Arnold Schwaighofer e737018a86 DAGCombiner: Merge store/loads when we have extload/truncstores ... This is helps on architectures where i8,i16 are not legal but we have byte, and short loads/stores. Allowing us to merge copies like the one below on ARM. copy(char *a, char *b, int n) { do { int t0 = a[0]; int t1 = a[1]; b[0] = t0; b[1] = t1; radar://13536387 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178546 91177308-0d34-0410-b5e6-96231b3b80d8		2013-04-02 15:58:51 +00:00
