Number
+
+ EGL Extension #not assigned
+
+Dependencies
+
+ Reguires EGL 1.4 or later. This extension is written against the
+ wording of the EGL 1.4 specification.
+
+ EGL_KHR_base_image is required.
+
+Overview
+
+ This extension provides entry points for integrating EGLImage with the
+ Linux DRM mode setting and memory management drivers. The extension
+ lets applications create EGLImages without a client API resource and
+ lets the application get the DRM buffer handles.
+
+IP Status
+
+ Open-source; freely implementable.
+
+New Procedures and Functions
+
+ EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
+ const EGLint *attrib_list);
+
+ EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
+ EGLImageKHR image,
+ EGLint *name,
+ EGLint *handle,
+ EGLint *stride);
+
+New Tokens
+
+ Accepted in the <attrib_list> parameter of eglCreateDRMImageMESA:
+
+ EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
+ EGL_DRM_BUFFER_USE_MESA 0x31D1
+
+ Accepted as values for the EGL_IMAGE_FORMAT_MESA attribute:
+
+ EGL_DRM_BUFFER_FORMAT_ARGB32_MESA 0x31D2
+
+ Bits accepted in EGL_DRM_BUFFER_USE_MESA:
+
+ EGL_DRM_BUFFER_USE_SCANOUT_MESA 0x0001
+ EGL_DRM_BUFFER_USE_SHARE_MESA 0x0002
+
+ Accepted in the <target> parameter of eglCreateImageKHR:
+
+ EGL_DRM_BUFFER_MESA 0x31D3
+
+ Use when importing drm buffer:
+
+ EGL_DRM_BUFFER_STRIDE_MESA 0x31D4
+ EGL_DRM_BUFFER_FORMAT_MESA 0x31D0
+
+Additions to the EGL 1.4 Specification:
+
+ To create a DRM EGLImage, call
+
+ EGLImageKHR eglCreateDRMImageMESA(EGLDisplay dpy,
+ const EGLint *attrib_list);
+
+ In the attribute list, pass EGL_WIDTH, EGL_EIGHT and format and
+ use in the attrib list using EGL_DRM_BUFFER_FORMAT_MESA and
+ EGL_DRM_BUFFER_USE_MESA. The only format specified by this
+ extension is EGL_DRM_BUFFER_FORMAT_ARGB32_MESA, where each pixel
+ is a CPU-endian, 32-bit quantity, with alpha in the upper 8 bits,
+ then red, then green, then blue. The bit values accepted by
+ EGL_DRM_BUFFER_USE_MESA are EGL_DRM_BUFFER_USE_SCANOUT_MESA and
+ EGL_DRM_BUFFER_USE_SHARE_MESA. EGL_DRM_BUFFER_USE_SCANOUT_MESA
+ requests that the created EGLImage should be usable as a scanout
+ buffer with the DRM kernel modesetting API. The
+ EGL_DRM_BUFFER_USE_SHARE_MESA bit requests that the EGLImage can
+ be shared with other processes by passing the underlying DRM
+ buffer name.
+
+ To create a process local handle or a global DRM name for a
+ buffer, call
+
+ EGLBoolean eglExportDRMImageMESA(EGLDisplay dpy,
+ EGLImageKHR image,
+ EGLint *name,
+ EGLint *handle,
+ EGLint *stride);
+
+ If <name> is non-NULL, a global name is assigned to the image and
+ written to <name>, the handle (local to the DRM file descriptor,
+ for use with DRM kernel modesetting API) is written to <handle> if
+ non-NULL and the stride (in bytes) is written to <stride>, if
+ non-NULL.
+
+ Import a shared buffer by calling eglCreateImageKHR with
+ EGL_DRM_BUFFER_MESA as the target, using EGL_WIDTH, EGL_HEIGHT,
+ EGL_DRM_BUFFER_FORMAT_MESA, EGL_DRM_BUFFER_STRIDE_MESA
+ in the attrib list.
+
+Issues
+
+ 1. Why don't we use eglCreateImageKHR with a target that
+ indicates that we want to create an EGLImage from scratch?
+
+ RESOLVED: The eglCreateImageKHR entry point is reserved for
+ creating an EGLImage from an already existing client API
+ resource. This is fine when we're creating the EGLImage from
+ an existing DRM buffer name, it doesn't seem right to overload
+ the function to also allocate the underlying resource.
+
+ 2. Why don't we use an eglQueryImageMESA type functions for
+ querying the DRM EGLImage attributes (name, handle, and stride)?
+
+ RESOLVED: The eglQueryImage function has been proposed often,
+ but it goes against the EGLImage design. EGLImages are opaque
+ handles to a 2D array of pixels, which can be passed between
+ client APIs. By referenceing an EGLImage in a client API, the
+ EGLImage target (a texture, a renderbuffer or such) can be
+ used to query the attributes of the EGLImage. We don't have a
+ full client API for creating and querying DRM buffers, though,
+ so we use a new EGL extension entry point instead.
+
+Revision History
+
+ Version 1, June 3, 2010
+ Initial draft (Kristian Høgsberg)
+ Version 2, August 25, 2010
+ Flesh out the extension a bit, add final EGL tokens, capture
+ some of the original discussion in the issues section.

