--- Comment #3 from Andreas Krebbel <krebbel at gcc dot gnu.org> --- (In reply to Vladimir Makarov from comment #2) Thanks! Btw. the Ada and Java bootstraps started failing with enabling LRA for S/390 (also without --with-arch=...). I'll wait for a patch for this PR before having a closer look. Perhaps the fails are related?!
