Jakob Stoklund Olesen 9571cb56c5 Don't PRE compares. ... CodeGenPrepare sinks compare instructions down to their uses to prevent live flags and predicate registers across basic blocks. PRE of a compare instruction prevents that, forcing the i1 compare result into a general purpose register. That is usually more expensive than the redundant compare PRE was trying to eliminate in the first place. llvm-svn: 153657		2012-03-29 17:22:39 +00:00
