When a call site with noalias metadata is inlined, that metadata can be propagated directly to the inlined instructions (only those that might access memory because it is not useful on the others). Prior to inlining, the noalias metadata could express that a call would not alias with some other memory access, which implies that no instruction within that called function would alias. By propagating the metadata to the inlined instructions, we preserve that knowledge. This should complete the enhancements requested in PR20500. llvm-svn: 215676 |