<ul>
-<li>Declare <em>in</em> function parameters as <em>const</em> whenever possible.
- This improves the efficiency of function inlining.
-</li>
-<br>
-<li>To reduce register usage, declare variables within smaller scopes.
- For example, the following code:
-<pre>
- void main()
- {
- vec4 a1, a2, b1, b2;
- gl_Position = expression using a1, a2.
- gl_Color = expression using b1, b2;
- }
-</pre>
- Can be rewritten as follows to use half as many registers:
-<pre>
- void main()
- {
- {
- vec4 a1, a2;
- gl_Position = expression using a1, a2.
- }
- {
- vec4 b1, b2;
- gl_Color = expression using b1, b2;
- }
- }
-</pre>
- Alternately, rather than using several float variables, use
- a vec4 instead. Use swizzling and writemasks to access the
- components of the vec4 as floats.
-</li>
-<br>
<li>Use the built-in library functions whenever possible.
For example, instead of writing this:
<pre>
<pre>
float x = inversesqrt(y);
</pre>
-<li>
- Use ++i when possible as it's more efficient than i++
</li>
</ul>
<h2>Stand-alone GLSL Compiler</h2>
<p>
-A unique stand-alone GLSL compiler driver has been added to Mesa.
-<p>
-
-<p>
-The stand-alone compiler (like a conventional command-line compiler)
-is a tool that accepts Shading Language programs and emits low-level
-GPU programs.
+The stand-alone GLSL compiler program can be used to compile GLSL shaders
+into low-level GPU code.
</p>
<p>
</ul>
<p>
-After building Mesa, the glslcompiler can be built by manually running:
+After building Mesa, the compiler can be found at src/glsl/glsl_compiler
</p>
-<pre>
- make realclean
- make linux
- cd src/mesa/drivers/glslcompiler
- make
-</pre>
-
<p>
Here's an example of using the compiler to compile a vertex shader and
emit GL_ARB_vertex_program-style instructions:
</p>
<pre>
- bin/glslcompiler --debug --numbers --fs progs/glsl/CH06-brick.frag.txt
-</pre>
-<p>
-results in:
-</p>
-<pre>
-# Fragment Program/Shader
- 0: RCP TEMP[4].x, UNIFORM[2].xxxx;
- 1: RCP TEMP[4].y, UNIFORM[2].yyyy;
- 2: MUL TEMP[3].xy, VARYING[0], TEMP[4];
- 3: MOV TEMP[1], TEMP[3];
- 4: MUL TEMP[0].w, TEMP[1].yyyy, CONST[4].xxxx;
- 5: FRC TEMP[1].z, TEMP[0].wwww;
- 6: SGT.C TEMP[0].w, TEMP[1].zzzz, CONST[4].xxxx;
- 7: IF (NE.wwww); # (if false, goto 9);
- 8: ADD TEMP[1].x, TEMP[1].xxxx, CONST[4].xxxx;
- 9: ENDIF;
- 10: FRC TEMP[1].xy, TEMP[1];
- 11: SGT TEMP[2].xy, UNIFORM[3], TEMP[1];
- 12: MUL TEMP[1].z, TEMP[2].xxxx, TEMP[2].yyyy;
- 13: LRP TEMP[0], TEMP[1].zzzz, UNIFORM[0], UNIFORM[1];
- 14: MUL TEMP[0].xyz, TEMP[0], VARYING[1].xxxx;
- 15: MOV OUTPUT[0].xyz, TEMP[0];
- 16: MOV OUTPUT[0].w, CONST[4].yyyy;
- 17: END
+ src/glsl/glslcompiler --dump-ast myshader.vert
</pre>
-<p>
-Note that some shading language constructs (such as uniform and varying
-variables) aren't expressible in ARB or NV-style programs.
-Therefore, the resulting output is not always legal by definition of
-those program languages.
-</p>
-<p>
-Also note that this compiler driver is still under development.
-Over time, the correctness of the GPU programs, with respect to the ARB
-and NV languagues, should improve.
-</p>
+Options include
+<ul>
+<li><b>--dump-ast</b> - dump GPU code
+<li><b>--dump-hir</b> - dump high-level IR code
+<li><b>--dump-lir</b> - dump low-level IR code
+<li><b>--link</b> - ???
+</ul>
+
<p>
The source code for Mesa's shading language compiler is in the
-<code>src/mesa/shader/slang/</code> directory.
+<code>src/glsl/</code> directory.
</p>
<p>
-The compiler follows a fairly standard design and basically works as follows:
+XXX provide some info about the compiler....
</p>
-<ul>
-<li>The input string is tokenized (see grammar.c) and parsed
-(see slang_compiler_*.c) to produce an Abstract Syntax Tree (AST).
-The nodes in this tree are slang_operation structures
-(see slang_compile_operation.h).
-The nodes are decorated with symbol table, scoping and datatype information.
-<li>The AST is converted into an Intermediate representation (IR) tree
-(see the slang_codegen.c file).
-The IR nodes represent basic GPU instructions, like add, dot product,
-move, etc.
-The IR tree is mostly a binary tree, but a few nodes have three or four
-children.
-In principle, the IR tree could be executed by doing an in-order traversal.
-<li>The IR tree is traversed in-order to emit code (see slang_emit.c).
-This is also when registers are allocated to store variables and temps.
-<li>In the future, a pattern-matching code generator-generator may be
-used for code generation.
-Programs such as L-BURG (Bottom-Up Rewrite Generator) and Twig look for
-patterns in IR trees, compute weights for subtrees and use the weights
-to select the best instructions to represent the sub-tree.
-<li>The emitted GPU instructions (see prog_instruction.h) are stored in a
-gl_program object (see mtypes.h).
-<li>When a fragment shader and vertex shader are linked (see slang_link.c)
-the varying vars are matched up, uniforms are merged, and vertex
-attributes are resolved (rewriting instructions as needed).
-</ul>
<p>
The final vertex and fragment programs may be interpreted in software
<h2>Compiler Validation</h2>
<p>
-A <a href="http://glean.sf.net" target="_parent">Glean</a> test has
-been create to exercise the GLSL compiler.
-</p>
-<p>
-The <em>glsl1</em> test runs over 170 sub-tests to check that the language
-features and built-in functions work properly.
-This test should be run frequently while working on the compiler to catch
+Developers working on the GLSL compiler should test frequently to avoid
regressions.
</p>
+
<p>
-The test coverage is reasonably broad and complete but additional tests
-should be added.
+The <a href="http://people.freedesktop.org/~nh/piglit/">Piglit</a> project
+has many GLSL tests and the
+<a href="http://glean.sf.net" target="_parent">Glean</a> glsl1 test
+tests GLSL features.
</p>
+<p>
+The Mesa demos repository also has some good GLSL tests.

+Resources and derived objects
+=============================
+
+Resources represent objects that hold data: textures and buffers.
+
+They are mostly modelled after the resources in Direct3D 10/11, but with a
+different transfer/update mechanism, and more features for OpenGL support.
+
+Resources can be used in several ways, and it is required to specify all planned uses through an appropriate set of bind flags.
+
+TODO: write much more on resources
+
+Transfers
+---------
+
+Transfers are the mechanism used to access resources with the CPU.
+
+OpenGL: OpenGL supports mapping buffers and has inline transfer functions for both buffers and textures
+
+D3D11: D3D11 lacks transfers, but has special resource types that are mappable to the CPU address space
+
+TODO: write much more on transfers
+
+Resource targets
+----------------
+
+Resource targets determine the type of a resource.
+
+Note that drivers may not actually have the restrictions listed regarding
+coordinate normalization and wrap modes, and in fact efficient OpenCL
+support will probably require drivers that don't have any of them, which
+will probably be advertised with an appropriate cap.
+
+TODO: document all targets. Note that both 3D and cube have restrictions
+that depend on the hardware generation.
+
+TODO: can buffers have a non-R8 format?
+
+PIPE_BUFFER
+^^^^^^^^^^^
+
+Buffer resource: can be used as a vertex, index, constant buffer (appropriate bind flags must be requested).
+
+They can be bound to stream output if supported.
+TODO: what about the restrictions lifted by the several later GL transform feedback extensions? How does one advertise that in Gallium?
+
+They can be also be bound to a shader stage as usual.
+TODO: are all drivers supposed to support this? how does this work exactly? are there size limits?
+
+They can be also be bound to the framebuffer as usual.
+TODO: are all drivers supposed to support this? how does this work exactly? are there size limits?
+TODO: is there any chance of supporting GL pixel buffer object acceleration with this?

+ * 1. The first mipmap level is 64-byte-aligned
+ * PROOF:
+ * 1. Thus, all mipmaps level with a parent which is 64-byte or more in size are.
+ * 2. At 1bpp, the smallest levels with a <= 32-byte parent are either Nx1 or 1xN or size <=8, thus 4x2, 2x2 or 2x4
+ * 3. Nx1, 1xN, 2x4, 2x2 have all subrects linearizable. 4x2 does not.
+ * 4. At 2/4bpp or more, the smallest levels with a 32-byte parent are 1xN, Nx1 or 2x2
+ *
+ * However, nv04_region_align handles that.

