Thiago Jung Bauermann <bauerman@br.ibm.com> Support for hw accelerated condition watchpoints in booke powerpc. * breakpoint.c (fetch_watchpoint_value): Rename to fetch_subexp_value and move to eval.c. Change callers. (insert_bp_location): Pass watchpoint condition in target_insert_watchpoint. (remove_breakpoint_1) Pass watchpoint condition in target_remove_watchpoint. (watchpoint_locations_match): Call target_can_accel_watchpoint_condition. * eval.c: Include wrapper.h. (fetch_subexp_value): Moved from breakpoint.c. * ppc-linux-nat.c (ppc_linux_region_ok_for_hw_watchpoint): Formatting fix. (can_use_watchpoint_cond_accel): New function. (calculate_dvc): Likewise. (num_memory_accesses): Likewise. (check_condition): Likewise. (ppc_linux_can_accel_watchpoint_condition): Likewise (ppc_linux_insert_watchpoint): Call can_use_watchpoint_cond_accel, check_condition and calculate_dvc. (ppc_linux_remove_watchpoint): Likewise. (_initialize_ppc_linux_nat): Set to_can_accel_watchpoint_condition to ppc_linux_can_accel_watchpoint_condition * target.c (debug_to_insert_watchpoint): Add argument for watchpoint condition. (debug_to_remove_watchpoint): Likewise. (debug_to_can_accel_watchpoint_condition): New function. (update_current_target): Set to_can_accel_watchpoint_condition. (setup_target_debug): Set to_can_accel_watchpoint_condition. * target.h: Add opaque declaration for struct expression. (struct target_ops) <to_insert_watchpoint>, <to_remove_watchpoint>: Add new arguments to pass the watchpoint <to_can_accel_watchpoint_condition>: New member. condition. Update all callers and implementations. (target_can_accel_watchpoint_condition): New macro. * value.c (free_value_chain): New function. * value.h (fetch_subexp_value): New prototype. (free_value_chain): Likewise.
