Local fix

  • N/A
    

Problem summary

  • The register allocator gets caught in a non-productive
    spill-rebuild graph cycle of the Briggs algorithm for condition
    registers because logical operations on condition registers did
    not use a new name for spilled register. This resulted in a
    broken live range but the pieces of the broken live range we
    still required the same register because the new live ranges
    used the same name.
    

Problem conclusion

  • Problem was fixed.
    

Temporary fix
