[PATCH 18/26] -Wpointer-sign: bookmarks.
- From: Pedro Alves <palves at redhat dot com>
- To: gdb-patches at sourceware dot org
- Date: Fri, 12 Apr 2013 00:01:08 +0100
- Subject: [PATCH 18/26] -Wpointer-sign: bookmarks.
- References: <20130411225847 dot 16791 dot 29283 dot stgit at brno dot lan>
Bookmarks are opaque to the core code -- by design, the target is free
to use any sort of blob as bookmark identifier.
The record target chooses to use strings for bookmarks. This adds
casts following that direction, fixing -Wpointer-sign warnings.

* record-full.c (record_full_get_bookmark): Change local 'ret'
type to char * and add cast to gdb_byte *.
(record_full_goto_bookmark): Handle 'bookmark' argument as a
string.
* reverse.c (goto_bookmark_command): Add casts to gdb_byte *.
