Thiago Jung Bauermann <bauerman@br.ibm.com> Implement support for PowerPC BookE masked watchpoints. gdb/ * NEWS: Mention masked watchpoint support. Create "Changed commands" section. * breakpoint.h (struct breakpoint_ops) <works_in_software_mode>: New method. Initialize to NULL in all existing breakpoint_ops instances. (struct breakpoint) <hw_wp_mask>: New field. * breakpoint.c (is_masked_watchpoint): Add prototype. (update_watchpoint): Don't set b->val for masked watchpoints. Call breakpoint's breakpoint_ops.works_in_software_mode if available. (watchpoints_triggered): Handle the case of a hardware masked watchpoint trigger. (watchpoint_check): Likewise. (works_in_software_mode_watchpoint): New function. (insert_masked_watchpoint, remove_masked_watchpoint) (resources_needed_masked_watchpoint) (works_in_software_mode_masked_watchpoint, print_it_masked_watchpoint) (print_one_detail_masked_watchpoint, print_mention_masked_watchpoint) (print_recreate_masked_watchpoint, is_masked_watchpoint): New functions. (masked_watchpoint_breakpoint_ops): New structure. (watch_command_1): Check for the existence of the `mask' parameter. Set b->ops according to the type of hardware watchpoint being created. * ppc-linux-nat.c (ppc_linux_insert_mask_watchpoint) (ppc_linux_remove_mask_watchpoint) (ppc_linux_masked_watch_num_registers): New functions. (_initialize_ppc_linux_nat): Initialize to_insert_mask_watchpoint, to_remove_mask_watchpoint and to_masked_watch_num_registers. * target.c (update_current_target): Mention to_insert_mask_watchpoint, to_remove_mask_watchpoint, and to_masked_watch_num_registers. (target_insert_mask_watchpoint, target_remove_mask_watchpoint) (target_masked_watch_num_registers): New functions. * target.h (struct target_ops) <to_insert_mask_watchpoint>, <to_remove_mask_watchpoint>, <to_masked_watch_num_registers>: New methods. (target_insert_mask_watchpoint, target_remove_mask_watchpoint) (target_masked_watch_num_registers): Add prototypes. gdb/doc/ * gdb.texinfo (Set Watchpoints): Document mask parameter. (PowerPC Embedded): Mention support of masked watchpoints.
