Shuxin Yang a0c9939873 Perform factorization as a last resort of unsafe fadd/fsub simplification. ... Rules include: 1)1 x*y +/- x*z => x*(y +/- z) (the order of operands dosen't matter) 2) y/x +/- z/x => (y +/- z)/x The transformation is disabled if the new add/sub expr "y +/- z" is a denormal/naz/inifinity. rdar://12911472 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@177088 91177308-0d34-0410-b5e6-96231b3b80d8		2013-03-14 18:08:26 +00:00
