* i965/gen6: Force WHILE exec size to 8.Eric Anholt2011-08-161-4/+2
| | | | | | | | | | 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.
* i965/vs: Remove remaining use of foreach_iter.Eric Anholt2011-08-162-9/+5
|
* i965/vs: Fix abs/negate handling on attributes.Eric Anholt2011-08-161-2/+9
| | | | Fixes glsl-vs-neg-attribute and glsl-vs-abs-attribute.
* i965/vs: Avoid generating a MOV for most ir_assignment handling.Eric Anholt2011-08-162-0/+73
| | | | | Removes an average of 11.5% of instructions in 54% of vertex shaders in shader-db.
* i965/vs: Run the shader backend at link time and return compile failures.Eric Anholt2011-08-166-20/+54
| | | | | | 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.
* i965: Fix assertion failure on a loop consisting of while (true) { break }.Eric Anholt2011-08-161-1/+1
| | | | | On enabling the precompile step in the VS, we tripped over this assertion failure in glsl-link-bug-30552.
* i965/vs: Fix the trivial register allocator's failure path.Eric Anholt2011-08-162-3/+5
|
* i965/vs: Add support for if(any(bvec)) on gen6.Eric Anholt2011-08-161-4/+8
|
* i965/vs: Add support for GL_FIXED attributes.Eric Anholt2011-08-161-0/+12
| | | | Fixes arb_es2_compatibility-fixed-type
* i965/vs: Clamp vertex color outputs when required by ARB_color_buffer_float.Eric Anholt2011-08-161-1/+10
| | | | Fixes glsl-vs-vertex-color.
* i965/vs: Fix access of attribute arrays.Eric Anholt2011-08-161-1/+2
| | | | | By leaving out the column index, we were reading an unallocated attribute on glsl-mat-attribute.
* i965/vs: Fix builtin uniform setup.Eric Anholt2011-08-161-3/+2
| | | | | 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.
* i965/vs: Add support for loops.Eric Anholt2011-08-161-32/+21
| | | | | 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.
* i965/vs: Add support for ir_binop_pow.Eric Anholt2011-08-163-7/+70
| | | | Fixes vs-pow-float-float.
* i965/vs: Respect the gen6 limitation that math opcodes can't be align16.Eric Anholt2011-08-162-2/+33
| | | | Fixes vs-acos-vec3 and friends.
* i965/vs: Fix implementation of ir_unop_any.Eric Anholt2011-08-161-1/+3
| | | | We were inheriting whatever previous predicate existed.
* i965/vs: Slightly improve the trivial reg allocator to skip unused regs.Eric Anholt2011-08-161-2/+24
| | | | | | | 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.
* i965: Add gen6 disassembly for DP render cache messages.Eric Anholt2011-08-161-3/+46
|
* i965/vs: Enable variable array indexing in the VS.Eric Anholt2011-08-161-5/+7
|
* i965/vs: Add support for scratch read/write codegen.Eric Anholt2011-08-162-2/+151
|
* i965: Make some EU emit code for DP read/write messages non-static.Eric Anholt2011-08-162-22/+49
| | | | | | | | 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.
* i965/vs: Move virtual GRFs with array accesses to them to scratch space.Eric Anholt2011-08-164-1/+186
|
* i965/vs: Reserve MRF 14/15 for array loads/register unspilling.Eric Anholt2011-08-161-6/+14
|
* i965/vs: Track the variable index of array accesses.Eric Anholt2011-08-162-4/+16
| | | | This isn't used currently, as we lower all array accesses.
* i965: Add remaining scratch space setup emit to unit states.Eric Anholt2011-08-164-3/+35
|
* i965: Set up allocation of a VS scratch space if required.Eric Anholt2011-08-165-22/+47
|
* i965: Remove dead brw->wm.max_threads field.Eric Anholt2011-08-161-1/+0
|
* i965/vs: Add support for VUEs larger than a single URB write.Eric Anholt2011-08-161-8/+34
| | | | Fixes glsl-max-varyings.
