The string is only applied when the context is API_OPENGLES2.
The bulk of the change is to prevent overriding the context to
API_OPENGL_CORE based on the requested version. If the context is
API_OPENGL_ES2, don't change it.

This is a bit of a hack for now. Several of the extensions required for
OpenGL ES 3.1 have no support, at all, in Mesa. However, with this
patch and a patch to allow MESA_GL_VERSION_OVERRIDE to work with ES
contexts, people can begin testing the ES "version" of the functionality
that is supported.

If the multiplication's result is unused, except by a conditional_mod,
the destination will be null. Since the final instruction in the lowered
sequence is a partial-write, we can't put the conditional mod on it and
we have to store the full result to a register and do a MOV with a
conditional mod.

When we compute the output swizzle we want to consider the number of

Trivial.
The idea I had when I wrote the original shadow code was that you'd see a
set_index_buffer to the IB, then a bunch of draws out of it. What's
actually happening in openarena is that set_index_buffer occurs at every
draw, so we end up making a new shadow BO every time, and converting more
of the BO than is actually used in the draw.
While I could maybe come up with a better caching scheme, for now just
do the simple thing that doesn't result in a new shadow IB allocation
per draw.
Improves performance of isosurf in drawelements mode by 58.7967% +/-
3.86152% (n=8).
We'd sometimes try to reallocate something that X was using as a new
pipe_resource, and potentially conflict in our rendering. But even
worse, if we reallocated the BO as a shader, the kernel would reject
rendering using the shader.
Not sure what happened in my testing that made the previous shadow
code fix glxgears swapbuffering, but this also fixes lots of CopyArea
in X (like dragging xlogo around in metacity).
I forgot to make the change in 96f164f6f0.
This fixes a warning with GCC and probably an error with Clang.

Starting with GEN8, there is documentation that the multisample state command
must be emitted before the 3DSTATE_WM_HZ_OP command any time the multisample
count changes. The 3DSTATE_WM_HZ_OP packet gets emitted as a result of a
intel_hix_exec(), which is called upon a fast clear and/or a resolve. This can
happen before the state atoms are checked, and so the multisample state must be
put directly in the function.
v1:
- In v0, I was always emitting the command, but Ken came up with the condition to
determine whether or not the sample count actually changed.
- Ken's recommendation was to set brw->num_multisamples after emitting
3DSTATE_MULTISAMPLE. This doesn't work. I put my best guess as to why in the XXX
(it was causing 7 regressions on BDW).
v2:
Flag NEW_MULTISAMPLE state. As Ken found, in state upload we check for the
multisample change to determine whether or not to emit certain packets. Since
the hiz code doesn't actually care about the number of multisamples, set the
flag and let the later code take care of it.

Fixes around 200 piglit tests on SKL. I'm somewhat surprised that it seems to
have no impact on BDW as the restriction is needed there as well.

Commit 4bdbb588a9 introduced new _glapi_new_nop_table() and
_glapi_set_nop_handler() functions in the glapi dispatcher (which
live in libGL.so). The calls to those functions from context.c
would be undefined (i.e. an ABI break) if the libGL used at runtime
was older.
For the time being, use the old single generic_nop() function for
non-Windows builds to avoid this problem. At some point in the future
it should be safe to remove this work-around. See comments for more
details.

argparse type is a nice type saver for simple data types, but it doesn't
look a good fit for the input XML file:
- Certain implementations of argparse (particularly python 2.7.3's)
invoke the type constructor for the default argument even when an
option is passed in the command line. Causing `No such file or
directory: 'gl_API.xml'` when the current dir is not
src/mapi/glapi/gen.
- The parser takes multiple arguments. This is currently worked around
using lambdas, but that unnecessarily complex and hard to read.
Furthermore it's odd to have a side-effect as heavy as parsing XML
happening deep inside the argument parsing.

Without it, texcoords are mapped to GENERIC[0..7], PointCoord is mapped to
GENERIC[8], and user-defined varyings start from GENERIC[9]. Since texcoords
can only be used between VS and PS, and PointCoord is PS-only, it's silly to
always start from GENERIC[9] in all other shaders (such as LS, HS, ES, GS).
This adds support for TEXCOORD and PCOORD semantics. As a result, st/mesa
will use GENERIC[0] as a base for user-defined varyings, which should make
linking ES and GS as well as tessellation shaders at runtime easier.
