Make BOLT as stable feature #101525
Description
Using a BOLT still not guarantee the unexpected behavior changes.
For example, I observed that #53093 is raised if the binary is optimized by BOLT.
We can reduce several too aggressive optimization.
- Optimizing BOLT flags #128514
- Choose the APIs that should not be optimized BOLT (e.g -skip-funcs)
- Update libregrtest.utils.get_build_info()
- Update
make testto work correctly (Should skip the BOLT phase if the binary is already BOLTed) - Define minimum LLVM version
- Enhance the BOLT build process #101282
- Test BOLT builds in CI #128515
