STINNER Victor added the comment: +#define Py_UNREACHABLE() abort()
Using such macro, I don't think that __builtin_unreachable() is useful. https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html Another use for __builtin_unreachable is following a call a function that never returns but that is not declared __attribute__((noreturn)), as in this example: (...) function_that_never_returns (); __builtin_unreachable (); I expect abort() to be annotated with __attribute__((noreturn)) on the C library used GCC. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31338> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
