Sanjay Patel 2a43c2e32f [LoopVectorize] propagate fast-math-flags from induction instructions ... This code assumed that FP math was only permissable if it was fully "fast", so it hard-coded "fast" when creating new instructions. The underlying code already allows matching recurrences/reductions that are only "reassoc", so this change should prevent the potential miscompile seen in the test diffs (we created "fast" ops even though none existed in the original code). I don't know if we need to create the temporary IRBuilder objects used here, so that could be follow-up clean-up. There's an open question about whether we should require "nsz" in addition to "reassoc" here. InstCombine uses that combo for its reassociative folds, but I think codegen is not as strict.		2021-03-04 17:21:32 -05:00
