* remote.c (remote_store_registers): Fix memset usage.
* std-regs.c (value_of_builtin_frame_reg): Ditto.
(value_of_builtin_frame_fp_reg): Ditto.
(value_of_builtin_frame_reg): Ditto.
Reported by: Dirk Engling
gdb: Add missing break statements
2004-05-21 Jim Blandy <j...@redhat.com>
* dwarf2expr.c (execute_stack_op): Add 'break' statements after
cases for DW_OP_div and DW_OP_shr. (Thanks to Reva Cuthbertson.)
GDB: Replace use of sprintf.
2005-03-17 Mark Kettenis <kette...@gnu.org>
* corelow.c (get_core_register_section): Replace usage of sprintf
and strcpy with xstrprintf and xstrdup.
