* i965/vec4: Fix broken saturate mask check in copy propagation.Francisco Jerez2015-03-231-4/+11
| | | | | | | | | | | try_copy_propagate() was checking the bit of the saturate mask for the arg-th component of the source to decide whether the whole source should be saturated (WTF?). We need to swizzle the original saturate mask and check that for all enabled channels the saturate flag is either set or unset, as we cannot saturate a subset of destination components only.

| | | | | | | | | This reverts commit 0dfec59a2785cf7a87ee5128889ecebe810b611b. The change prevented propagation of copies with the saturate flag set, making the whole saturate mask tracking completely useless. A proper fix follows. Reviewed-by: Abdiel Janulgue <[email protected]>

* i965/vec4: Improve src_reg/dst_reg conversion constructors.Francisco Jerez2015-03-231-26/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This simplifies the src_reg/dst_reg conversion constructors using the swizzle utils introduced in a previous patch. It also makes them more useful by changing their semantics slightly: dst_reg(src_reg) used to set the writemask to XYZW if the src_reg swizzle was anything other than XXXX, which was almost certainly not what the caller intended if the swizzle was non-trivial. After this patch the same components that are present in the swizzle will be enabled in the resulting writemask. src_reg(dst_reg) used to set the first components of the swizzle to the enabled components of the writemask and then replicate the last enabled component to fill the swizzle, which, in cases where the writemask didn't have exactly the first n components set, would in general not be compatible with the original dst_reg. E.g.: | ADD(tmp, src_reg(tmp), src_reg(1)); would *not* do what one would expect (add one to each of the enabled components of tmp) if tmp didn't have a writemask of the described form (e.g. YZ, YW, XZW would all fail). This pattern actually occurs in many different places in the VEC4 back-end, it's a wonder that it hasn't caused piglit failures until now. After this patch src_reg(dst_reg) will construct a swizzle with each enabled component at its natural position (e.g. Y at the second position, Z at the third, and so on). The resulting swizzle will behave like the identity when used in any instruction with the original writemask. I've manually verified that *none* of the callers of both conversion constructors were relying on the previous broken semantics. There are no piglit regressions on any generation.

| | | | | | | | | | It could be objected that swizzle_for_size() is "faster" than brw_swizzle_for_size(). It's not measurably better in any reasonable CPU-bound benchmark on VLV according to the Finnish benchmarking system (including the SynMark2 DrvShComp shader compilation benchmark).
