From ae66c1fc9b50b1f51662edc9a2358069a2502fc3 Mon Sep 17 00:00:00 2001 From: Elena Zannoni Date: Wed, 15 Jan 2003 00:48:38 +0000 Subject: [PATCH] 2003-01-14 Elena Zannoni * breakpoint.c (until_break_command): Add new argument. Use it to decide whether to stop only at the current frame or not. * breakpoint.h (until_break_command): Update prototype. * infcmd.c (until_command): Add new argument to until_break_command call. (advance_command): New function. (_initialize_infcmd): Update help string for 'until' command. Add new 'advance' command. --- gdb/ChangeLog | 11 +++++++++++ gdb/breakpoint.c | 21 ++++++++++++++------- gdb/breakpoint.h | 2 +- gdb/infcmd.c | 41 ++++++++++++++++++++++++++++++++++++++--- 4 files changed, 64 insertions(+), 11 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 947e2bb005b..1279eb49c4e 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,14 @@ +2003-01-14 Elena Zannoni + + * breakpoint.c (until_break_command): Add new argument.
