Browse source 
(sparc64_store_floating_fields, sparc64_store_floating_fields):
Use check_typedef to get subtypes of structures and unions.
(sparc64_store_return_value): Fix calculation of the appropriate
offset into VALBUF when storing a structure or union.
(sparc64_return_value): New function.
(sparc64_use_struct_convention): Remove function.
(sparc64_init_abi): Set return_value, don't set
extract_return_value, store_return_value and
use_struct_convention.
