--- Comment #12 from Gaius Mulley <gaius at gcc dot gnu.org> --- Created attachment 55391 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=55391&action=edit Proposed fix (addendum) I wonder whether this modification to Jakub's patch might help? m2/gm2-compiler-boot/m2flex.o is needed by cc1gm2 whereas m2/gm2-compiler/m2flex.o is required by m2/stage2/cc1gm2 (only built in maintainer to allow debugging via m2 sources rather than the translated to C++ sources. Also moved the unused (debugging rule) c-family/m2pp.o into Make-maintainer.o (currently being bootstrapped on x86_64 make -j 12) and (ppc64le make -j 128)
