* 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.
