Separate out ANSI-standard signals
This commit reorders various pieces of code to separate ANSI-standard signals from other signals that need checking. Comments are added to document this, and to document the ordering of the signals. gdb/ 2014-06-09 Gary Benson <gbenson@redhat.com> * common/signals.c (gdb_signal_from_host): Reorder to separate the always-available ANSI-standard signals from the signals that require checking. (do_gdb_signal_to_host): Likewise. * proc-events.c (signal_table): Likewise. gdb/testsuite/ 2014-06-09 Gary Benson <gbenson@redhat.com> * gdb.base/sigall.c [Functions to send signals]: Reorder to separate the always-available ANSI-standard signals from the signals that require checking. (main): Likewise. * gdb.reverse/sigall-reverse.c [Functions to send signals]: Likewise. (main): Likewise.
