From 31aceaef1cba910c84b81c78064d226fd10d8976 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Mon, 10 May 2021 12:13:36 -0400 Subject: [PATCH] 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.
