--- Comment #10 from Sam James <sjames at gcc dot gnu.org> --- (In reply to Tamar Christina from comment #8) > Hmm curious, does it work for you with --with-build-config='bootstrap-O3' > that's how I tested it before Will have a look. I'll try ignore the bootstrap failure and build userland stuff now so we can get some other cases if any. Did you have -march=<some ISA with good enough vector instructions> too? I imagine bare '-O2' or '-O3' will be ok on amd64. I built with the above configure args but also: 1. make -j32 -l32 'STAGE1_CFLAGS=-O3 -march=znver2 -pipe' 'BOOT_CFLAGS=-O3 -march=znver2 -pipe' ... 2. CFLAGS=... exported in the env
