--- Comment #9 from Sam James <sjames at gcc dot gnu.org> --- OK, reproduced with: ``` $ ~/git/gcc/configure --prefix=/usr --with-build-config="bootstrap-lto bootstrap-O3" BOOT_CFLAGS="-O3 -march=znver2" BOOT_CXXFLAGS="-O3 -march=znver2" $ make profiledbootstrap -j$(nproc) -l$(nproc) ``` Will see if I can remove more.
