260 These probes are used to signal calls to @code{setjmp}, @code{sigsetjmp},
261 @code{longjmp} or @code{siglongjmp}.
264 This probe is triggered whenever @code{setjmp} or @code{sigsetjmp} is
265 called.  Argument @var{$arg1} is a pointer to the @code{jmp_buf}
266 passed as the first argument of @code{setjmp} or @code{sigsetjmp},

290 The @code{longjmp_target} probe is triggered at a point where the
291 registers have been restored to the values in the @code{jmp_buf} and
292 unwinding will show a call stack including the caller of @code{setjmp}
293 or @code{sigsetjmp}.
