We currently return 4 for stackmaps and patchpoints, which is very optimistic and can in rare cases cause the branch relaxation pass to fail to relax certain branches. This patch causes getInstSizeInBytes to return a pessimistic estimate of the size as the number of bytes requested in the stackmap/patchpoint. In the future, we could provide a more accurate estimate by sharing some of the logic in AArch64::LowerSTACKMAP/PATCHPOINT. Fixes part of https://llvm.org/bugs/show_bug.cgi?id=28750 Differential Revision: https://reviews.llvm.org/D24073 llvm-svn: 281301 |
