System values are shader inputs which don't necessarily change from
vertex to vertex or fragment to fragment. gl_InstanceID and
gl_FrontFacing are examples.
Attribute 0 has no special meaning in GLES2. Add VertexAttrib4f_nopos
for that purpose and make _es_VertexAttrib* call the new function.
Rename _vbo_* to _es_* to avoid confusion. These functions are only
used by GLES, and now some of them (_es_VertexAttrib*) even behave
differently than vbo_VertexAttrib*.
CMP may now use two less temps, other non-native instructions may end up
using one less temp, except for SIN/COS/SCS, which I am leaving unchanged
for now.
This may reduce register pressure inside loops, because the register
allocator doesn't do a very good job there.
That's what I get for not running piglit before pushing.
Don't try to patch types of unsized arrays when linking fails.
Don't try to patch types of unsized arrays that are shared between
shader stages.
Fixes piglit test case glsl-vec-array (bugzilla #31908).
NOTE: This bug does not affect 7.9, but I think this patch is a
candiate for the 7.9 branch anyway.
Types of declared variables and their initializer must match excatly
except for unsized arrays. Previously the type inherritance for
unsized arrays happened implicitly in the emitted assignment.
However, this assignment is never emitted for uniforms. Now that type
is explicitly copied unconditionally.
Fixes piglit test array-compare-04.vert (bugzilla #32035) and
glsl-array-uniform-length (bugzilla #31985).
NOTE: This is a candidate for the 7.9 branch.
With the change of extended math from having the arguments moved into
mrfs and handed off through message passing to being directly hooked
up to the EU, it looks like the piece for doing source modifiers
(negate and abs) was left out.
Fixes:
fog-modes
glean/fp1-ARB_fog_exp test
glean/fp1-ARB_fog_exp2 test
glean/fp1-Computed fog exp test
glean/fp1-Computed fog exp2 test
ext_fog_coord-modes
Previously the code only handled scalars and vectors. This new code
is modeled somewhat after similar code in ir_to_mesa.

R6XX GPU doesn't like to have two partial flush writting
back to memory in row without a prior flush of the pipeline.
Add PS_PARTIAL_FLUSH to flush all work between the CP and
the ES, GS, VS, PS shaders.
Thanks a lot to Alban Browaeys (prahal on irc) for investigating
this issue.
