Dmitri Gribenko	b137c9e551	Tests: rewrite 'opt ... %s' to 'opt ... < %s' so that opt does not emit a ModuleID This is done to avoid odd test failures, like the one fixed in r171243. llvm-svn: 171246	2012-12-30 01:28:40 +00:00
Nick Lewycky	1a7ed5868b	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. llvm-svn: 97721	2010-03-04 06:54:10 +00:00

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.
