Subject: rx.c (rx_function_value): Do not promote vector types.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=e50869f7a638328f609afc0cbfa77ccaa2cbe01a;p=gcc.git

rx.c (rx_function_value): Do not promote vector types.

	* config/rx/rx.c (rx_function_value): Do not promote vector types.
	(rx_promote_function_mode): Likewise.
	* config/rx/rx.h (LIBCALL_VALUE): Likewise.