+ * As an additional optimization, we record when all the programs have the
+ * current input slot configuration, and at that point we stop patching inputs.
+ * This happens, for instance, if a given fragment program is always used with
+ * the same vertex program (i.e. always with GLSL), or if the layouts match

+Welcome to Mesa's GLSL compiler. A brief overview of how things flow:
+
+1) lex and yacc-based preprocessor takes the incoming shader string
+and produces a new string containing the preprocessed shader. This
+takes care of things like #if, #ifdef, #define, and preprocessor macro
+invocations. Note that #version, #extension, and some others are
+passed straight through. See glcpp/*
+
+2) lex and yacc-based parser takes the preprocessed string and
+generates the AST (abstract syntax tree). Almost no checking is
+performed in this stage. See glsl_lexer.lpp and glsl_parser.ypp.
+
+3) The AST is converted to "HIR". This is the intermediate
+representation of the compiler. Constructors are generated, function
+calls are resolved to particular function signatures, and all the
+semantic checking is performed. See ast_*.cpp for the conversion, and
+ir.h for the IR structures.
+
+4) The driver (Mesa, or main.cpp for the standalone binary) performs
+optimizations. These include copy propagation, dead code elimination,
+constant folding, and others. Generally the driver will call
+optimizations in a loop, as each may open up opportunities for other
+optimizations to do additional work. See most files called ir_*.cpp
+
+5) linking is performed. This does checking to ensure that the
+outputs of the vertex shader match the inputs of the fragment shader,
+and assigns locations to uniforms, attributes, and varyings. See
+linker.cpp.
+
+6) The driver may perform additional optimization at this point, as
+for example dead code elimination previously couldn't remove functions
+or global variable usage when we didn't know what other code would be
+linked in.
+
+7) The driver performs code generation out of the IR, taking a linked
+shader program and producing a compiled program for each stage. See
+ir_to_mesa.cpp for Mesa IR code generation.
+
+FAQ:
+
+Q: What is HIR versus IR versus LIR?
+
+A: The idea behind the naming was that ast_to_hir would produce a
+high-level IR ("HIR"), with things like matrix operations, structure
+assignments, etc., present. A series of lowering passes would occur
+that do things like break matrix multiplication into a series of dot
+products/MADs, make structure assignment be a series of assignment of
+components, flatten if statements into conditional moves, and such,
+producing a low level IR ("LIR").
+
+However, it now appears that each driver will have different
+requirements from a LIR. A 915-generation chipset wants all functions
+inlined, all loops unrolled, all ifs flattened, no variable array
+accesses, and matrix multiplication broken down. The Mesa IR backend
+for swrast would like matrices and structure assignment broken down,
+but it can support function calls and dynamic branching. A 965 vertex
+shader IR backend could potentially even handle some matrix operations
+without breaking them down, but the 965 fragment shader IR backend
+would want to break to have (almost) all operations down channel-wise
+and perform optimization on that. As a result, there's no single
+low-level IR that will make everyone happy. So that usage has fallen
+out of favor, and each driver will perform a series of lowering passes
+to take the HIR down to whatever restrictions it wants to impose
+before doing codegen.
+
+Q: How is the IR structured?
+
+A: The best way to get started seeing it would be to run the
+standalone compiler against a shader:
+
+./glsl_compiler --dump-lir \
+ ~/src/piglit/tests/shaders/glsl-orangebook-ch06-bump.frag
+
+So for example one of the ir_instructions in main() contains:
+
+(assign (constant bool (1)) (var_ref litColor) (expression vec3 * (var_ref Surf
+aceColor) (var_ref __retval) ) )
+
+Or more visually:
+ (assign)
+ / | \
+ (var_ref) (expression *) (constant bool 1)
+ / / \
+(litColor) (var_ref) (var_ref)
+ / \
+ (SurfaceColor) (__retval)
+
+which came from:
+
+litColor = SurfaceColor * max(dot(normDelta, LightDir), 0.0);
+
+(the max call is not represented in this expression tree, as it was a
+function call that got inlined but not brought into this expression
+tree)
+
+Each of those nodes is a subclass of ir_instruction. A particular
+ir_instruction instance may only appear once in the whole IR tree with
+the exception of ir_variables, which appear once as variable
+declarations:
+
+(declare () vec3 normDelta)
+
+and multiple times as the targets of variable dereferences:
+...
+(assign (constant bool (1)) (var_ref __retval) (expression float dot
+ (var_ref normDelta) (var_ref LightDir) ) )
+...
+(assign (constant bool (1)) (var_ref __retval) (expression vec3 -
+ (var_ref LightDir) (expression vec3 * (constant float (2.000000))
+ (expression vec3 * (expression float dot (var_ref normDelta) (var_ref
+ LightDir) ) (var_ref normDelta) ) ) ) )
+...
+
+Each node has a type. Expressions may involve several different types:
+(declare (uniform ) mat4 gl_ModelViewMatrix)
+((assign (constant bool (1)) (var_ref constructor_tmp) (expression
+ vec4 * (var_ref gl_ModelViewMatrix) (var_ref gl_Vertex) ) )
+
+An expression tree can be arbitrarily deep, and the compiler tries to
+keep them structured like that so that things like algebraic
+optimizations ((color * 1.0 == color) and ((mat1 * mat2) * vec == mat1
+* (mat2 * vec))) or recognizing operation patterns for code generation
+(vec1 * vec2 + vec3 == mad(vec1, vec2, vec3)) are easier. This comes
+at the expense of additional trickery in implementing some
+optimizations like CSE where one must navigate an expression tree.
+
+Q: Why no SSA representation?
+
+A: Converting an IR tree to SSA form makes dead code elmimination,
+common subexpression elimination, and many other optimizations much
+easier. However, in our primarily vector-based language, there's some
+major questions as to how it would work. Do we do SSA on the scalar
+or vector level? If we do it at the vector level, we're going to end
+up with many different versions of the variable when encountering code
+like:
+
+(assign (constant bool (1)) (swiz x (var_ref __retval) ) (var_ref a) )
+(assign (constant bool (1)) (swiz y (var_ref __retval) ) (var_ref b) )
+(assign (constant bool (1)) (swiz z (var_ref __retval) ) (var_ref c) )
+
+If every masked update of a component relies on the previous value of
+the variable, then we're probably going to be quite limited in our
+dead code elimination wins, and recognizing common expressions may
+just not happen. On the other hand, if we operate channel-wise, then
+we'll be prone to optimizing the operation on one of the channels at
+the expense of making its instruction flow different from the other
+channels, and a vector-based GPU would end up with worse code than if
+we didn't optimize operations on that channel!
+
+Once again, it appears that our optimization requirements are driven
+significantly by the target architecture. For now, targeting the Mesa
+IR backend, SSA does not appear to be that important to producing
+excellent code, but we do expect to do some SSA-based optimizations
+for the 965 fragment shader backend when that is developed.
+
+Q: How should I expand instructions that take multiple backend instructions?
+
+Sometimes you'll have to do the expansion in your code generation --
+see, for example, ir_to_mesa.cpp's handling of ir_binop_mul for
+matrices. However, in many cases you'll want to do a pass over the IR
+to convert non-native instructions to a series of native instructions.
+For example, for the Mesa backend we have ir_div_to_mul_rcp.cpp because
+Mesa IR (and many hardware backends) only have a reciprocal
+instruction, not a divide. Implementing non-native instructions this
+way gives the chance for constant folding to occur, so (a / 2.0)
+becomes (a * 0.5) after codegen instead of (a * (1.0 / 2.0))
+
+Q: How shoud I handle my special hardware instructions with respect to IR?
+
+Our current theory is that if multiple targets have an instruction for
+some operation, then we should probably be able to represent that in
+the IR. Generally this is in the form of an ir_{bin,un}op expression
+type. For example, we initially implemented fract() using (a -
+floor(a)), but both 945 and 965 have instructions to give that result,
+and it would also simplify the implementation of mod(), so
+ir_unop_fract was added. The following areas need updating to add a
+new expression type:
+
+ir.h (new enum)
+ir.cpp:get_num_operands() (used for ir_reader)
+ir.cpp:operator_strs (used for ir_reader)
+ir_constant_expression.cpp (you probably want to be able to constant fold)
+ir_validate.cpp (check users have the right types)
+
+You may also need to update the backends if they will see the new expr type:
+
+../mesa/shaders/ir_to_mesa.cpp
+
+You can then use the new expression from builtins (if all backends
+would rather see it), or scan the IR and convert to use your new
+expression type (see ir_mod_to_fract, for example).

