I was going to say manual/probes.texi but I see the longjmp probes
aren't documented.
Currently gdb only uses the third argument, which is the target PC.
Marcus> Do we need probes in setjmp aswell?
I think it's nice for users if the probes are the same across ports.
That said, gdb itself only uses the longjmp and rtld probes from glibc.
gdb users (or SystemTap users) can refer to the other probes though.
