Summary: We teach alias analysis that invariant.start is readonly. This helps with GVN and memcopy optimizations that currently treat. invariant.start as a clobber. We need to treat this as readonly, so that DSE does not incorrectly remove stores prior to the invariant.start Reviewers: sanjoy, reames, majnemer, dberlin Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D23214 llvm-svn: 278138 |
