This code should never have been triggered, but I often did anyway
when I disabled optimization passes during debugging, then spent my
time debugging that this code doesn't work.
|
|
No effect, since it was called before live intervals were calculated.
|
|
The comment of "this is just like teximages except for..." is a pretty
good clue that we're handling this wrong. By just using the teximage
code, we catch a bunch of cases we'd missed, like GL_RED and GL_RG.
|
|
This catches more opportunities than the prog_optimize.c code on
openarena's fixed function shaders turned to GLSL, mostly due to
looking at multiple source instructions for copy propagation
opportunities. It should also be much more CPU efficient than
prog_optimize.c's code.

The usage of macro V_SQ_ALU_WORD1_OP2_SQ_OP2_INST_FLT_TO_INT_FLOOR was
introduced by commit 323ef3a1f07ba4333dadebab571ddcd49d95f45c but the
macro is undefined. Disable this case to fix the build for now.

Fix a copy-and-paste error in a4a38dcf61f141297a083ccac217200947d57b0d.

dpy->ClientAPIs was renamed in a4a38dcf61f141297a083ccac217200947d57b0d.

Until we get the EXT_framebuffer_sRGB extension we should bind the sRGB
formats for FBO as linear.

OES_standard_derivatives must be manually disabled for i915 because Mesa
enables it by default.
|
|
Add a bit in struct gl_extensions for OES_standard_derivatives, and enable
the bit by default. Advertise the extension only if the bit is enabled.
Previously, OES_standard_derivatives was advertised in GLES2 contexts
if ARB_framebuffer_object was enabled.

Fixes SCons build.

'varying'
The specs that add 'layout' require the use of 'in' or 'out'.
However, a number of implementations, including Mesa, shipped several
of these extensions allowing the use of 'varying' and 'attribute'.
For these extensions only a warning is emitted.
This differs from the behavior of Mesa 7.10. Mesa 7.10 would only
accept 'attribute' with 'layout(location)'. This behavior was clearly
wrong. Rather than carrying the broken behavior forward, we're just
doing the correct thing.
This is related to (piglit) bugzilla #31804.
NOTE: This is a candidate for the 7.9 and 7.10 branches.

All of the extensions that add the 'layout' keyword also enable (and
required) the use of 'in' and 'out' with shader globals.
This is related to (piglit) bugzilla #31804.

Hairy stuff. Don't know how to do it better though.

Point smoothing requires rasterization rules to be set to OGL.
Sorry for the extra noise caused by the header update.

When use_spoken is true, istart (the first vertex of this segment) is
replaced by i0 (the spoken vertex of the fan). There are still icount
vertices.
Thanks to Brian Paul for spotting this.

Without this, X doesn't start with UMS on r300g.

But without creating liblibOpenVG or liblibEGL elsewhere.
Thanks Chia-I Wu for pointing this out.

The idea is to be able to match a driver using the following order
try egl_gallium with hw renderer
try egl_dri2
try egl_gallium with sw renderer
try egl_glx
given the module list
egl_gallium
egl_dri2
egl_glx
For that, UseFallback initialization option is added. The module list
is matched twice: with the option unset and with the option set. In the
first pass, egl_gallium skips its sw renderer and egl_glx rejects to
initialize since UseFallback is not set. In the second pass,
egl_gallium skips its hw renderer and egl_dri2 rejects to initialize
since UseFallback is set. The process stops at the first driver that
initializes the display.
|
|
Add initialization options that drv->API.Initialize should support.
Replace drv->Probe by TestOnly initialization option and simplify
_eglMatchDriver.
|
|
Reorder/rename and document the fields that should be set by the driver during
initialization. Drop the major/minor arguments from drv->API.Initialize.

This isn't strictly necessary, but is definitely nicer.
|
|
You can now simply write (assign (xy) <lhs> <rhs>) instead of the
verbose (assign (constant bool (1)) (xy) <lhs> <rhs>).
|
|
This makes it unnecessary to pass _mesa_glsl_parse_state around
everywhere, making at least the prototypes a lot easier to read.
It's also more C++-ish than a pile of static C functions.
|
|
These used to be more complicated, but now are so simple there's no real
point in keeping them separate.
|
|
All of these functions used to take s_list pointers so they wouldn't all
need SX_AS_LIST conversions and error checking. However, the new
pattern matcher conveniently does this for us in one centralized place.
So there's no need to insist on s_list. Switching to s_expression saves
a bit of code and is somewhat cleaner.
|
|
Most code now relies on the pattern matcher rather than this function,
and for the only remaining case, not using this saves an iteration.
|
|
Previously, the IR reader was riddled with code that:
1. Checked for the right number of list elements (via a linked list walk)
2. Retrieved references to each component (via ->next->next pointers)
3. Downcasted as necessary to make sure that each sub-component was the
right type (i.e. symbol, int, list).
4. Checking that the tag (i.e. "declare") was correct.
This was all very ad-hoc and a bit ugly. Error checking had to be done
at both steps 1, 3, and 4. Most code didn't even check the tag, relying
on the caller to do so. Not all callers did.
The new pattern matching module performs the whole process in a single
straightforward function call, resulting in shorter, more readable code.
Unfortunately, MSVC does not support C99-style anonymous arrays, so the
pattern must be declared outside of the match call.
