i965/vs: Fix condition code for scalar expression all_equals.
...
Fixes vs-op-eq-bool-bool.

8a649277cb
i965/vs: Don't assertion fail on vertex texturing.
...
The linker will reject the program, but we need to survive until then.
Fixes abort in glsl1-2D Texture lookup with explicit lod (Vertex
shader)
2011-08-16 13:04:43 -07:00
d0c595ac80
i965/gen6: Force WHILE exec size to 8.
...
We can't just look at the instruction that happens to appear at the
start of the loop, because it might be some other exec size and cause
us to only loop on the first N channels. We always want 8 in our
current code (since 16 doesn't work so we don't do 16-wide fragment in
that case).
Fixes loop-03.vert, which was triggering the assertions.
2011-08-16 13:04:43 -07:00
905f3d0309
i965/vs: Remove remaining use of foreach_iter.
2011-08-16 13:04:43 -07:00
54e66a0a63
i965/vs: Fix abs/negate handling on attributes.

Fixes glsl-vs-neg-attribute and glsl-vs-abs-attribute.
2011-08-16 13:04:43 -07:00
7642c1de6b
i965/vs: Avoid generating a MOV for most ir_assignment handling.
...
Removes an average of 11.5% of instructions in 54% of vertex shaders
in shader-db.
2011-08-16 13:04:43 -07:00
7fbe7fe133
i965/vs: Run the shader backend at link time and return compile failures.
...
Link failure is something that shouldn't happen, but we sometimes want
it during development. The precompile also allows analysis of shader
codegen with shader-db.
2011-08-16 13:04:43 -07:00
d376fa8e84
i965: Fix assertion failure on a loop consisting of while (true) { break }.
...
On enabling the precompile step in the VS, we tripped over this
assertion failure in glsl-link-bug-30552.
2011-08-16 13:04:43 -07:00
e8980c61b2
i965/vs: Fix the trivial register allocator's failure path.

072d64121e
i965/vs: Add support for GL_FIXED attributes.

Fixes arb_es2_compatibility-fixed-type
2011-08-16 13:04:43 -07:00
aed5e353e9
i965/vs: Clamp vertex color outputs when required by ARB_color_buffer_float.
...
Fixes glsl-vs-vertex-color.
2011-08-16 13:04:43 -07:00
a55fbbc1a2
i965/vs: Fix access of attribute arrays.
...
By leaving out the column index, we were reading an unallocated
attribute on glsl-mat-attribute.
2011-08-16 13:04:43 -07:00
fea7d34b35
i965/vs: Fix builtin uniform setup.
...
I want to intelligently pack them at some point, but for now we have
the params set up in groups of 4. Fixes glsl-vs-normalscale.
2011-08-16 13:04:43 -07:00
0b359e3ea0
i965/vs: Add support for loops.
...
This is copied from brw_fs.cpp, instead of doing the temporary IR
generation that ir_to_mesa does. Fixes glsl-vs-loop and friends.
2011-08-16 13:04:43 -07:00
abf843a797
i965/vs: Add support for ir_binop_pow.

Fixes vs-pow-float-float.
2011-08-16 13:04:43 -07:00
250770b74d
i965/vs: Respect the gen6 limitation that math opcodes can't be align16.
...
Fixes vs-acos-vec3 and friends.
2011-08-16 13:04:43 -07:00
6408b0295f
i965/vs: Fix implementation of ir_unop_any.
...
We were inheriting whatever previous predicate existed.
2011-08-16 13:04:42 -07:00
7b91eefe7c
i965/vs: Slightly improve the trivial reg allocator to skip unused regs.
...
This fixes most of the regressions in the vs array test set from the
varying array indexing work, since the giant array that was originally
allocated in virtual GRF space never gets used and is only ever
read/stored from scratch space.
2011-08-16 13:04:42 -07:00
e94bdbe04a
i965: Add gen6 disassembly for DP render cache messages.

i965/vs: Enable variable array indexing in the VS.

i965/vs: Add support for scratch read/write codegen.
2011-08-16 13:04:42 -07:00
0f22f98ccd
i965: Make some EU emit code for DP read/write messages non-static.
...
We keep building these strange interfaces for DP read/write where
there's a helper function with some partially-specific,
partially-general controls, which is used in exactly one place in code
generation. Making these public will let us set up those instructions
in the one place they're to be generated.
2011-08-16 13:04:42 -07:00
d0e4d71070
i965/vs: Move virtual GRFs with array accesses to them to scratch space.
2011-08-16 13:04:42 -07:00
758c3c2b45
i965/vs: Reserve MRF 14/15 for array loads/register unspilling.
2011-08-16 13:04:42 -07:00
1ff4f11dd9
i965/vs: Track the variable index of array accesses.
...
This isn't used currently, as we lower all array accesses.
2011-08-16 13:04:42 -07:00
314c2574ff
i965: Add remaining scratch space setup emit to unit states.
2011-08-16 13:04:42 -07:00
2b224d66a0
i965: Set up allocation of a VS scratch space if required.

i965/vs: Add support for VUEs larger than a single URB write.
...
Fixes glsl-max-varyings.
2011-08-16 13:04:42 -07:00
31ef2e3ec2
i965/vs: Avoid generating extra moves when setting up large ir_constants.
...
We were also screwing up the types in the process, and just not
emitting moves was easier.
2011-08-16 13:04:42 -07:00
aba9801996
i965/vs: Fix types of varying outputs.
...
For structs/arrays/matrices, they were ending up as uint because we
forgot to set them. All varyings in GLSL 1.20 are of base type float,
so just force the matter here (which gets inherited at
emit_urb_writes() time).
Fixes vs-varying-array-mat2-col-rd.
2011-08-16 13:04:42 -07:00
9790726131
i965/vs: Handle assignment of structures/arrays/matrices better.
...
This gets the right types on the instructions, as well as emitting
minimal swizzles/writemasks.
2011-08-16 13:04:42 -07:00
930afd1774
i965/vs: Don't forget to set up assignment condition code for arrays/structs.

Fixes glsl-vs-masked-cos.
2011-08-16 13:04:42 -07:00
2b7632aeaa
i965/vs: Add support for if(any_nequal()) and if(all_equal()) on gen6.

Fixes vs-temp-array-mat2-col-rd.shader_test.
2011-08-16 13:04:42 -07:00
c3752b399a
i965/vs: Add support for dot product opcodes.

814a9bef30
i965/vs: Drop the assertion about dst.reg_offset == 0.

Adding the offset is the right thing to do here, and fixes
glsl-vs-mat-add-1.
2011-08-16 13:04:42 -07:00
e5363c7fd2
i965/vs: Use an appropriate swizzle on src regs from variables.

2011-08-16 13:04:42 -07:00
eca762d831
i965/vs: Fix support for zero uniforms in use.
...
We were looking for attributes in the wrong place, and pointlessly
doing the work on gen6 at all.
2011-08-16 13:04:42 -07:00
164ccd2778
i965/vs: Fix support for "IF" instructions by copying brw_fs_visitor.cpp.

bb468fc1ed
i965/vs: Fix ir_swizzle handling.
...
I decided to refactor it a bit in adapting ir_to_mesa.cpp code, and
mangled it. Fixes glsl-vs-cross-2.
2011-08-16 13:04:41 -07:00
78fac1892a
i965/vs: Allocate storage for "auto" variables just like temps.

a070d5f363
i965/vs: Start adding support for uniforms

There's no clever packing here, no pull constants, and no array support.
