David Majnemer da449ec54b InstCombine: Optimize (1 << X) Pred CstP2 to X Pred Log2(CstP2) ... We may, after other optimizations, find ourselves with IR that looks like: %shl = shl i32 1, %y %cmp = icmp ult i32 %shl, 32 Instead, we should just compare the shift count: %cmp = icmp ult i32 %y, 5 llvm-svn: 185242		2013-06-28 23:42:03 +00:00
