* sparc-tdep.c (SPARC_HAS_FPU): Define.
(sparc_extract_return_value): New function, required to handle machines without floating point. (sparc_store_return_value): Ditto. * config/sparc/tm-sparc.h (EXTRACT_RETURN_VALUE): Call sparc_extract_return_value instead of using inline code. (sparc_extract_return_value): Declare. (STORE_RETURN_VALUE): Call sparc_store_return_value instead of using inline code. (sparc_store_return_value): Declare.
