* doc/tm.texi (TARGET_STRUCT_VALUE_RTX): Document
new value 2 for incoming.
* function.c (expand_function_start): Call struct_value_rtx
with incoming as 2.
* config/sparc/sparc.md: Comment updated_return.
* config/sparc/sparc.opt: Add -mstd-struct-return option.
* config/sparc/sparc.c (sparc_struct_value_rtx): Use standard
struct return if sparc_std_struct_return and incoming is 2.
(print_operand): Do not adjust return if
sparc_std_struct_return.
