* i965: Fix stride field for the result of emit_uniformize().Francisco Jerez2015-07-214-19/+26
| | | | | | | | | | | | | | | | | | | This is essentially the same problem fixed in an earlier patch for immediates. Setting the stride to zero will be particularly useful for my future SIMD lowering pass, because we will be able to just check whether the stride of a source register is zero and skip emitting the copies required to unzip it in that case. Instead of setting stride to zero in every caller of emit_uniformize() I've changed the function to return the result as its return value (previously it was being written into a caller-provided destination register), because this way we can enforce that the result is used with the correct regioning from the function itself. The changes to the prototype of its VEC4 counterpart are mainly for the sake of symmetry, VEC4 registers don't have stride. Reviewed-by: Samuel Iglesias Gonsálvez <[email protected]>
* i965/fs: Fix stride field for uniforms.Francisco Jerez2015-07-211-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes essentially the same problem as for immediates. Registers of the UNIFORM file are typically accessed according to the formula: read_uniform(r, channel_index, array_index) = read_element(r, channel_index * 0 + array_index * 1) Which matches the general direct addressing formula for stride=0: read_direct(r, channel_index, array_index) = read_element(r, channel_index * stride + array_index * max{1, stride * width}) In either case if reladdr is present the access will be according to the composition of two register regions, the first one determining the per-channel array_index used for the second, like: read_indirect(r, channel_index, array_index) = read_direct(r, channel_index, read(r.reladdr, channel_index, array_index)) where: read(r, channel_index, array_index) = if r.reladdr == NULL then read_direct(r, channel_index, array_index) else read_indirect(r, channel_index, array_index) In conclusion we can handle uniforms consistently with the other register files if we set stride to zero. After lowering to a GRF using VARYING_PULL_CONSTANT_LOAD in demote_pull_constant_loads() the stride of the source is set to one again because the result of VARYING_PULL_CONSTANT_LOAD is generally non-uniform.

* i965/fs: Fix stride for immediate registers.Francisco Jerez2015-07-212-0/+7
| | | | | | | | | | | | | | | | | | | When the width field was removed from fs_reg the BROADCAST handling code in opt_algebraic() started to miss a number of trivial optimization cases resulting in the ugly indirect-addressing sequence to be emitted unnecessarily for some variable-indexed texturing and UBO loads regardless of one of the sources of BROADCAST being immediate. Apparently the reason was that we were setting the stride field to one for immediates even though they are typically uniform. Width used to be set to one too which is why this optimization used to work previously until the "reg.width == 1" check was removed. The stride field of vector immediates is intentionally left equal to one, because they are strictly speaking not uniform. The assertion in fs_generator makes sure that immediates have the expected stride as consistency check. Reviewed-by: Samuel Iglesias Gonsálvez <[email protected]>
* i965/vec4: Fix liveness analysis with BRW_OPCODE_SELIago Toral Quiroga2015-07-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | We only consider a vgrf defined by a given block if the block writes to it unconditionally. So far we have been checking this by testing that the instruction is not predicated, however, in the case of BRW_OPCODE_SEL, the predication is used to select the value to write, not to decide if the write is actually done. The consequence of this was increased life spans for affected vgrfs, which could lead to additional register pressure. Since NIR generates selects for conditional writes this was causing massive register pressure in a handful of piglit and dEQP tests that had a large number of select operations with the NIR-vec4 backend. Fixes the following piglit tests with the NIR-vec4 backend: spec/glsl-1.50/execution/variable-indexing/vs-output-array-vec4-index-wr-before-gs spec/glsl-1.50/execution/variable-indexing/gs-input-array-vec4-index-rd spec/glsl-1.50/execution/variable-indexing/vs-output-array-vec2-index-wr-before-gs spec/glsl-1.50/execution/variable-indexing/vs-output-array-vec3-index-wr-before-gs spec/glsl-1.50/execution/variable-indexing/vs-output-array-float-index-wr-before-gs Fixes 80 dEQP tests with the NIR-vec4 backend in the following category: dEQP-GLES3.functional.ubo.* Reviewed-by: Francisco Jerez <[email protected]> Reviewed-by: Kenneth Graunke <[email protected]>

The specification seems to contradict itself - the main text says that only one fog application option may be specified, but then backpedals, indicating the intent is to disallow /contradictory/ flags. One of the issues suggests that specifying contradictory ones is stupid, but allowed, and only the last one should take effect.
