From 23e1f78b70ea8f91350d94e7d255515f2d9c9b9b Mon Sep 17 00:00:00 2001 From: Martin Hunt Date: Mon, 5 Oct 1998 07:32:59 +0000 Subject: [PATCH] Mon Oct 5 00:34:00 1998 Martin M. Hunt * gdbtk-cmds.c (gdb_set_bp_addr): New command. Sets a breakpoint at an address. Use this instead of gdb_cmd "break" because the syntax of the break command is broken and doesn't allow you to create a thread-specific BP at an address. Also this is faster. --- gdb/ChangeLog-gdbtk | 8 +++++ gdb/gdbtk-cmds.c | 87 +++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 95 insertions(+) diff --git a/gdb/ChangeLog-gdbtk b/gdb/ChangeLog-gdbtk index 8f5571e..98c12cf 100644 --- a/gdb/ChangeLog-gdbtk +++ b/gdb/ChangeLog-gdbtk @@ -1,3 +1,11 @@ +Mon Oct 5 00:34:00 1998 Martin M.
