Chris Lattner 01ceb99a05 Transform: "icmp eq (trunc (lshr(X, cst1)), cst" to "icmp (and X, mask), cst" ... when X has multiple uses. This is useful for exposing secondary optimizations, but the X86 backend isn't ready for this when X has a single use. For example, this can disable load folding. This is inching towards resolving PR6627. llvm-svn: 130238		2011-04-26 20:18:20 +00:00
