Hello. This patch removes obsolete GO_IF_MODE_DEPENDENT_ADDRESS macros from STORMY16 back end in the GCC and introduces equivalent TARGET_MODE_DEPENDENT_ADDRESS_P target hook. Regression tested on xstormy16-unknown-elf. OK to install? * config/stormy16/stormy16.h (GO_IF_MODE_DEPENDENT_ADDRESS): Remove. * config/stormy16/stormy16-protos.h (xstormy16_mode_dependent_address_p): Remove. * config/stormy16/stormy16.c (xstormy16_mode_dependent_address_p): Make static. Change return type to bool. Change argument type to const_rtx. Remove dead code. (TARGET_MODE_DEPENDENT_ADDRESS_P): Define. Anatoly.
