Matt Arsenault	2aed6ca1d3	AMDGPU: Switch barrier intrinsics to using convergent ... noduplicate prevents unrolling of small loops that happen to have barriers in them. If a loop has a barrier in it, it is OK to duplicate it for the unroll. llvm-svn: 256075	2015-12-19 01:46:41 +00:00
Matt Arsenault	61001bbc03	AMDGPU: Make v2i64/v2f64 legal types. ... They can be loaded and stored, so count them as legal. This is mostly to fix a number of common cases for load/store merging. llvm-svn: 254086	2015-11-25 19:58:34 +00:00
Matt Arsenault	84db5d97b0	AMDGPU/SI: Fix read2 merging into a super register. ... If the read2 produced was supposed to be writing into a super register, it would use the wrong subregister indices. Fix this by inserting copies, so we only ever write to a vreg_64. Run the register coalescer again to clean this up, although this isn't ideal and often does result in an extra move. Also remove the assert that offset1 > offset0. There isn't a real reason to not allow this other than a minor convenience in the compiler, and it doesn't seem worth the effort of avoiding it. llvm-svn: 242174	2015-07-14 17:57:36 +00:00
