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.
