[PATCH] D17123: AMDGPU: Handle splitting 64-bit private accesses when necessary

[Matt Arsenault via llvm-commits]

arsenm added a comment.

I'm going to try moving this into the lowering and try to fix the problem with ExpandUnalignedLoad, or do this in a post-legalize target dag combine. The problem with this is the pointer add for the split is not folded into the previous pointer add, which sometimes breaks the addressing mode matching
