Evan Cheng	93a635c82c	It's not safe to fold (fptrunc (sqrt (fpext x))) to (sqrtf x) if there is another use of sqrt. rdar://9763193 ... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@135058 91177308-0d34-0410-b5e6-96231b3b80d8	2011-07-13 19:08:16 +00:00
Chris Lattner	979ed44feb	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). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@113260 91177308-0d34-0410-b5e6-96231b3b80d8	2010-09-07 20:01:38 +00:00
