Tim Northover f5e4c28c3f Generic: Make isMask_N and isShiftedMask_N consistent over 0 ... Previously, isMask_N returned false for 0 but isShiftedMask_N returned true. Almost all uses are for pattern matching bitfield operations in the backends, and expect false (this was discovered because of AArch64's copy of this logic). Unfortunately, I couldn't put together a small non-fragile test for this. The nature of the bitfield operations means that this edge case is only really triggered for nodes like "(and N, 0)", which the DAG combiner is usually very good at folding away before they get to this stage. rdar://20501377 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@234659 91177308-0d34-0410-b5e6-96231b3b80d8		2015-04-10 22:58:48 +00:00
