gdb, gdbserver: make status_to_str display the signal name
I was looking at some "set debug lin-lwp" logs, and saw that a thread
received the "Child exited" signal. It took me a moment to realize that
this was SIGCHLD. I then thought that it would be nice for
status_to_str to show the signal name (SIGCHLD) in addition to the
description "Child exited", since people are much more used to referring
to signals using their names.
Fortunately, libiberty contains a handy function to get the signal name
from the signal number, strsigno, use that.
The output of "set debug lin-lwp" now looks like:
[linux-nat] linux_nat_wait_1: waitpid 1209631 received SIGTRAP - Trace/breakpoint trap (stopped)
gdb/ChangeLog:
* nat/linux-waitpid.c (status_to_str): Show signal name.
