Hello. This patch removes obsolete FUNCTION_VALUE, LIBCALL_VALUE and FUNCTION_VALUE_REGNO_P macros from M32R back end in the GCC and introduces equivalent TARGET_FUNCTION_VALUE, TARGET_LIBCALL_VALUE and TARGET_FUNCTION_VALUE_REGNO_P target hooks. Regression tested on m32r-unknown-elf. OK to install? * config/m32r/m32r.c (m32r_function_value, m32r_libcall_value, m32r_function_value_regno_p): New functions. (TARGET_FUNCTION_VALUE, TARGET_LIBCALL_VALUE, TARGET_FUNCTION_VALUE_REGNO_P): Declare. * config/m32r/m32r.h: (FUNCTION_VALUE, LIBCALL_VALUE, FUNCTION_VALUE_REGNO_P): Remove. Anatoly.
