This patch adds a new convenience variable called "$_exitsignal", which will hold the signal number when the inferior terminates due to the uncaught signal. I've made modifications on infrun.c:handle_inferior_event such that $_exitcode gets cleared when the inferior signalled, and vice-versa. This assumption was made because the variables are mutually exclusive, i.e., when the inferior terminates because of an uncaught signal it is not possible for it to return. I have also made modifications such that when a corefile is loaded, $_exitsignal gets set to the uncaught signal that "killed" the inferior, and $_exitcode is cleared. The patch also adds a NEWS entry, documentation bits, and a testcase. The documentation entry explains how to use $_exitsignal and $_exitcode in a GDB script, by making use of the new $_isvoid convenience function. gdb/ 2013-10-06 Sergio Durigan Junior <sergiodj@redhat.com> * NEWS: Mention new convenience variable $_exitsignal. * corelow.c (core_open): Reset exit convenience variables.
