Richard Biener <rguenth at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2024-10-22 CC| |rguenth at gcc dot gnu.org Ever confirmed|0 |1 --- Comment #6 from Richard Biener <rguenth at gcc dot gnu.org> --- I think we should not preserve side-effects of gcc_assert, the define with __builtin_unreachable is "broken" in that way, I'm not sure why we decided to introduce that variant? gcc_assert should be consistent with gcc_checking_assert and the latter uses #if CHECKING_P #define gcc_checking_assert(EXPR) gcc_assert (EXPR) #else /* N.B.: in release build EXPR is not evaluated. */ #define gcc_checking_assert(EXPR) ((void)(0 && (EXPR))) #endif The original desired behavior (not evaluate side-effects) is consistent with assert(3).