+ * code was not committed, merge conflicts where created because two developers
+ * had slightly different versions of Bison installed, etc.
+ *
+ * I have also noticed that running Bison generated parsers in GDB is very
+ * irritating. When you get a segfault on '$$ = $1->foo', you can't very

+glcpp -- GLSL "C" preprocessor
+
+This is a simple preprocessor designed to provide the preprocessing
+needs of the GLSL language. The requirements for this preprocessor are
+specified in the GLSL 1.30 specification availble from:
+
+http://www.opengl.org/registry/doc/GLSLangSpec.Full.1.30.10.pdf
+
+This specification is not precise on some semantics, (for example,
+#define and #if), defining these merely "as is standard for C++
+preprocessors". To fill in these details, I've been using a draft of
+the C99 standard as available from:
+
+http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1256.pdf
+
+Any downstream compiler accepting output from glcpp should be prepared
+to encounter and deal with the following preprocessor macros:
+
+ #line
+ #pragma
+ #extension
+
+All other macros will be handles according to the GLSL specification
+and will not appear in the output.
+
+Known limitations
+-----------------
+The __LINE__ and __FILE__ macros are not yet supported.
+
+A file that ends with a function-like macro name as the last
+non-whitespace token will result in a parse error, (where it should be
+passed through as is).

+ * Base class of hierarchical visitors of IR instruction trees
+ *
+ * Hierarchical visitors differ from traditional visitors in a couple of
+ * important ways. Rather than having a single \c visit method for each
+ * subclass in the composite, there are three kinds of visit methods.
+ * Leaf-node classes have a traditional \c visit method. Internal-node
+ * classes have a \c visit_enter method, which is invoked just before
+ * processing child nodes, and a \c visit_leave method which is invoked just
+ * after processing child nodes.
+ *
+ * In addition, each visit method and the \c accept methods in the composite
+ * have a return value which guides the navigation. Any of the visit methods
+ * can choose to continue visiting the tree as normal (by returning \c
+ * visit_continue), terminate visiting any further nodes immediately (by
+ * returning \c visit_stop), or stop visiting sibling nodes (by returning \c
+ * visit_continue_with_parent).
+ *
+ * These two changes combine to allow nagivation of children to be implemented
+ * in the composite's \c accept method. The \c accept method for a leaf-node
+ * class will simply call the \c visit method, as usual, and pass its return
+ * value on. The \c accept method for internal-node classes will call the \c
+ * visit_enter method, call the \c accpet method of each child node, and,
+ * finally, call the \c visit_leave method. If any of these return a value
+ * other that \c visit_continue, the correct action must be taken.
+ *
+ * The final benefit is that the hierarchical visitor base class need not be
+ * abstract. Default implementations of every \c visit, \c visit_enter, and
+ * \c visit_leave method can be provided. By default each of these methods
+ * simply returns \c visit_continue. This allows a significant reduction in
+ * derived class code.
+ *
+ * For more information about hierarchical visitors, see:
+ *
+ * http://c2.com/cgi/wiki?HierarchicalVisitorPattern

+/**
+ * \file linker.cpp
+ * GLSL linker implementation
+ *
+ * Given a set of shaders that are to be linked to generate a final program,
+ * there are three distinct stages.
+ *
+ * In the first stage shaders are partitioned into groups based on the shader
+ * type. All shaders of a particular type (e.g., vertex shaders) are linked
+ * together.
+ *
+ * - Undefined references in each shader are resolve to definitions in
+ * another shader.
+ * - Types and qualifiers of uniforms, outputs, and global variables defined
+ * in multiple shaders with the same name are verified to be the same.
+ * - Initializers for uniforms and global variables defined
+ * in multiple shaders with the same name are verified to be the same.
+ *
+ * The result, in the terminology of the GLSL spec, is a set of shader
+ * executables for each processing unit.
+ *
+ * After the first stage is complete, a series of semantic checks are performed
+ * on each of the shader executables.
+ *
+ * - Each shader executable must define a \c main function.
+ * - Each vertex shader executable must write to \c gl_Position.
+ * - Each fragment shader executable must write to either \c gl_FragData or
+ * \c gl_FragColor.
+ *
+ * In the final stage individual shader executables are linked to create a
+ * complete exectuable.
+ *
+ * - Types of uniforms defined in multiple shader stages with the same name
+ * are verified to be the same.
+ * - Initializers for uniforms defined in multiple shader stages with the
+ * same name are verified to be the same.
+ * - Types and qualifiers of outputs defined in one stage are verified to
+ * be the same as the types and qualifiers of inputs defined with the same
+ * name in a later stage.

+/**
+ * \file list.h
+ * \brief Doubly-linked list abstract container type.
+ *
+ * Each doubly-linked list has a sentinel head and tail node. These nodes
+ * contain no data. The head sentinel can be identified by its \c prev
+ * pointer being \c NULL. The tail sentinel can be identified by its
+ * \c next pointer being \c NULL.
+ *
+ * A list is empty if either the head sentinel's \c next pointer points to the
+ * tail sentinel or the tail sentinel's \c prev poiner points to the head
+ * sentinel.
+ *
+ * Instead of tracking two separate \c node structures and a \c list structure
+ * that points to them, the sentinel nodes are in a single structure. Noting
+ * that each sentinel node always has one \c NULL pointer, the \c NULL
+ * pointers occupy the same memory location. In the \c list structure
+ * contains a the following:
+ *
+ * - A \c head pointer that represents the \c next pointer of the
+ * head sentinel node.
+ * - A \c tail pointer that represents the \c prev pointer of the head
+ * sentinel node and the \c next pointer of the tail sentinel node. This
+ * pointer is \b always \c NULL.
+ * - A \c tail_prev pointer that represents the \c prev pointer of the
+ * tail sentinel node.
+ *
+ * Therefore, if \c head->next is \c NULL or \c tail_prev->prev is \c NULL,
+ * the list is empty.
+ *
+ * To anyone familiar with "exec lists" on the Amiga, this structure should
+ * be immediately recognizable. See the following link for the original Amiga
+ * operating system documentation on the subject.
+ *
+ * http://www.natami.net/dev/Libraries_Manual_guide/node02D7.html

+ * Breaks vector operations down into operations on each component.
+ *
+ * The 965 fragment shader receives 8 or 16 pixels at a time, so each
+ * channel of a vector is laid out as 1 or 2 8-float registers. Each
+ * ALU operation operates on one of those channel registers. As a
+ * result, there is no value to the 965 fragment shader in tracking
+ * "vector" expressions in the sense of GLSL fragment shaders, when
+ * doing a channel at a time may help in constant folding, algebraic
+ * simplification, and reducing the liveness of channel registers.
+ *
+ * The exception to the desire to break everything down to floats is
+ * texturing. The texture sampler returns a writemasked masked
+ * 4/8-register sequence containing the texture values. We don't want
+ * to dispatch to the sampler separately for each channel we need, so
+ * we do retain the vector types in that case.

