From: Tankut Baris Aktemur Date: Thu, 6 May 2021 08:13:06 +0000 (+0200) Subject: gdb/mi: add a '--force-condition' flag to the '-break-insert' cmd X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=10e578d7e00d74033ded0443422ffc509390a912;p=binutils-gdb.git gdb/mi: add a '--force-condition' flag to the '-break-insert' cmd Add a '--force-condition' flag to the '-break-insert' command to be able to force conditions. Because the '-dprintf-insert' command uses the same mechanism as the '-break-insert' command, it obtains the '--force-condition' flag, too. gdb/ChangeLog: 2021-05-06 Tankut Baris Aktemur * mi/mi-cmd-break.c (mi_cmd_break_insert_1): Recognize the '--force-condition' flag to force the condition in the '-break-insert' and '-dprintf-insert' commands. * NEWS: Mention the change. gdb/testsuite/ChangeLog: 2021-05-06 Tankut Baris Aktemur * gdb.mi/mi-break.exp (test_forced_conditions): New proc that is called by the test. gdb/doc/ChangeLog: 2021-05-06 Tankut Baris Aktemur * gdb.texinfo (GDB/MI Breakpoint Commands): Mention the '--force-condition' flag of the '-break-insert' and '-dprintf-insert' commands. --- diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 674817cc1b6..87f366c4b68 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,10 @@ +2021-05-06 Tankut Baris Aktemur + + * mi/mi-cmd-break.c (mi_cmd_break_insert_1): Recognize the + '--force-condition' flag to force the condition in the + '-break-insert' and '-dprintf-insert' commands. + * NEWS: Mention the change. + 2021-05-04 Tom de Vries PR guile/27806 diff --git a/gdb/NEWS b/gdb/NEWS index 19cb444e7fe..a814b41315d 100644 --- a/gdb/NEWS +++ b/gdb/NEWS @@ -31,6 +31,14 @@ equivalent of the CLI's "break -qualified" and "dprintf -qualified". + ** '-break-insert --force-condition' and '-dprintf-insert --force-condition' + + The MI -break-insert and -dprintf-insert commands now support a + '--force-condition' flag to forcibly define a condition even when + the condition is invalid at all locations of the breakpoint.
