glsl/glcpp: Add test script for testing various line-termination characters

The GLSL specification has a very broad definition of what is a
newline. Namely, it can be the carriage-return character, '\r', the newline
character, '\n', or any combination of the two, (though in combination, the
two are treated as a single newline).

Here, we add a new test-runner, glcpp-test-cr-lf, that, for each possible
line-termination combination, runs through the existing test suite with all
source files modified to use those line-termination characters. Instead of
using the .expected files for this, this script assumes that the regular test
suite has been run already and expects the output to match the .out
files. This avoids getting 4 test failures for any one bug, and instead will
hopefully only report bugs actually related to the line-termination
characters.

The new testing is not yet integrated into "make check". For that, some
munging of the testdir option will be necessary, (to support "make check" with
out-of-tree builds). For now, the scripts can just be run directly by hand.

glsl/glcpp: Fix for macros that expand to include "defined" operators

Prior to this commit, the following snippet would trigger an error in glcpp:

#define FOO defined BAR
#if FOO
        #endif

The problem was that support for the "defined" operator was implemented within
the grammar, (where the parser was parsing the tokens of the condition
itself). But what is required is to interpret the "defined" operator that
results after macro expansion is performed.

I could not find any fix for this case by modifying the grammar alone. The
difficulty is that outside of the grammar we already have a recursive function
that performs macro expansion (_glcpp_parser_expand_token_list) and that
function itself must be augmented to be made aware of the semantics of the
"defined" operator.

The reason we can't simply handle "defined" outside of the recursive expansion
function is that not only must we scan for any "defined" operators in the
original condition (before any macro expansion occurs); but at each level of
the recursive expansion, we must again scan the list of tokens resulting from
expansion and handle "defined" before entering the next level of recursion to
further expand macros.

And of course, all of this is context dependent. The evaluation of "defined"
operators must only happen when we are handling preprocessor conditionals,
(#if and #elif) and not when performing any other expansion, (such as in the
main body).

To implement this, we add a new "mode" parameter to all of the expansion
functions to specify whether resulting DEFINED tokens should be evaluated or
ignored.

One side benefit of this change is that an ugly wart in the grammar is
removed. We previously had "conditional_token" and "conditional_tokens"
productions that were basically copies of "pp_token" and "pp_tokens" but with
added productions for the various forms of DEFINED operators. With the new
code here, those ugly copy-and-paste productions are eliminated from the
grammar.

A new "make check" test is added to stress-test the code here.

glsl/glcpp: Add explicit error for "#define without macro name"

Previously, glcpp would emit an error like this if <EOF> happened to occur
immediately after the "#define", but in general would just get confused,
(leading to un-helpful error messages).

To fix things to generate a clean error message, we do a few things:

1. Don't require horizontal whitespace immediately after #define

2. Add a production for the error case, (DEFINE_TOKEN followed
   immediately by a NEWLINE token).

3. Make the lexer reset to the <INITIAL> state after every NEWLINE.

This 3rd point prevents the lexer from getting so confused and generating
further spurious errors in the file because it was stuck in the <DEFINE> start
condition.

We also drop the similar error message from the <EOF> rule since the
newly-added rule will have already printed the error message.

draw: fix clipvertex trouble if position comes from gs

If the vertex shader has no position but the gs has, the clipvertex output
was -1 (because it's the same as vs position in this case if there's no

Rather than just test for -1 cv value in clipping, make it explicitly return
the position output of the gs instead which seems cleaner (since we really
don't want to use the clipvertex value from the vs (it could be a valid value

glsl: Rebuild the symbol table without unreachable symbols

Previously we had to keep unreachable global symbols in the symbol table
because the symbol table is used during linking.  Having the symbol
table retain pointers to freed memory... what could possibly go wrong?
At the same time, this meant that we kept live references to tons of
memory that was no longer needed.

New strategy:  destroy the old symbol table, and make a new one from the
reachable symbols.

v2: (by Kenneth Graunke) Just add the ir_function from the IR stream,

glsl: Only create one ir_function for a given name.

Piglit's spec/glsl-1.10/linker/override-builtin-{const,uniform}-05 tests
do the following:

1. Call abs(float) - a built-in function.
2. Create a user-defined replacement for abs(float).
3. Call abs(float) again - now the user function.

At step 1, we created an ir_function which included the built-in
signature, added it to the symbol table, and emitted it into the IR
stream.

Then, when processing the function definition at step 2, we'd see that
there was already an ir_function.  But, since there were no user-defined
functions, we skipped over a bunch of code, and ended up creating a
second one.  This new ir_function shadowed the original in the symbol
table, but both ended up in the IR stream.

This results in an awkward situation where searching for an ir_function
via the symbol table, a forward linked list walk, and a reverse linked
list walk may return different ir_functions.  This seems undesirable.

This patch instead re-uses the existing ir_function, putting both
built-in and user-defined signatures in the same one.  The previous
patch's additional filtering ensures everything continues working.

glsl: Make it possible to ignore built-ins when matching signatures.

Historically, we've implemented the rules for overriding built-in
functions by creating multiple ir_functions and relying on the symbol
table to hide the one containing built-in functions.  That works, but
has a few drawbacks, so the next patch will change it.

Instead, we'll have a single ir_function for a particular name, which
will contain both built-in and user-defined signatures.  Passing an
extra parameter to matching_signature makes it easy to ignore built-ins
when they're supposed to be hidden.

I didn't add the parameter to exact_matching_signature since it wasn't
necessary.

glsl: Do not eliminate 'shared' or 'std140' blocks or block members

Commit 32f32292 (glsl: Allow elimination of uniform block members)
enabled elimination of unused uniform block members to fix a gles3
conformance test failure.  This went too far the other way.

Section 2.11.6 (Uniform Variables) of the OpenGL ES 3.0.3 spec says:

    "All members of a named uniform block declared with a shared or
    std140 layout qualifier are considered active, even if they are not
    referenced in any shader in the program. The uniform block itself is
    also considered active, even if no member of the block is
    referenced."
