Otherwise builtin_profiles contains dangling pointers the next time
_mesa_read_profile is called. I suspect this may fix bugzilla #29847,
but I was never able to reproduce it.
GL_EXT_texture_env_combine has slightly more restrictive limits on the
valid sources for some operands. This wasn't caught before because
almost every driver in Mesa that supports the EXT version also
supports the ARB version.
Inspired by a patch posted the the mesa-dev mailing list by Andrew
Randrianasulu.
Since we now actually destroy GLX drawables, we get into situations where
we get events for drawables that no longer exist. Just ignore the
event in that case.
Doesn't work for pixmaps, was looking up the GLX XID and was never thread
safe. Instead, just destroy the client side structures when the
drawable is no long current for a context.
libmesagallium.a that this state tracker will be linked to expects
OpenGL's _glapi_table. That is, it expects libGL.so instead of
libGLESv1_CM.so or libGLESv2.so. As there is no clean way to know the
shared library the app links to, use the api as a simple check. It
might be as well to simply remove this function call though.
Make st/dri screens capable of creating OpenGL ES and
OpenGL ES2 contexts.
TODO: Figure out the "get_current" problem with multiple
st_api's for real.

This allows them to be passed as out/inout parameters, but still
prevents them from being used as the target of an assignment. This is
per section 5.8 of the GLSL ES 1.00 specification.
This effectively reverts b6f15869b3.
In desktop GLSL, defining a function with the same name as a built-in
hides that built-in function completely, so there would never be
built-in and user function signatures in the same ir_function.
However, in GLSL ES, overloading built-ins is allowed, and does not
hide the built-in signatures - so we're back to needing this.
Fixes an assert (min_version >= 110) which was no longer correct, and
also prohibits linking ES2 shaders with non-ES2 shaders. I'm not
positive this is correct, but the specification doesn't seem to say.
This should make it easier to change the default version based on the
API (say, version 1.00 for OpenGL ES).
Also, synchronize the symbol table's version with the parse state's
version just before doing AST-to-HIR. This way, it will be set when
it matters, but the main initialization code doesn't have to care about
the symbol table.
This splits the r600 opcodes out of the sq file and adds a wrapper
so we can convert to evergreen opcodes later without touching these functions
too much.
DX9 constants were in the constant file, and evergreen no longer support
cfile. r600/700 can also use constants in memory buffers, so add the code
(disabled for now) to enable that as precursor for evergreen.