* i965/vs: Avoid generating extra moves when setting up large ir_constants.Eric Anholt2011-08-162-51/+28
| | | | | We were also screwing up the types in the process, and just not emitting moves was easier.
* i965/vs: Fix types of varying outputs.Eric Anholt2011-08-161-0/+1
| | | | | | | | | 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.
* i965/vs: Handle assignment of structures/arrays/matrices better.Eric Anholt2011-08-162-21/+51
| | | | | This gets the right types on the instructions, as well as emitting minimal swizzles/writemasks.
* i965/vs: Don't forget to set up assignment condition code for arrays/structs.Eric Anholt2011-08-161-0/+4
| | | | Fixes vs-uniform-array-mat2-index-col-rd.
* i965/vs: Apply the gen6 math workaround for math1 instructions.Eric Anholt2011-08-161-6/+4
| | | | Fixes glsl-vs-masked-cos.
* i965/vs: Add support for if(any_nequal()) and if(all_equal()) on gen6.Eric Anholt2011-08-162-4/+22
| | | | Fixes vs-temp-array-mat2-col-rd.shader_test.
* i965/vs: Add support for dot product opcodes.Eric Anholt2011-08-161-0/+12
| | | | Fixes glsl-vs-dot-vec2.
* i965/vs: Fix the types of array/struct dereferences.Eric Anholt2011-08-161-0/+2
| | | | Fixes glsl-vs-arrays-3.
* i965/vs: Drop the assertion about dst.reg_offset == 0.Eric Anholt2011-08-161-1/+0
| | | | | Adding the offset is the right thing to do here, and fixes glsl-vs-mat-add-1.
* i965/vs: Use an appropriate swizzle on src regs from variables.Eric Anholt2011-08-161-0/+4
| | | | Fixes glsl-vs-if-bool.
* i965/vs: Fix support for zero uniforms in use.Eric Anholt2011-08-161-1/+2
| | | | | We were looking for attributes in the wrong place, and pointlessly doing the work on gen6 at all.
* i965/vs: Fix support for "IF" instructions by copying brw_fs_visitor.cpp.Eric Anholt2011-08-161-4/+10
| | | | Fixes glsl-vs-if-greater.
* i965/vs: Disable loops for now until rendering is generally correct.Eric Anholt2011-08-161-0/+2
|
* i965/vs: Fix ir_swizzle handling.Eric Anholt2011-08-161-1/+1
| | | | | I decided to refactor it a bit in adapting ir_to_mesa.cpp code, and mangled it. Fixes glsl-vs-cross-2.
* i965/vs: Allocate storage for "auto" variables just like temps.Eric Anholt2011-08-161-0/+4
| | | | Fixes segfault in glsl-vs-cross-2.
* i965/vs: Allow scalar values in assignments, too.Eric Anholt2011-08-161-1/+2
| | | | Fixes glsl-vs-all-02 and many other tests.
* i965/vs: Don't emit an extra copy of the vertex position.Eric Anholt2011-08-161-6/+8
| | | | Fixes glsl-vs-abs-neg, glsl-vs-all-01, and probably many other tests.
* i965/vs: Port the fix for clip plane writemasks from brw_vs_emit.c.Eric Anholt2011-08-161-1/+1
|
* i965/vs: Fix constant vector construction.Eric Anholt2011-08-161-3/+3
| | | | Fixes some issues noticed in glsl-vs-all-01.
* i965/vs: Start adding support for uniformsEric Anholt2011-08-169-48/+256
| | | | There's no clever packing here, no pull constants, and no array support.
* i965: Start adding the VS visitor and codegen.Eric Anholt2011-08-1614-37/+2781
| | | | | | The low-level IR is a mashup of brw_fs.cpp and ir_to_mesa.cpp. It's currently controlled by the INTEL_NEW_VS=1 environment variable, and only tested for the trivial "gl_Position = gl_Vertex;" shader so far.
* i965: Rename math FS_OPCODE_* to SHADER_OPCODE_*.Eric Anholt2011-08-166-68/+68
| | | | I want to just use the same enums in the VS.
