We'll need to use the HALT instruction to do this right, like returns
from other functions.
|
| |
|
|

This still needs work, passes tex3d, fbo-scissor-bitmap, scissor-bitmap

We were putting the source pointer in a register used as a temporary,
breaking all paths that don't read the data in a single instruction.

h needs to be rounded up, this probably needs revisiting when we get
to tiling etc.

8 more piglit tests pass,
fbo-clearmipmap, fbo-copyteximage, fbo-generatemipmap,
fbo-generatemipmap-nonsquare, fbo-generatemipmap-scissor,
fbo-generatemipmap-viewport, gen-teximage, gen-texsubimage

These binops are the vector-to-bool comparisons, not vec-to-bvec. We
likely want both operations avilable as expression, since 915 and 965
FS naturally does the vector version, while 965 VS can also naturally
do the scalar version. However, we can save that until later.
Fixes:
glsl-fs-vec4-operator-equal.shader_test
glsl-fs-vec4-operator-notequal.shader_test
glsl-vs-vec4-operator-equal.shader_test
glsl-vs-vec4-operator-notequal.shader_test

Fixes glsl-fs-sign and many of the tests of trig builtins.
|
| |
|

Fixes glsl-unused-varying and many others, since we produce an output
reg read any time gl_FragColor is written inside an if statement.

Now that we have glsl2 with if flattening in place, most shaders will
just work. Remaining failing shaders will mostly be due to loop
unrolling (in progress), some possible if flattening failures in
inlining functions (planning on fixing), and the register/instruction
count limits.
While the GLSL and GLSL-ES specs say that shaders shouldn't fail to
compile/link due to register/instruction limits, in practice we're not
the first vendor to expose GLSL on hardware with these limitations.
The benefit to application developers of providing a better language
for GPU programming is greater than the pain of having to handle
instruction limits (which they had to for ARB_fp on this hardware
anyway)

This error led to an assertion failure for some constructors of
non-square matrices. It only occured in matrices where the number of
columns was greater than the number of rows. It didn't even always
occur on those.
Fixes piglit glslparsertest case constructor-16.vert.

with glsl2, reads from outputs are legal

Fixes piglit test case glsl-vs-ff-frag and bugzilla #29623.

In one optimization pass, register files may have been messed therefore
merging instructions which use the same index in two different register
files.

When simplifying (vec4(1.0) / (float(x))) to rcp(float(x)), we forgot
to produce a vec4, angering ir_validate when starting alien-arena.
Fixes:
glsl-algebraic-add-zero-2
glsl-algebraic-div-one-2
glsl-algebraic-mul-one-2
glsl-algebraic-sub-zero-3
glsl-algebraic-rcp-sqrt-2

This could reduce the amount of memory used by a shader tree after
optimization, and increases consistency with other passes.

Several optimization paths, including constant folding, can lead to
accessing an ir_constant array with an out of bounds index. The GLSL
spec lets us produce "undefined" results, but it does not let us
crash.
Fixes piglit test case glsl-array-bounds-01 and glsl-array-bounds-03.

This will make extracting source to produce minimal testcases for
shader compile issues easier.

Use DRI_LIB_DEPS when linking GL/GLES state trackers. This fixes
missing talloc symbol errors, and is hopefully more future proof.

Apart from the fact that the radeon.h/r600_states.h editing is a nightmare, this
wasn't so bad.
passes piglit user-clip test now also trivial tests.

This saves an extra message reg move in the program, though I'm not
clear on whether it will have any performance impact other than cache
footprint. It will also fix those math calls on Sandybridge, where
the brw_eu_emit.c brw_math() support relies on the implied move being
used.

Many functions are currently wrapped with #if 0 since we haven't

This was causing line numbering to be off by one. The newline comes
from the NEWLINE token at the end of the line; there's no need to
insert one.
