* | [LV] Strip wrap flags from vectorized reductions | Ayal Zaks | 2019-12-20 | 1 | -0/+58 |
A sequence of additions or multiplications that is known not to wrap, may wrap if it's order is changed (i.e., reassociated). Therefore when vectorizing integer sum or product reductions, their no-wrap flags need to be removed. Fixes PR43828 Patch by Denis Antrushin Differential Revision: https://reviews.llvm.org/D69563 |
