This can be used for two purposes: Using hand-coded shaders to determine
per-instruction timings, or figuring out which shader to optimize in a
whole application.
Note that this doesn't cover the instructions that set up the message to
the URB/FB write -- we'd need to convert the MRF usage in these
instructions to GRFs so that our offsets/times don't overwrite our
shader outputs.

v2: Check the timestamp reset flag in the VS, which is apparently
getting set fairly regularly in the range we watch, resulting in
negative numbers getting added to our 32-bit counter, and thus large
values added to our uint64_t.
v3: Rebase on reladdr changes, removing a new safety check that proved
impossible to satisfy. Add a comment to the AOP defs from Ken's
review, and put them in a slightly more sensible spot.
v4: Check timestamp reset in the FS as well.
Fixes flat shading for AA lines. demos/src/trivial/line-smooth is a
test case which hits this.

Serious Sam 3 had a shader hitting this path, but it's used rarely so it
didn't show a significant performance difference (n=7). It does reduce
compile time massively, though -- one shader goes from 14s compile time
and 11723 instructions generated to .44s and 499 instructions.
Note that some shaders lose 16-wide mode because we don't support
16-wide and pull constants at the moment (generally, things looping over
a few-element array where the loop isn't getting unrolled). Given that
those shaders are being generated with 15-20% fewer instructions, it
probably outweighs the loss of 16-wide.
The gen7 send-from-GRF path is sufficiently different from the perspective of
IR generation and optimization that I just made it a separate opcode.
v2: fix whitespace, rebase on Ken's recent refactor.
As of gen7, we can skip the header on some messages, and this can make
optimization on those messages much nicer when you've got GRFs instead of MRFs
as the source.
This is a temporary hack. I believe the only way of properly fixing this
is to check buffer overflow just before fetching based on addresses,
instead of number of vertices/instances. This change simply allows tests
that stress buffer overflows to complete without asserting, and should
not affect valid rendering.

We need to clamp vertex buffer fetch based on its size, not based on the
user specified max index hint.

A single vertex size is chosen for the whole pipeline. So the number of

This fixes fdo bug 57755 and most of the failures of piglit fbo-blending-formats
GL_EXT_texture_snorm.
GL_INTENSITY_SNORM is still failing, but problem is probably elsewhere,
as GL_R8_SNORM works fine.
Now that _mesa_BindFramebuffer does the right thing in ES contexts when the
gl_extensions::ARB_framebuffer_object bit is set, the Intel driver doesn't
need this hack.
No piglit or GLES2 conformance regressions observed on IVB, and this
patch (and the previous) fix es3conform's framebuffer_srgb_draw and

Desktop OpenGL implementations that support either
GL_ARB_framebuffer_object or OpenGL 3.0 must require names from
glGenFramebuffers for glBindFramebuffer. We have enforced this rule for
quite some time. However, OpenGL ES 1.0, 2.0, and 3.0 implementations
are required to allow user-defined names (e.g., not from
glGenFramebuffers{OES,}).
The Intel drivers have hacked around this by not enabling
GL_ARB_framebuffer_object in an ES context. Instead, just pick the
correct behavior in _mesa_BindFramebuffer based on the context API.
Chad pointed out in a review e-mail:
"I'd like to point out, though, that glBindFramebufferEXT and
glBindRenderbufferEXT are still broken on desktop GL because they
don't accept user-genned names. But that fix belongs to a different
series."
Currently glBindFramebufferEXT is an alias for glBindFramebuffer.
Unalising two functions presents some difficulty, so we'll have to
revisit this eventually.
v2: Perform same check in _mesa_BindRenderbuffer too.

The NV formulation of primitive restart is turned on/off with
glEnableClientState/glDisableClientState. These two functions don't
exist in core contexts, which mean that GL_NV_primitive_restart is
essentially useless...even broken.
However, leaving it on causes oglconform's primitive-restart-nv tests to
run in OpenGL 3.1 contexts, which results in them all failing. This
patch causes 29 subtests to go from "fail" to "not run".
