Without it gcc complains:
nv50_screen.c: In function ‘nv50_screen_is_format_supported’:
nv50_screen.c:48: warning: implicit declaration of function ‘util_format_is_supported’
and handles it wrongly - util_format_is_supported returns boolean, which is typedef'ed
to uchar, but function without prototype is assumed to return int.
For me nv50_screen_is_format_supported was returning true for float formats without
--enable-texture-float...
Sounds very unlikely, but I don't have a better explanation at the
moment.
The GPU throws page faults at the first page after the code buffer
quite frequently on startup, and traces don't show us overflowing.
This pass coverts CMP T0, T1 T2 T0 -> MOV T0, T2 when the CMP
instruction is the first instruction to write to register T0.
This pass is useful for hardware that requires a lot of lowering passes
that generate many CMP instructions.
So --enable-texture-float it is.
Hardware drivers (including the Gallium ones) should
use #ifdef TEXTURE_FLOAT_ENABLED to hide any code that may
expose floating-point renderbuffers via any interface,
public or private.
v2: Print a warning when using --enable-texture-float.

It's clear enough that the current segmentation fault isn't what we
want. And it's also very easy to know what we do want here, (just
check with any functional C preprocessor such as "gcc -E").
Add the desired output as an expected file so that the test suite
gives useful output, (showing the omitted output and the segfault),
rather than just reporting "No such file" for the expected file.
These were all written as generic list functions, (accepting and returning
a list to act upon). But they were only ever used with parser->active as
the list. By simply accepting the parser itself, these functions can update
parser->active and now return nothing at all. This makes the code a bit
more compact.
And hopefully the code is no less readable since the functions are also
now renamed to have "_parser_active" in the name for better correlation
with nearby tests of the parser->active field.
The common case for this test suite is to quickly test that everything
returns the correct results. In this case, the second run of the test
suite under valgrind was just annoying, (and the user would often
interrupt it).
Now, do what is wanted in the common case by default (just run the
test suite), and require a run with "glcpp-test --valgrind" in order
to test with valgrind.
The expected file here captures the current behavior of glcpp (which
is to generate an obscure "syntax error, unexpected $end" diagnostic
for this case).
It would certainly be better for glcpp to generate a nicer diagnostic,
(such as "missing closing parenthesis in function-like macro
definition" or so), but the current behavior is at least correct, and
expected. So we can make the test suite more useful by marking the
current behavior as expected.
The expected file here captures the current behavior of glcpp (which
is to generate a division-by-zero error) for this case.
It's easy to argue that it should be short-circuiting the evaluation
and not generating the diagnostic (which happens to be what gcc does).
But it doesn't seem like we should force this behavior on our
pre-processor, (and, as always, the GLSL specification of the
pre-processor is too vague on this point).
This test is behaving just fine already---it's generating an informative
diagnostic, ("error: division by 0 in preprocessor directive"), so adding
this in the expected file makes things pass.
We could actually try to do an early return both for gallium textures and
malloc memory textures, but I'm not sure exactly which situations
stImage->pt is NULL, and whether texImage->Data == NULL would be acceptible
or not.

This is the same as ARB_draw_buffers (which derived from it), except
for s/ARB/ATI/. The glapi bits were already in place, and what was
missing was just the ARB_fp part. The new Humble Bundle game "trine"
tries to use this extension without checking that it's exposed, which
this works around.

This is like what we do for add/mul, but we have to invert the
predicate to choose the other source instead.

By always using a boolean, we should generally avoid further
complaints. The failure case I see is logic_not, where the user might
understandably make the mistake of using `!' on a boolean vector (like
a piglit case did recently!), and then get a further complaint that
the new boolean type doesn't match the bvec it gets assigned to.
Fixes invalid-logic-not-06.vert (assertion failure when the bad type
ends up in an expression and ir_constant_expression gets angry).
