Matt Arsenault f0a88dbaab LoadStoreVectorizer: Split even sized illegal chains properly ... Implement isLegalToVectorizeLoadChain for AMDGPU to avoid producing private address spaces accesses that will need to be split up later. This was doing the wrong thing in the case where the queried chain was an even number of elements. A possible <4 x i32> store was being split into store <2 x i32> store i32 store i32 rather than store <2 x i32> store <2 x i32> when legal. llvm-svn: 295933		2017-02-23 03:58:53 +00:00
