Andrew Trick f5bf687cf7 SLP vectorizer: Don't hoist vector extracts of phis. ... Extracts coming from phis were being hoisted, while all others were sunk to their uses. This was inconsistent and didn't seem to serve a purpose. Changing all extracts to be sunk to uses is a prerequisite for adding block frequency to the SLP vectorizer's cost model. I benchmarked the change in isolation (without block frequency). I only saw noise on x86 and some potentially significant improvements on ARM. No major regressions is good enough for me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@204699 91177308-0d34-0410-b5e6-96231b3b80d8		2014-03-25 02:18:47 +00:00
