Shuxin Yang 3a7ca6ec87 [Fast-math] Disable "(C1/X)*C2 => (C1*C2)/X" if C1/X has multiple uses. ... If "C1/X" were having multiple uses, the only benefit of this transformation is to potentially shorten critical path. But it is at the cost of instroducing additional div. The additional div may or may not incur cost depending on how div is implemented. If it is implemented using Newton–Raphson iteration, it dosen't seem to incur any cost (FIXME). However, if the div blocks the entire pipeline, that sounds to be pretty expensive. Let CodeGen to take care this transformation. This patch sees 6% on a benchmark. rdar://15032743 llvm-svn: 191037		2013-09-19 21:13:46 +00:00
