Nick Lewycky 5bf7f88ea2 Make the 'icmp pred trunc(ext(X)), CST --> icmp pred X, ext(trunc(CST))' ... transformation much more careful. Truncating binary '01' to '1' sounds like it's safe until you realize that it switched from positive to negative under a signed interpretation, and that depends on the icmp predicate. Also a few miscellaneous cleanups. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@97721 91177308-0d34-0410-b5e6-96231b3b80d8		2010-03-04 06:54:10 +00:00
