Hi. This patch removes obsolete REGISTER_MOVE_COST and MEMORY_MOVE_COST macros from the STORMY16 back end in the GCC and introduces equivalent TARGET_MEMORY_MOVE_COST target hook. Default version of the TARGET_REGISTER_MOVE_COST target hook is used. Regression tested on xstormy16-unknown-elf. OK to install? * config/stormy16/stormy16.h (REGISTER_MOVE_COST, MEMORY_MOVE_COST): Remove. * config/stormy16/stormy16.c: Include reload.h. (xstormy16_memory_move_cost): New function. (TARGET_MEMORY_MOVE_COST): Define. Anatoly.
