--- Comment #2 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
-- Built-in Function: void __builtin_longjmp (intptr_t *BUF, int VAL)
This function restores the stack context in BUF, saved by a
previous call to `__builtin_setjmp'. After `__builtin_longjmp' is
finished, the program resumes execution as if the matching
`__builtin_setjmp' returns the value VAL, which must be 1.
Because `__builtin_longjmp' depends on the function return
mechanism to restore the stack context, it cannot be called from
the same function calling `__builtin_setjmp' to initialize BUF.
It can only be called from a function called (directly or
indirectly) from the function calling `__builtin_setjmp'.
