Subject: sh.c (sh_gimplify_va_arg_expr): Don't call pass_by_reference.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=03603192000fe203738a8aa1708ebc566cd2a0fa;p=gcc.git

sh.c (sh_gimplify_va_arg_expr): Don't call pass_by_reference.

	* sh.c (sh_gimplify_va_arg_expr): Don't call pass_by_reference.
	(sh_pass_by_reference): Work around std_gimplify_va_arg_expr bug.
	* t-sh (MULTILIB_CPUS): s/ML_m/ML_sh/g .
	* t-sh64 (MULTILIB_CPU_DIRS): Likewise.  Match trailing slashes
	in substitutions.
	(MULTILIB_DIRNAMES): Remove defunct removal of /media32.
