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	4bf43d4e68	AMDGPU: Handle i64->v2i32 loads/stores in PreprocessISelDAG This fixes a select error when the i64 source was also bitcasted to v2i32 in the original source. Instead of awkwardly trying to select the modified source value and the store, replace before isel begins. Uses a worklist to avoid possible problems from mutating the DAG, although it seems to work OK without it. llvm-svn: 248589	2015-09-25 17:27:08 +00:00

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.

AMDGPU: Handle i64->v2i32 loads/stores in PreprocessISelDAG

This fixes a select error when the i64 source was also
bitcasted to v2i32 in the original source.

Instead of awkwardly trying to select the modified source value and
the store, replace before isel begins.

Uses a worklist to avoid possible problems from mutating the DAG,
although it seems to work OK without it.
