X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=6268b92246a83813217648665eaf168eb02e19ba;p=gcc.git

calls.c (emit_library_call_value): Don't use a fixed argument after VA_CLOSE, i.e.

	* calls.c (emit_library_call_value): Don't use a fixed
	argument after VA_CLOSE, i.e. out of scope in traditional C.

	* emit-rtl.c (gen_rtvec): Likewise.
