--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> --- 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.
