--- Comment #9 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
A (potentially simpler) alternative is to use sequential builds (make without
-j) and bisect by index of compiled source file, i.e. have a wrapper script
around gcc that uses some global counter to pass -mno-bmi to first N compiler
invocations.
