Arnold Schwaighofer 074e489dbc SLPVectorizer: Handle more horizontal reductions (disabled) ... Match reductions starting at binary operation feeding into a phi. The code handles trees like r += v1 + v2 + v3 ... and r += v1 r += v2 ... and r *= v1 + v2 + ... We currently only handle associative operations (add, fadd fast). The code can now also handle reductions feeding into stores. a[i] = v1 + v2 + v3 + ... The code is currently disabled behind the flag "-slp-vectorize-hor". The cost model for most architectures is not there yet. I found one opportunity of a horizontal reduction feeding a phi in TSVC (LoopRerolling-flt) and there are several opportunities where reductions feed into stores. radar://14607682 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191108 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-20 21:18:20 +00:00
