--- Comment #8 from Robin Dapp <rdapp at gcc dot gnu.org> --- While regtesting on aarch64 I saw a single test flip, gcc.dg/pr78213.c: FAIL: gcc.dg/pr78213.c (test for excess errors) Excess errors: cc1: warning: JSON tuning enables dispatch scheduling but 'dispatch_constraints' is not available; disabling dispatch scheduling This seems very unrelated but happens reproducibly with a bootstrapped compiler with the patch (and not without it or without bootstrap). Does this ring a bell for aarch64? I'll continue to investigate but certainly an odd issue.
