Given the frequency throttling\nconcerns with using wider vector ops, an extra extract to reduce vector\nwidth is the right trade-off at this level of codegen.\n\nDifferential Revision: https://reviews.llvm.org/D54392","distinct":true,"url":"https://api.github.com/repos/llvm-project/llvm-project-20170507/commits/7fbc33c765067c5ae533eedaf45e170955913d21"}]}
