* Fix test added in r236850 for OSX builders.James Y Knight2015-05-081-1/+1
| | | | | | | Need to specify triple so that llvm emits the asm syntax that the test expected. llvm-svn: 236855
* Fix alignment checks in MergeConsecutiveStores.James Y Knight2015-05-081-0/+68
1) check whether the alignment of the memory is sufficient for the *merged* store or load to be efficient. Not doing so can result in some ridiculously poor code generation, if merging creates a vector operation which must be aligned but isn't. 2) DON'T check that the alignment of each load/store is equal. If you're merging 2 4-byte stores, the first *might* have 8-byte alignment, but the second certainly will have 4-byte alignment. We do want to allow those to be merged. llvm-svn: 236850
