Subject: Fix builtin decls generated in tree.c
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5707996c14fcbbe9e71f97e703f0f5767b1f0611;p=gcc.git

Fix builtin decls generated in tree.c

	* tree.c (set_call_expr_flags): Fix string for ECF_RET1.
	(build_common_builtin_nodes): Do not set ECF_RET1 for memcpy, memmove,
	and memset. They are handled by builtin_fnspec.