-/**
- * \mainpage
- *
- * Stand-alone Shading Language compiler.
- * Basically, a command-line program which accepts GLSL shaders and emits
- * vertex/fragment programs (GPU instructions).
- *
- * This file is basically just a Mesa device driver but instead of building
- * a shared library we build an executable.
- *
- * We can emit programs in three different formats:
- * 1. ARB-style (GL_ARB_vertex/fragment_program)
- * 2. NV-style (GL_NV_vertex/fragment_program)
- * 3. debug-style (a slightly more sophisticated, internal format)
- *
- * Note that the ARB and NV program languages can't express all the
- * features that might be used by a fragment program (examples being
- * uniform and varying vars). So, the ARB/NV programs that are
- * emitted aren't always legal programs in those languages.

-// Constructors and operators introduced in GLSL 1.20 - mostly on new
-// (non-square) types of matrices.
-//
-// One important change in the language is that when a matrix is used
-// as an argument to a matrix constructor, it must be the only argument
-// for the constructor. The compiler takes care of it by itself and
-// here we only care to re-introduce constructors for old (square)
-// types of matrices.

-//
-// This file defines nearly all constructors and operators for built-in data
-// types, using extended language syntax. In general, compiler treats
-// constructors and operators as ordinary functions with some exceptions.
-// For example, the language does not allow functions to be called in
-// constant expressions - here the exception is made to allow it.
-//
-// Each implementation provides its own version of this file. Each
-// implementation can define the required set of operators and constructors
-// in its own fashion.
-//
-// The extended language syntax is only present when compiling this file.
-// It is implicitly included at the very beginning of the compiled shader,
-// so no built-in functions can be used.
-//
-// To communicate with the implementation, a special extended "__asm" keyword
-// is used, followed by an instruction name (any valid identifier), a
-// destination variable identifier and a list of zero or more source
-// variable identifiers.
-//
-// A variable identifier is a variable name declared earlier in the code
-// (as a function parameter, local or global variable).
-//
-// An instruction name designates an instruction that must be exported
-// by the implementation. Each instruction receives data from source
-// variable identifiers and returns data in the destination variable
-// identifier.
-//
-// It is up to the implementation how to define a particular operator
-// or constructor. If it is expected to being used rarely, it can be
-// defined in terms of other operators and constructors,
-// for example:
-//
-// ivec2 __operator + (const ivec2 x, const ivec2 y) {
-// return ivec2 (x[0] + y[0], x[1] + y[1]);
-// }
-//
-// If a particular operator or constructor is expected to be used very
-// often or is an atomic operation (that is, an operation that cannot be
-// expressed in terms of other operations or would create a dependency
-// cycle) it must be defined using one or more __asm constructs.
-//
-// Each implementation must define constructors for all scalar types
-// (bool, float, int). There are 9 scalar-to-scalar constructors
-// (including identity constructors). However, since the language
-// introduces special constructors (like matrix constructor with a single
-// scalar value), implementations must also implement these cases.
-// The compiler provides the following algorithm when resolving a constructor:
-// - try to find a constructor with a prototype matching ours,
-// - if no constructor is found and this is a scalar-to-scalar constructor,
-// raise an error,
-// - if a constructor is found, execute it and return,
-// - count the size of the constructor parameter list - if it is less than
-// the size of our constructor's type, raise an error,
-// - for each parameter in the list do a recursive constructor matching for
-// appropriate scalar fields in the constructed variable,
-//
-// Each implementation must also define a set of operators that deal with
-// built-in data types.
-// There are four kinds of operators:
-// 1) Operators that are implemented only by the compiler: "()" (function
-// call), "," (sequence) and "?:" (selection).
-// 2) Operators that are implemented by the compiler by expressing it in
-// terms of other operators:
-// - "." (field selection) - translated to subscript access,
-// - "&&" (logical and) - translated to "<left_expr> ? <right_expr> :
-// false",
-// - "||" (logical or) - translated to "<left_expr> ? true : <right_expr>",
-// 3) Operators that can be defined by the implementation and if the required
-// prototype is not found, standard behaviour is used:
-// - "==", "!=", "=" (equality, assignment) - compare or assign
-// matching fields one-by-one;
-// note that at least operators for scalar data types must be defined
-// by the implementation to get it work,
-// 4) All other operators not mentioned above. If no required prototype is
-// found, an error is raised. An implementation must follow the language
-// specification to provide all valid operator prototypes.

- * Describes where data/variables are stored in the various register files.
- *
- * In the simple case, the File, Index and Size fields indicate where
- * a variable is stored. For example, a vec3 variable may be stored
- * as (File=PROGRAM_TEMPORARY, Index=6, Size=3). Or, File[Index].
- * Or, a program input like color may be stored as
- * (File=PROGRAM_INPUT,Index=3,Size=4);
- *
- * For single-float values, the Swizzle field indicates which component
- * of the vector contains the float.
- *
- * If IsIndirect is set, the storage is accessed through an indirect
- * register lookup. The value in question will be located at:
- * File[Index + IndirectFile[IndirectIndex]]
- *
- * This is primary used for indexing arrays. For example, consider this
- * GLSL code:
- * uniform int i;
- * float a[10];
- * float x = a[i];
- *
- * here, storage for a[i] would be described by (File=PROGRAM_TEMPORAY,
- * Index=aPos, IndirectFile=PROGRAM_UNIFORM, IndirectIndex=iPos), which
- * would mean TEMP[aPos + UNIFORM[iPos]]

