This is very related to the bug fixed in r174431. The problem is that SelectionDAG does not include alignment in the uniquing of loads and stores. When an otherwise no-op DAGCombine would increase the alignment of a load or store, the original node would be returned (with the alignment increased), which would cause the node not to be processed by any further DAGCombines. I don't have a direct testcase for this that manifests on an in-tree target, but I did see some noise in the tests for other targets and have updated them for it. llvm-svn: 232780
