From e64d9b3dea5a099bcb97984fed54ab14f967b02f Mon Sep 17 00:00:00 2001 From: Martin Hunt Date: Wed, 3 Jul 2002 20:23:04 +0000 Subject: [PATCH] 2002-07-03 Martin M. Hunt * varobj.c (struct varobj_root): Change frame from CORE_ADDR to struct frame_id. (varobj_create): Store frame_id for root. (varobj_gen_name): Use xasprintf. (varobj_update): Save and restore frame using get_frame_id() and frame_find_by_id(). (create_child): Use xasprintf. (new_root_variable): Initialize frame_id. (c_name_of_child): Use xasprintf. Call find_frame_by_id(). (c_value_of_variable): Use xasprintf. Move mem_fileopen call to prevent memory leak. --- gdb/ChangeLog | 15 +++++++++++ gdb/varobj.c | 71 ++++++++++++++++++++------------------------------- 2 files changed, 43 insertions(+), 43 deletions(-) diff --git a/gdb/ChangeLog b/gdb/ChangeLog index 2c3e57e60a6..928bf91ea43 100644 --- a/gdb/ChangeLog +++ b/gdb/ChangeLog @@ -1,3 +1,18 @@ +2002-07-03 Martin M.
