Summary: In addMustTailToCoroResumes, we set musttail on those resume instructions that are followed by a ret instruction. This is done by simplifyTerminatorLeadingToRet which replace a sequence of branches leading to a ret with a clone of the ret. However it forgets to remove corresponding PHI values that come from basic block of replaced branch, and may cause jumpthreading pass hangs (https://bugs.llvm.org/show_bug.cgi?id=43720) This patch fix this issue Test Plan: cppcoro library with O3+flto check-llvm Reviewers: modocache, GorNishanov, lewissbaker Reviewed By: modocache Subscribers: mehdi_amini, EricWF, hiraditya, dexonsmith, jfb, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D71826 Patch by junparser (JunMa)! |
