[BOLT] LongJmp pass causes clang-bolt buildbot timeout #71760

Open aaupov opened 10 months ago

aaupov commented 10 months ago

https://lab.llvm.org/buildbot/#/builders/276/builds/301 Buildbot kills the testing during BOLT optimizing Clang binary. When checked locally, it's the LongJmp pass that never finishes.

As discussed offline, we may not even need to run this pass since 128M range should be sufficient for Clang .text section.

Im also facing the same issue. Can you help me review this pull request?

Hi @aaupov! Probably could be closed?

I've changed aarch64-clang-bolt testing from mold to lld linker which doesn't cause that issue. It's still worth investigating.
