Evan Cheng	ba4a50f10c	It's not safe to fold (fptrunc (sqrt (fpext x))) to (sqrtf x) if there is another use of sqrt. rdar://9763193 ... llvm-svn: 135058	2011-07-13 19:08:16 +00:00
Chris Lattner	a58a97dafc	Fix a serious performance regression introduced by r108687 on linux: ... turning (fptrunc (sqrt (fpext x))) -> (sqrtf x) is great, but we have to delete the original sqrt as well. Not doing so causes us to do two sqrt's when building with -fmath-errno (the default on linux). llvm-svn: 113260	2010-09-07 20:01:38 +00:00
Chris Lattner	f2534b401f	rename test. ... llvm-svn: 113257	2010-09-07 19:57:06 +00:00