+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+ To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights. Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received. You must make sure that they, too, receive
+or can get the source code. And you must show them these terms so they
+know their rights.
+
+ Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+ For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software. For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+ Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so. This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software. The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable. Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products. If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+ Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary. To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ TERMS AND CONDITIONS
+
+ 0. Definitions.
+
+ "This License" refers to version 3 of the GNU General Public License.
+
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+ "The Program" refers to any copyrightable work licensed under this
+License. Each licensee is addressed as "you". "Licensees" and
+"recipients" may be individuals or organizations.
+
+ To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy. The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+ A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+ To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy. Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+ To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies. Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+ An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License. If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+ 1. Source Code.
+
+ The "source code" for a work means the preferred form of the work
+for making modifications to it. "Object code" means any non-source
+form of a work.
+
+ A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+ The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form. A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+ The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities. However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work. For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+ The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+ The Corresponding Source for a work in source code form is that
+same work.
+
+ 2. Basic Permissions.
+
+ All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met. This License explicitly affirms your unlimited
+permission to run the unmodified Program. The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work. This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+ You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force. You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright. Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+ Conveying under any other circumstances is permitted solely under
+the conditions stated below. Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+ No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+ When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+ 4. Conveying Verbatim Copies.
+
+ You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+ You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+ 5. Conveying Modified Source Versions.
+
+ You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+ a) The work must carry prominent notices stating that you modified
+ it, and giving a relevant date.
+
+ b) The work must carry prominent notices stating that it is
+ released under this License and any conditions added under section
+ 7. This requirement modifies the requirement in section 4 to
+ "keep intact all notices".
+
+ c) You must license the entire work, as a whole, under this
+ License to anyone who comes into possession of a copy. This
+ License will therefore apply, along with any applicable section 7
+ additional terms, to the whole of the work, and all its parts,
+ regardless of how they are packaged. This License gives no
+ permission to license the work in any other way, but it does not
+ invalidate such permission if you have separately received it.
+
+ d) If the work has interactive user interfaces, each must display
+ Appropriate Legal Notices; however, if the Program has interactive
+ interfaces that do not display Appropriate Legal Notices, your
+ work need not make them do so.
+
+ A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit. Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+ 6. Conveying Non-Source Forms.
+
+ You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+ a) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by the
+ Corresponding Source fixed on a durable physical medium
+ customarily used for software interchange.
+
+ b) Convey the object code in, or embodied in, a physical product
+ (including a physical distribution medium), accompanied by a
+ written offer, valid for at least three years and valid for as
+ long as you offer spare parts or customer support for that product
+ model, to give anyone who possesses the object code either (1) a
+ copy of the Corresponding Source for all the software in the
+ product that is covered by this License, on a durable physical
+ medium customarily used for software interchange, for a price no
+ more than your reasonable cost of physically performing this
+ conveying of source, or (2) access to copy the
+ Corresponding Source from a network server at no charge.
+
+ c) Convey individual copies of the object code with a copy of the
+ written offer to provide the Corresponding Source. This
+ alternative is allowed only occasionally and noncommercially, and
+ only if you received the object code with such an offer, in accord
+ with subsection 6b.
+
+ d) Convey the object code by offering access from a designated
+ place (gratis or for a charge), and offer equivalent access to the
+ Corresponding Source in the same way through the same place at no
+ further charge. You need not require recipients to copy the
+ Corresponding Source along with the object code. If the place to
+ copy the object code is a network server, the Corresponding Source
+ may be on a different server (operated by you or a third party)
+ that supports equivalent copying facilities, provided you maintain
+ clear directions next to the object code saying where to find the
+ Corresponding Source. Regardless of what server hosts the
+ Corresponding Source, you remain obligated to ensure that it is
+ available for as long as needed to satisfy these requirements.
+
+ e) Convey the object code using peer-to-peer transmission, provided
+ you inform other peers where the object code and Corresponding
+ Source of the work are being offered to the general public at no
+ charge under subsection 6d.
+
+ A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+ A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling. In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage. For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product. A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+ "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source. The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+ If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information. But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+ The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed. Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+ Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+ 7. Additional Terms.
+
+ "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law. If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+ When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it. (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.) You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+ Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+ a) Disclaiming warranty or limiting liability differently from the
+ terms of sections 15 and 16 of this License; or
+
+ b) Requiring preservation of specified reasonable legal notices or
+ author attributions in that material or in the Appropriate Legal
+ Notices displayed by works containing it; or
+
+ c) Prohibiting misrepresentation of the origin of that material, or
+ requiring that modified versions of such material be marked in
+ reasonable ways as different from the original version; or
+
+ d) Limiting the use for publicity purposes of names of licensors or
+ authors of the material; or
+
+ e) Declining to grant rights under trademark law for use of some
+ trade names, trademarks, or service marks; or
+
+ f) Requiring indemnification of licensors and authors of that
+ material by anyone who conveys the material (or modified versions of
+ it) with contractual assumptions of liability to the recipient, for
+ any liability that these contractual assumptions directly impose on
+ those licensors and authors.
+
+ All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10. If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term. If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+ If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+ Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+ 8. Termination.
+
+ You may not propagate or modify a covered work except as expressly
+provided under this License. Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+ However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+ Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+ Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License. If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+ 9. Acceptance Not Required for Having Copies.
+
+ You are not required to accept this License in order to receive or
+run a copy of the Program. Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance. However,
+nothing other than this License grants you permission to propagate or
+modify any covered work. These actions infringe copyright if you do
+not accept this License. Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+ 10. Automatic Licensing of Downstream Recipients.
+
+ Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License. You are not responsible
+for enforcing compliance by third parties with this License.
+
+ An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations. If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+ You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License. For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+ 11. Patents.
+
+ A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based. The
+work thus licensed is called the contributor's "contributor version".
+
+ A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version. For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+ Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+ In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement). To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+ If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients. "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+ If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+ A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License. You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+ Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+ 12. No Surrender of Others' Freedom.
+
+ If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all. For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+ 13. Use with the GNU Affero General Public License.
+
+ Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work. The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+ 14. Revised Versions of this License.
+
+ The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation. If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+ If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+ Later license versions may give you additional or different
+permissions. However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+ 15. Disclaimer of Warranty.
+
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+ 16. Limitation of Liability.
+
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+ 17. Interpretation of Sections 15 and 16.
+
+ If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software: you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation, either version 3 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License
+ along with this program. If not, see <http://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+ If the program does terminal interaction, make it output a short

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+Using talloc in Samba4
+======================
+
+.. contents::
+
+Andrew Tridgell
+August 2009
+
+The most current version of this document is available at
+ http://samba.org/ftp/unpacked/talloc/talloc_guide.txt
+
+If you are used to the "old" talloc from Samba3 before 3.0.20 then please read
+this carefully, as talloc has changed a lot. With 3.0.20 (or 3.0.14?) the
+Samba4 talloc has been ported back to Samba3, so this guide applies to both.
+
+The new talloc is a hierarchical, reference counted memory pool system
+with destructors. Quite a mouthful really, but not too bad once you
+get used to it.
+
+Perhaps the biggest change from Samba3 is that there is no distinction
+between a "talloc context" and a "talloc pointer". Any pointer
+returned from talloc() is itself a valid talloc context. This means
+you can do this::
+
+ struct foo *X = talloc(mem_ctx, struct foo);
+ X->name = talloc_strdup(X, "foo");
+
+and the pointer X->name would be a "child" of the talloc context "X"
+which is itself a child of mem_ctx. So if you do talloc_free(mem_ctx)
+then it is all destroyed, whereas if you do talloc_free(X) then just X
+and X->name are destroyed, and if you do talloc_free(X->name) then
+just the name element of X is destroyed.
+
+If you think about this, then what this effectively gives you is an
+n-ary tree, where you can free any part of the tree with
+talloc_free().
+
+If you find this confusing, then I suggest you run the testsuite to
+watch talloc in action. You may also like to add your own tests to
+testsuite.c to clarify how some particular situation is handled.
+
+
+Performance
+-----------
+
+All the additional features of talloc() over malloc() do come at a
+price. We have a simple performance test in Samba4 that measures
+talloc() versus malloc() performance, and it seems that talloc() is
+about 4% slower than malloc() on my x86 Debian Linux box. For Samba,
+the great reduction in code complexity that we get by using talloc
+makes this worthwhile, especially as the total overhead of
+talloc/malloc in Samba is already quite small.
+
+
+talloc API
+----------
+
+The following is a complete guide to the talloc API. Read it all at
+least twice.
+
+Multi-threading
+---------------
+
+talloc itself does not deal with threads. It is thread-safe (assuming
+the underlying "malloc" is), as long as each thread uses different
+memory contexts.
+If two threads uses the same context then they need to synchronize in
+order to be safe. In particular:
+- when using talloc_enable_leak_report(), giving directly NULL as a
+parent context implicitly refers to a hidden "null context" global
+variable, so this should not be used in a multi-threaded environment
+without proper synchronization ;
+- the context returned by talloc_autofree_context() is also global so
+shouldn't be used by several threads simultaneously without
+synchronization.
+
+

