From 85df9457b72e4a198b4edfc908017612fca59509 Mon Sep 17 00:00:00 2001 From: Andrew Burgess Date: Thu, 2 Feb 2023 11:45:41 +0000 Subject: gdb/doc: extend the documentation for the 'handle' command The documentation for the 'handle' command does not cover all of the features of the command, and in one case, is just wrong. The user can specify 'all' as signal name, the documentation implies that this will change the behaviour of all signals, in reality, this changes all signals except SIGINT and SIGTRAP (the signals used by GDB). I've updated the docs to list this limitation. The 'handle' command also allows the user to specify multiple signals for a single command, e.g. 'handle SIGFPE SIGILL nostop pass print', however the documentation doesn't describe this, so I've updated the docs to describe this feature. --- gdb/doc/gdb.texinfo | 15 ++++++++------- 1 file changed, 8 insertions(+), 7 deletions(-) (limited to 'gdb/doc') diff --git a/gdb/doc/gdb.texinfo b/gdb/doc/gdb.texinfo index c90874a..eebb6dd 100644 --- a/gdb/doc/gdb.texinfo +++ b/gdb/doc/gdb.texinfo @@ -6760,13 +6760,14 @@ Set a catchpoint for the indicated signals. @xref{Set Catchpoints}, for details about this command. @kindex handle -@item handle @var{signal} @r{[}@var{keywords}@dots{}@r{]} -Change the way @value{GDBN} handles signal @var{signal}.
