From 6eaaf48b1c3ff871cdcd180c172a72271fe29588 Mon Sep 17 00:00:00 2001 From: Eli Zaretskii Date: Fri, 12 Apr 2013 08:57:07 +0000 Subject: [PATCH] Implement a new command to show GDB build-time configuration parameters. * top.c (print_gdb_configuration): New function, displays the details about GDB configure-time parameters. (print_gdb_version): Mention "show configuration". * cli/cli-cmds.c (show_configuration): New function. (_initialize_cli_cmds): Add the "show configuration" command. * main.c (captured_main) : New static var. : Use it. If --configuration was given, call print_gdb_configuration. * doc/gdb.texinfo (Mode Options): Document '-configuration'. (Help): Document "show configuration". (Bug Reporting): Add requirements to include the configuration details in bug reports. --- gdb/ChangeLog | 13 +++++++ gdb/cli/cli-cmds.c | 9 +++++ gdb/doc/ChangeLog | 7 ++++ gdb/doc/gdb.texinfo | 23 +++++++++++- gdb/main.c | 16 +++++++- gdb/top.c | 90 ++++++++++++++++++++++++++++++++++++++++++++- gdb/top.h | 1 + 7 files changed, 154 insertions(+), 5 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index eaf9d042883..c903714cdfd 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,16 @@ +2013-04-12 Eli Zaretskii + + * top.c (print_gdb_configuration): New function, displays the + details about GDB configure-time parameters. + (print_gdb_version): Mention "show configuration". + + * cli/cli-cmds.c (show_configuration): New function. + (_initialize_cli_cmds): Add the "show configuration" command. + + * main.c (captured_main) : New static var. + : Use it. + If --configuration was given, call print_gdb_configuration. + 2013-04-11 Jan Kratochvil Pedro Alves diff --git a/gdb/cli/cli-cmds.c b/gdb/cli/cli-cmds.c index c4721bdf125..a5b2572d747 100644 --- a/gdb/cli/cli-cmds.c +++ b/gdb/cli/cli-cmds.c @@ -314,6 +314,12 @@ show_version (char *args, int from_tty) printf_filtered ("\n"); } +static void +show_configuration (char *args, int from_tty) +{ + print_gdb_configuration (gdb_stdout); +} + /* Handle the quit command. */ void @@ -1756,6 +1762,9 @@ the previous command number shown."), add_cmd ("version", no_set_class, show_version, _("Show what version of GDB this is."), &showlist); + add_cmd ("configuration", no_set_class, show_configuration, + _("Show how GDB was configured at build time."), &showlist); + /* If target is open when baud changes, it doesn't take effect until the next open (I think, not sure). */ add_setshow_zinteger_cmd ("remotebaud", no_class, &baud_rate, _("\ diff --git a/gdb/doc/ChangeLog b/gdb/doc/ChangeLog index d62a5a69c40..186e3d7d183 100644 --- a/gdb/doc/ChangeLog +++ b/gdb/doc/ChangeLog @@ -1,3 +1,10 @@ +2013-04-12 Eli Zaretskii + + * gdb.texinfo (Mode Options): Document '-configuration'. + (Help): Document "show configuration". + (Bug Reporting): Add requirements to include the configuration + details in bug reports. + 2013-04-11 Jan Kratochvil * Makefile.in (MAN1S): Add gcore.1. diff --git a/gdb/doc/gdb.texinfo b/gdb/doc/gdb.texinfo index 97d88ec6c31..fa37b8212f0 100644 --- a/gdb/doc/gdb.texinfo +++ b/gdb/doc/gdb.texinfo @@ -1268,6 +1268,12 @@ memory usage after it completes each command and returns to the prompt.