+(type *)talloc(const void *context, type);
+
+The talloc() macro is the core of the talloc library. It takes a
+memory context and a type, and returns a pointer to a new area of
+memory of the given type.
+
+The returned pointer is itself a talloc context, so you can use it as
+the context argument to more calls to talloc if you wish.
+
+The returned pointer is a "child" of the supplied context. This means
+that if you talloc_free() the context then the new child disappears as
+well. Alternatively you can free just the child.
+
+The context argument to talloc() can be NULL, in which case a new top
+level context is created.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_size(const void *context, size_t size);
+
+The function talloc_size() should be used when you don't have a
+convenient type to pass to talloc(). Unlike talloc(), it is not type
+safe (as it returns a void *), so you are on your own for type checking.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+(typeof(ptr)) talloc_ptrtype(const void *ctx, ptr);
+
+The talloc_ptrtype() macro should be used when you have a pointer and
+want to allocate memory to point at with this pointer. When compiling
+with gcc >= 3 it is typesafe. Note this is a wrapper of talloc_size()
+and talloc_get_name() will return the current location in the source file.
+and not the type.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_free(void *ptr);
+
+The talloc_free() function frees a piece of talloc memory, and all its
+children. You can call talloc_free() on any pointer returned by
+talloc().
+
+The return value of talloc_free() indicates success or failure, with 0
+returned for success and -1 for failure. The only possible failure
+condition is if the pointer had a destructor attached to it and the
+destructor returned -1. See talloc_set_destructor() for details on
+destructors.
+
+If this pointer has an additional parent when talloc_free() is called
+then the memory is not actually released, but instead the most
+recently established parent is destroyed. See talloc_reference() for
+details on establishing additional parents.
+
+For more control on which parent is removed, see talloc_unlink()
+
+talloc_free() operates recursively on its children.
+
+From the 2.0 version of talloc, as a special case, talloc_free() is
+refused on pointers that have more than one parent, as talloc would
+have no way of knowing which parent should be removed. To free a
+pointer that has more than one parent please use talloc_unlink().
+
+To help you find problems in your code caused by this behaviour, if
+you do try and free a pointer with more than one parent then the
+talloc logging function will be called to give output like this:
+
+ ERROR: talloc_free with references at some_dir/source/foo.c:123
+ reference at some_dir/source/other.c:325
+ reference at some_dir/source/third.c:121
+
+Please see the documentation for talloc_set_log_fn() and
+talloc_set_log_stderr() for more information on talloc logging
+functions.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_free_children(void *ptr);
+
+The talloc_free_children() walks along the list of all children of a
+talloc context and talloc_free()s only the children, not the context
+itself.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_reference(const void *context, const void *ptr);
+
+The talloc_reference() function makes "context" an additional parent
+of "ptr".
+
+The return value of talloc_reference() is always the original pointer
+"ptr", unless talloc ran out of memory in creating the reference in
+which case it will return NULL (each additional reference consumes
+around 48 bytes of memory on intel x86 platforms).
+
+If "ptr" is NULL, then the function is a no-op, and simply returns NULL.
+
+After creating a reference you can free it in one of the following
+ways:
+
+ - you can talloc_free() any parent of the original pointer. That
+ will reduce the number of parents of this pointer by 1, and will
+ cause this pointer to be freed if it runs out of parents.
+
+ - you can talloc_free() the pointer itself. That will destroy the
+ most recently established parent to the pointer and leave the
+ pointer as a child of its current parent.
+
+For more control on which parent to remove, see talloc_unlink()
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_unlink(const void *context, const void *ptr);
+
+The talloc_unlink() function removes a specific parent from ptr. The
+context passed must either be a context used in talloc_reference()
+with this pointer, or must be a direct parent of ptr.
+
+Note that if the parent has already been removed using talloc_free()
+then this function will fail and will return -1. Likewise, if "ptr"
+is NULL, then the function will make no modifications and return -1.
+
+Usually you can just use talloc_free() instead of talloc_unlink(), but
+sometimes it is useful to have the additional control on which parent
+is removed.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_set_destructor(const void *ptr, int (*destructor)(void *));
+
+The function talloc_set_destructor() sets the "destructor" for the
+pointer "ptr". A destructor is a function that is called when the
+memory used by a pointer is about to be released. The destructor
+receives the pointer as an argument, and should return 0 for success
+and -1 for failure.
+
+The destructor can do anything it wants to, including freeing other
+pieces of memory. A common use for destructors is to clean up
+operating system resources (such as open file descriptors) contained
+in the structure the destructor is placed on.
+
+You can only place one destructor on a pointer. If you need more than
+one destructor then you can create a zero-length child of the pointer
+and place an additional destructor on that.
+
+To remove a destructor call talloc_set_destructor() with NULL for the
+destructor.
+
+If your destructor attempts to talloc_free() the pointer that it is
+the destructor for then talloc_free() will return -1 and the free will
+be ignored. This would be a pointless operation anyway, as the
+destructor is only called when the memory is just about to go away.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+int talloc_increase_ref_count(const void *ptr);
+
+The talloc_increase_ref_count(ptr) function is exactly equivalent to:
+
+ talloc_reference(NULL, ptr);
+
+You can use either syntax, depending on which you think is clearer in
+your code.
+
+It returns 0 on success and -1 on failure.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+size_t talloc_reference_count(const void *ptr);
+
+Return the number of references to the pointer.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_set_name(const void *ptr, const char *fmt, ...);
+
+Each talloc pointer has a "name". The name is used principally for
+debugging purposes, although it is also possible to set and get the
+name on a pointer in as a way of "marking" pointers in your code.
+
+The main use for names on pointer is for "talloc reports". See
+talloc_report() and talloc_report_full() for details. Also see
+talloc_enable_leak_report() and talloc_enable_leak_report_full().
+
+The talloc_set_name() function allocates memory as a child of the
+pointer. It is logically equivalent to:
+ talloc_set_name_const(ptr, talloc_asprintf(ptr, fmt, ...));
+
+Note that multiple calls to talloc_set_name() will allocate more
+memory without releasing the name. All of the memory is released when
+the ptr is freed using talloc_free().
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_set_name_const(const void *ptr, const char *name);
+
+The function talloc_set_name_const() is just like talloc_set_name(),
+but it takes a string constant, and is much faster. It is extensively
+used by the "auto naming" macros, such as talloc_p().
+
+This function does not allocate any memory. It just copies the
+supplied pointer into the internal representation of the talloc
+ptr. This means you must not pass a name pointer to memory that will
+disappear before the ptr is freed with talloc_free().
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_named(const void *context, size_t size, const char *fmt, ...);
+
+The talloc_named() function creates a named talloc pointer. It is
+equivalent to:
+
+ ptr = talloc_size(context, size);
+ talloc_set_name(ptr, fmt, ....);
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_named_const(const void *context, size_t size, const char *name);
+
+This is equivalent to::
+
+ ptr = talloc_size(context, size);
+ talloc_set_name_const(ptr, name);
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+const char *talloc_get_name(const void *ptr);
+
+This returns the current name for the given talloc pointer. See
+talloc_set_name() for details.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_init(const char *fmt, ...);
+
+This function creates a zero length named talloc context as a top
+level context. It is equivalent to::
+
+ talloc_named(NULL, 0, fmt, ...);
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_new(void *ctx);
+
+This is a utility macro that creates a new memory context hanging
+off an exiting context, automatically naming it "talloc_new: __location__"
+where __location__ is the source line it is called from. It is
+particularly useful for creating a new temporary working context.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+(type *)talloc_realloc(const void *context, void *ptr, type, count);
+
+The talloc_realloc() macro changes the size of a talloc
+pointer. The "count" argument is the number of elements of type "type"
+that you want the resulting pointer to hold.
+
+talloc_realloc() has the following equivalences::
+
+ talloc_realloc(context, NULL, type, 1) ==> talloc(context, type);
+ talloc_realloc(context, NULL, type, N) ==> talloc_array(context, type, N);
+ talloc_realloc(context, ptr, type, 0) ==> talloc_free(ptr);
+
+The "context" argument is only used if "ptr" is NULL, otherwise it is
+ignored.
+
+talloc_realloc() returns the new pointer, or NULL on failure. The call
+will fail either due to a lack of memory, or because the pointer has
+more than one parent (see talloc_reference()).
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_realloc_size(const void *context, void *ptr, size_t size);
+
+the talloc_realloc_size() function is useful when the type is not
+known so the typesafe talloc_realloc() cannot be used.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_steal(const void *new_ctx, const void *ptr);
+
+The talloc_steal() function changes the parent context of a talloc
+pointer. It is typically used when the context that the pointer is
+currently a child of is going to be freed and you wish to keep the
+memory for a longer time.
+
+The talloc_steal() function returns the pointer that you pass it. It
+does not have any failure modes.
+
+NOTE: It is possible to produce loops in the parent/child relationship
+if you are not careful with talloc_steal(). No guarantees are provided
+as to your sanity or the safety of your data if you do this.
+
+talloc_steal (new_ctx, NULL) will return NULL with no sideeffects.
+
+Note that if you try and call talloc_steal() on a pointer that has
+more than one parent then the result is ambiguous. Talloc will choose
+to remove the parent that is currently indicated by talloc_parent()
+and replace it with the chosen parent. You will also get a message
+like this via the talloc logging functions:
+
+ WARNING: talloc_steal with references at some_dir/source/foo.c:123
+ reference at some_dir/source/other.c:325
+ reference at some_dir/source/third.c:121
+
+To unambiguously change the parent of a pointer please see the
+function talloc_reparent(). See the talloc_set_log_fn() documentation
+for more information on talloc logging.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_reparent(const void *old_parent, const void *new_parent, const void *ptr);
+
+The talloc_reparent() function changes the parent context of a talloc
+pointer. It is typically used when the context that the pointer is
+currently a child of is going to be freed and you wish to keep the
+memory for a longer time.
+
+The talloc_reparent() function returns the pointer that you pass it. It
+does not have any failure modes.
+
+The difference between talloc_reparent() and talloc_steal() is that
+talloc_reparent() can specify which parent you wish to change. This is
+useful when a pointer has multiple parents via references.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void *talloc_parent(const void *ptr);
+
+The talloc_parent() function returns the current talloc parent. This
+is usually the pointer under which this memory was originally created,
+but it may have changed due to a talloc_steal() or talloc_reparent()
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+size_t talloc_total_size(const void *ptr);
+
+The talloc_total_size() function returns the total size in bytes used
+by this pointer and all child pointers. Mostly useful for debugging.
+
+Passing NULL is allowed, but it will only give a meaningful result if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+size_t talloc_total_blocks(const void *ptr);
+
+The talloc_total_blocks() function returns the total memory block
+count used by this pointer and all child pointers. Mostly useful for
+debugging.
+
+Passing NULL is allowed, but it will only give a meaningful result if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report_depth_cb(const void *ptr, int depth, int max_depth,
+ void (*callback)(const void *ptr,
+ int depth, int max_depth,
+ int is_ref,
+ void *priv),
+ void *priv);
+
+This provides a more flexible reports than talloc_report(). It
+will recursively call the callback for the entire tree of memory
+referenced by the pointer. References in the tree are passed with
+is_ref = 1 and the pointer that is referenced.
+
+You can pass NULL for the pointer, in which case a report is
+printed for the top level memory context, but only if
+talloc_enable_leak_report() or talloc_enable_leak_report_full()
+has been called.
+
+The recursion is stopped when depth >= max_depth.
+max_depth = -1 means only stop at leaf nodes.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report_depth_file(const void *ptr, int depth, int max_depth, FILE *f);
+
+This provides a more flexible reports than talloc_report(). It
+will let you specify the depth and max_depth.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report(const void *ptr, FILE *f);
+
+The talloc_report() function prints a summary report of all memory
+used by ptr. One line of report is printed for each immediate child of
+ptr, showing the total memory and number of blocks used by that child.
+
+You can pass NULL for the pointer, in which case a report is printed
+for the top level memory context, but only if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_report_full(const void *ptr, FILE *f);
+
+This provides a more detailed report than talloc_report(). It will
+recursively print the ensire tree of memory referenced by the
+pointer. References in the tree are shown by giving the name of the
+pointer that is referenced.
+
+You can pass NULL for the pointer, in which case a report is printed
+for the top level memory context, but only if
+talloc_enable_leak_report() or talloc_enable_leak_report_full() has
+been called.
+
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
+void talloc_enable_leak_report(void);
+
+This enables calling of talloc_report(NULL, stderr) when the program
+exits. In Samba4 this is enabled by using the --leak-report command
+line option.
+
+For it to be useful, this function must be called before any other
+talloc function as it establishes a "null context" that acts as the
+top of the tree. If you don't call this function first then passing
+NULL to talloc_report() or talloc_report_full() won't give you the
+full tree printout.
+
+Here is a typical talloc report:
+
+talloc report on 'null_context' (total 267 bytes in 15 blocks)
+ libcli/auth/spnego_parse.c:55 contains 31 bytes in 2 blocks
+ libcli/auth/spnego_parse.c:55 contains 31 bytes in 2 blocks

