Now alternatively to the TargetOption.AllowFPOpFusion global flag, FMUL->FADD can also use the per operation FMF to allow fusion. The idea here is not to port everything to the new scheme (e.g. fused multiply-and-sub will be ported later) but that this work all the way from clang. The transformation is conditionalized on *both* the FADD and the FMUL having the FMF contract flag. Differential Revision: https://reviews.llvm.org/D31169 llvm-svn: 299096 |
