This patch makes changes to the behavior of glGetAttribLocation(),
glGetFragDataLocation() and glGetFragDataIndex() functions.
Code changes handle a case described in following example:
shader program:
layout(location = 1)in vec4[4] a;
void main()
{
}
Currently, glGetAttribLocation("a") returns 1.
glGetAttribLocation("a[i]"), where i = {0, 1, 2, 3}, returns -1.
But the expected locations for array elements are: 1, 2, 3 and 4
respectively.
This clarification came up with the addition of
ARB_program_interface_query to OpenGL 4.3.
From Page 326 (page 347 of the PDF) of OpenGL 4.3 spec:
"Otherwise, the command is equivalent to
GetProgramResourceLocation(program, PROGRAM_INPUT, name);"
And, From Page 101 (page 122 of the PDF) of OpenGL 4.3 spec:
"A string provided to GetProgramResourceLocation or
GetProgramResourceLocationIndex is considered to match an active
variable if
• the string exactly matches the name of the active variable;
• if the string identifies the base name of an active array, where
the string would exactly match the name of the variable if the
suffix "[0]" were appended to the string; or
• if the string identifies an active element of the array, where
the string ends with the concatenation of the "[" character, an
integer (with no "+" sign, extra leading zeroes, or whitespace)
identifying an array element, and the "]" character, the integer
is less than the number of active elements of the array variable,
and where the string would exactly match the enumerated name of
the array if the decimal integer were replaced with zero."
V2: Simplify get_matching_index() function.

Currently overlapping locations of input variables are not allowed for all

From OpenGL ES 3.0 spec, page 56:
"Binding more than one attribute name to the same location is referred
to as aliasing, and is not permitted in OpenGL ES Shading Language
3.00 vertex shaders. LinkProgram will fail when this condition exists.
However, aliasing is possible in OpenGL ES Shading Language 1.00 vertex
shaders."
Taking in to account what different versions of OpenGL and OpenGL ES specs
say about aliasing:
- It is allowed only on vertex shader input attributes in OpenGL (2.0 and
above) and OpenGL ES 2.0.
- It is explictly disallowed in OpenGL ES 3.0.

For platforms using hardware contexts (currently Gen6+), we failed to
emit PIPELINE_SELECT and 3DSTATE_VF_STATISTICS, instead emitting MI_NOOP
for both.
During one of the context initialization reordering patches, we
accidentally moved brw_init_state before we set brw->CMD_PIPELINE_SELECT
and brw->CMD_VF_STATISTICS. So, when brw_init_state uploaded initial
GPU state (brw_init_state -> brw_upload_initial_gpu_state ->
brw_upload_invariant_state), these would be 0 (MI_NOOP).
Storing the commands in the context is not worthwhile. We have many
generation checks in our state upload code, and for platforms with
hardware contexts, this only gets called once per GL context anyway.
The cost is negligable, and it's easy to botch context creation
ordering.
This may fix hangs on Gen6+ when using the media pipeline.

(cherry picked from commit 0380ec467d)
We've had several problems now with FinishRenderTexture not getting called
enough, and we're ready to just give up on it ever doing what we need. In
particular, an upcoming Steam title had rendering bugs that could be fixed
by always_flush_cache=true.
Instead of hoping Mesa core can figure out when we need to flush our
caches, just track what BOs we've rendered to in a set, and when we render
from a BO in that set, emit a flush and clear the set.
There's some overhead to keeping this set, but most of that is just
hashing the pointer -- it turns out our set never even gets very large,
because cache flushes are so common (even on cairo-gl).
No statistically significant performance difference in cairo-gl (n=100),
despite spending ~.5% CPU in these set operations.
v1: (Original patch by Eric Anholt.)
v2: (Changes by Ken Graunke.)
- Rebase forward from May 7th 2013 -> March 4th 2014.
- Drop the FinishRenderTexture hook entirely; after rebasing the
patch, the hook was just an empty function.
- Move the brw_render_cache_set_clear() call from
intel_batchbuffer_emit_flush() to brw_emit_pipe_control_flush().
In theory, this could catch more cases where we've flushed.
- Consider stencil as a possible texturing source.
v3: (changes by anholt):
- Move set_clear() back to emit_mi_flush() -- it means we can drop
more forced flushes from the code. In the previous location, it
wouldn't have been called when we wanted pre-gen6.
- Move the set clear from batch init to reset -- it should be empty at
the start of every batch, since the kernel handled any inter-batch
flush for us.
v4: Drop the debug code in set.c that I accidentally committed.
v5: Back port to 10.1 stable branch (remove reference to stencil texture.)
