https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89280 --- Comment #8 from Jakub Jelinek --- Seems to work fine even if the dead returns_twice call is found later, e.g. on int a; void foo (void); __attribute__ ((returns_twice)) int bar (void); void baz (int, int); static inline void inl (int x) {

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89280 --- Comment #4 from Richard Biener --- The issue is that r8 () is a source of abnormal edges which makes the abnormal dispatcher reachable. I think the testcase becomes clearer when one uses setjmp instead of vfork since I'm not sure why we
