https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85397 --- Comment #2 from H.J. Lu --- Please take a look at hjl/cet/master branch at https://github.com/hjl-tools/gcc/tree/hjl/cet/master I replaced builtin_setjmp_setup and builtin_longjmp with save_stack_nonlocal and restore_stack_nonlocal to save and restore shadow stack to support both builtin setjmp/longjmp as well as non-local goto in nested functions.
