Subject: m32c.c (cris_memory_move_cost): New.
X-Git-Tag: releases/gcc-4.6.0~4013
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b95491a041e1c7da0aaab650e4f3cad2c341baae;p=thirdparty%2Fgcc.git

m32c.c (cris_memory_move_cost): New.

	* config/cris/m32c.c (cris_memory_move_cost): New.
	(cris_register_move_cost): Make static. Change arguments type from
	enum reg_class to reg_class_t.
	(TARGET_REGISTER_MOVE_COST, TARGET_MEMORY_MOVE_COST): Define.
	* config/cris/cris.h (REGISTER_MOVE_COST, MEMORY_MOVE_COST): Remove.
	* config/cris/cris-protos.h (cris_register_move_cost): Remove.
