Browse Source 
debug_registers_used, CONTEXT_EXTENDED_REGISTERS,
	CONTEXT_FLOATING_POINT, CONTEXT_DEBUG_REGISTERS,
	CONTEXT_DEBUGGER, CONTEXT_DEBUGGER_DR): Delete.
	(thread_rec): Get context using the low target.
	(child_add_thread): Call thread_added on the low target,
	which does the same thing.
	(regptr): Delete.
	(do_initial_child_stuff): Remove debug registers references.
	Set context using the low target.  Resume threads after
	setting the contexts.
	(child_continue): Remove dead variable.  Remove debug
	registers references.
	(child_fetch_inferior_registers): Go through the low target.
	(do_child_store_inferior_registers): Remove.
	(child_store_inferior_registers): Go through the low target.
	(win32_resume): Remove debug registers references.
	Set context using the low target.
	(handle_exception): Change return type to void.  Don't record
	context here.  Set status to TARGET_WAITKIND_SPURIOUS on a
	first chance exception.
	(get_child_debug_event): Change return type to void.  Remove
	goto loop.  Always return after waiting for debug event.
	(win32_wait): Convert to switch statement.  Handle spurious
	events.

	* win32-i386-low.c (debug_registers_changed,
	debug_registers_used): New.
	(initial_stuff): Rename to ...
	(i386_initial_stuff): ... this.  Clear debug registers
	state variables.
	(store_debug_registers): Delete.
	(i386_get_thread_context): New.
	(load_debug_registers): Delete.
	(i386_set_thread_context): New.
	(i386_thread_added): New.
	(single_step): Rename to ...
	(i386_single_step): ... this.
	(do_fetch_inferior_registers): Rename to ...
	(i386_fetch_inferior_register): ... this.
	(i386_store_inferior_register): New.
	(the_low_target): Adapt to new interface.

	* win32-arm-low.c (CONTEXT_FLOATING_POINT): Define.
	(arm_get_thread_context): New.
	(arm_set_thread_context): New.
	(regptr): New.
	(do_fetch_inferior_registers): Rename to ...
	(arm_fetch_inferior_register): ... this.
	(arm_store_inferior_register): New.
	(arm_wince_breakpoint): Reimplement as unsigned long.
	(arm_wince_breakpoint_len): Define.
	(the_low_target): Adapt to new interface.

	* win32-low.h (target_ops): Remove regmap, store_debug_registers and
	load_debug_registers.  Add get_thread_context, set_thread_context,
	thread_added and store_inferior_register.  Rename
	fetch_inferior_registers to fetch_inferior_register.
	(regptr): Remove declaration.
