Hello guys,

This is the patch that modifies the architecture-independent files.  It is 
responsible for the implementation of the new commands (such as hbreak-range 
and watch-range), and the logic that handles the new types of hardware 
breakpoints/watchpoints.

Regards,

gdb/ChangeLog:

2009-16-12  Sergio Durigan Junior  <sergiodj@linux.vnet.ibm.com>

	* breakpoint.c (breakpoint_address_match_range): New function.
	(update_watchpoint): Added variables to save/restore new fields
	for the new types of hardware breakpoints/watchpoints.  Disabled
	watchpoints before checking the used count.  Handled the case when
	the hardware supports the acceleration of the watchpoint's condition
	evaluation.
	(insert_bp_location): Calling the correct insertion method according
	to the type of the hardware watchpoint.
	(remove_breakpoint_1): Calling the correct deletion method according
	to the type of the hardware watchpoint.
	(print_it_typical): Handling the various cases when the new types of
	hardware breakpoint/watchpoint are going to be printed.
	(watchpoints_triggered): Handling the triggering of a hardware masked
	watchpoint.
	(value_equal_watchpoint): New function.
	(watchpoint_check): Calling the correct comparison function for
	watchpoints.  Handling the case of a hardware mased watchpoint
	trigger.
	(bpstat_check_location): Handling the case of a hardware ranged
	watchpoint.
	(bpstat_check_breakpoint_conditions): Handling the case of a hardware
	watchpoint with a condition begin hardware-accelerated.
	(print_one_breakpoint_location): Handling the case of a hardware
	ranged watchpoint.
	(breakpoint_1): Ditto.
	(set_raw_breakpoint_without_location): Setting the flag to zero.
	(set_raw_breakpoint): Setting the range to zero.
	(hw_breakpoint_used_count): Added a call to target-specific function
	that will tell how many extra slots a hardware breakpoint needs.
	(hw_watchpoint_used_count): Ditto, for hardware watchpoints.
	(mention): Handling the case when we need to mention special types
	of hardware breakpoints/watchpoints.
	(watch_command_1): Added a routine to check for the existence of the
	`mask' parameter when the user creates a watchpoint.  Handling the
	creation of special types of hardware watchpoints (masked and
	hardware-accelerated condition).
	(can_use_hardware_watchpoint): Added code to check if the memory
	that is going to be watched is big, i.e., it needs a hardware ranged
	watchpoint.
	(watch_range_command_1): New function.
	(watch_range_command): Ditto.
	(awatch_range_command): Ditto.
	(rwatch_range_command): Ditto.
	(hbreak_range_command): Ditto.
	(update_breakpoint_locations):  Handling the case of a hardware
	watchpoint with a condition begin hardware-accelerated.
	(exp_is_address_p): New function.
	(exp_is_var_p): Ditto.
	(cond_is_address_equal_literal_p): Ditto.
	(cond_is_var_equal_literal_p): Ditto.
	(get_var_address): Ditto.
	(default_watch_address_if_var_equal_literal_p): Ditto.
	(default_watch_var_if_address_equal_literal_p): Ditto.
	(default_watch_var_if_var_equal_literal_p): Ditto.
	(default_watch_address_if_address_equal_literal_p): Ditto.
	
	* breakpoint.h (struct bp_target_info) <length>: New field.
	(struct bp_location) <cond_hw_accel>, <cond_hw_addr>,
	<ranged_hw_bp_length>, <hw_wp_mask>: New fields.
	(enum hw_point_flag): New.
	(struct breakpoint) <hw_point_flag>: New field.
	(default_watch_address_if_address_equal_literal_p): Declaring.
	(default_watch_var_if_var_equal_literal_p): Ditto.
	(default_watch_address_if_var_equal_literal_p): Ditto.
	(default_watch_var_if_address_equal_literal_p): Ditto.

	* findcmd.c (parse_addr_range): New function.
	(parse_find_args): Calling `parse_addr_range'.

	* ui-out.c (ui_out_field_range_core_addr): New function.

	* ui-out.h (ui_out_field_range_core_addr): Declaring.

	* value.h (parse_addr_range): Declaring.

	* gdb.base/watchpoint.c (buf): Changing the vector size from 10

	 procedure.
