12 years agoglsl: validate IR after linking (debug builds only)
Paul Berry [Wed, 3 Aug 2011 22:37:01 +0000 (15:37 -0700)]
glsl: validate IR after linking (debug builds only)

At least one of the invariants verified by IR validation concerns the
relative ordering of toplevel constructs in the IR: references to
global variables must come after the declarations of those global
variables.

Since linking affects the ordering of toplevel constructs in the IR,
it's possible that a bug in the linker will cause invalid IR to be
generated, even if all the pre-linked shaders are valid.  (In fact,
such a bug was fixed by the previous commit.)

Bugs like this are easily masked by further optimization passes,
particularly inlining.  So to make them easier to track down, this
patch addes an IR validation step right after linking, and before
final optimization occurs.  The validation only occurs on debug
builds.

glsl: When linking, emit functions at the tail of the final linked program.

When link_functions.cpp adds a new function to the final linked

that the function refers to, otherwise the IR will be invalid (because
variable declarations must occur before variable accesses).  The
easiest way to do that is to have the linker emit functions to the
tail of the final linked program.

The linker used to emit functions to the head of the final linked
program, in an effort to keep callees sorted before their callers.
However, this was not reliable: it didn't work for functions declared

12 years agoglsl: Emit function signatures at toplevel, even for built-ins.
Paul Berry [Fri, 29 Jul 2011 22:28:52 +0000 (15:28 -0700)]
glsl: Emit function signatures at toplevel, even for built-ins.

The ast-to-hir conversion needs to emit function signatures in two
circumstances: when a function declaration (or definition) is
encountered, and when a built-in function is encountered.

To avoid emitting a function signature in an illegal place (such as
inside a function), emit_function() checked whether we were inside a
function definition, and if so, emitted the signature before the
function definition.

However, this didn't cover the case of emitting function signatures
for built-in functions when those built-in functions are called from
inside the constant integer expression that specifies the length of a
global array.  This failed because when processing an array length, we
are emitting IR into a dummy exec_list (see process_array_type() in
ast_to_hir.cpp).  process_array_type() later checks (via an assertion)
that no instructions were emitted to the dummy exec_list, based on the
reasonable assumption that we shouldn't need to emit instructions to
calculate the value of a constant.

This patch changes emit_function() so that it emits function
signatures at toplevel in all cases.

This partially fixes bug 38625
(https://bugs.freedesktop.org/show_bug.cgi?id=38625).  The remainder
of the fix is in the patch that follows.

12 years agoRevert "glsl: Skip processing the first function's body in do_dead_functions()."
Paul Berry [Mon, 1 Aug 2011 20:06:06 +0000 (13:06 -0700)]
Revert "glsl: Skip processing the first function's body in do_dead_functions()."

opt_dead_functions contained a shortcut to skip processing the first
function's body, based on the assumption that IR functions are
topologically sorted, with callees always coming before their callers
(therefore the first function cannot contain any calls).

This assumption turns out not to be true in general.  For example, the
following code snippet gets translated to IR that violates this
assumption:

    void f();
    void g();
    void f() { g(); }
    void g() { ... }

In practice, the shortcut didn't cause bugs because of a coincidence
of the circumstances in which opt_dead_functions is called:

(a) we do inlining right before dead function elimination, and
    inlining (when successful) eliminates all calls.

(b) for user-defined functions, inlining is always successful, because
    previous optimization passes (during compilation) have reduced
    them to a form that is eligible for inlining.

(c) the function that appears first in the IR can't possibly call a
    built-in function, because built-in functions are always emitted
    before the function that calls them.

It seems unnecessarily fragile to have opt_dead_functions depend on
these coincidences.  And the next patch in this series will break (c).
So I'm reverting the shortcut.  The consequence will be a slight
increase in link time for complex shaders.

Rely on the driver to do the right thing.  This probably means falling
back to software.  Page 88 of the OpenGL 2.1 spec specifically says:

    "A shader should not fail to compile, and a program object should
    not fail to link due to lack of instruction space or lack of
    temporary variables. Implementations should ensure that all valid
    shaders and program objects may be successfully compiled, linked
    and executed."

There is no provision for saying "No" to a valid shader that is
difficult for the hardware to handle, so stop doing that.

On i915 this causes a large number of piglit tests to change from FAIL
to WARN.  The warning is because the driver still emits messages to
stderr like "i915_program_error: Unsupported opcode: BGNLOOP".

It also fixes ES2 conformance CorrectFull_frag and CorrectParse1_frag
on i915 (and probably other hardware that can't handle loops).
