* config/alpha/alpha.c (function_arg): Don't pass small aggregates
in floating point registers. Validate that we don't receive complex
values here. Use #elif.
(return_in_memory, function_value): New.
(alpha_va_arg): Handle complex values as two arguments.
* config/alpha/alpha.h (RETURN_IN_MEMORY): Use return_in_memory.
(FUNCTION_VALUE, LIBCALL_VALUE): Use function_value.
(SPLIT_COMPLEX_ARGS): New.
* config/alpha/alpha-protos.h: Update.
