Kai Nacke ceb3b46490 PR16726: extend rol/ror matching ... C-like languages promote types like unsigned short to unsigned int before performing an arithmetic operation. Currently the rotate matcher in the DAGCombiner does not consider this situation. This commit extends the DAGCombiner in the way that the pattern (or (shl ([az]ext x), (*ext y)), (srl ([az]ext x), (*ext (sub 32, y)))) is folded into ([az]ext (rotl x, y)) The matching is restricted to aext and zext because in this cases the upper bits are either undefined or known. Test case is included. This fixes PR16726. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191049 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-19 23:00:28 +00:00