+void talloc_enable_leak_report_full(void);
+
+This enables calling of talloc_report_full(NULL, stderr) when the
+program exits. In Samba4 this is enabled by using the
+--leak-report-full command line option.
+
+For it to be useful, this function must be called before any other
+talloc function as it establishes a "null context" that acts as the
+top of the tree. If you don't call this function first then passing
+NULL to talloc_report() or talloc_report_full() won't give you the
+full tree printout.
+
+Here is a typical full report:
+
+full talloc report on 'root' (total 18 bytes in 8 blocks)
+ p1 contains 18 bytes in 7 blocks (ref 0)
+ r1 contains 13 bytes in 2 blocks (ref 0)
+ reference to: p2
+ p2 contains 1 bytes in 1 blocks (ref 1)
+ x3 contains 1 bytes in 1 blocks (ref 0)
+ x2 contains 1 bytes in 1 blocks (ref 0)
+ x1 contains 1 bytes in 1 blocks (ref 0)

+
+The talloc_ptrtype() macro should be used when you have a pointer to an array
+and want to allocate memory of an array to point at with this pointer. When compiling
+with gcc >= 3 it is typesafe. Note this is a wrapper of talloc_array_size()
+and talloc_get_name() will return the current location in the source file.

+as libraries sometimes want a ralloc function pointer. A realloc()
+implementation encapsulates the functionality of malloc(), free() and
+realloc() in one call, which is why it is useful to be able to pass
+around a single function pointer.
