Chris Lattner 3bf6815556 enhance x-(-A) -> x+A to preserve NUW/NSW. ... Use the presence of NSW/NUW to fold "icmp (x+cst), x" to a constant in cases where it would otherwise be undefined behavior. Surprisingly (to me at least), this triggers hundreds of the times in a few benchmarks: lencode, ldecode, and 466.h264ref seem to *really* like this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@91812 91177308-0d34-0410-b5e6-96231b3b80d8		2009-12-21 04:04:05 +00:00
