--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Jakub Jelinek from comment #7) > Just tried it on godbolt and seems clang just silently doesn't tail call it. > That is IMHO worse behavior than erroring on that out. Sorry, ignore this, PEBKAC, I've used [[gnu::musttail]] attribute in the godbolt case instead of [[clang::musttail]]. With [[clang::musttail]] they actually emit a copy of the sanitizer epilogue sequence right before the tail call, and we should do that too.
