Move array-type va_list handling to build_va_arg
2015-05-18 Tom de Vries <tom@codesourcery.com> * gimplify.c (gimplify_modify_expr): Remove do_deref handling. (gimplify_va_arg_expr): Remove do_deref handling. Remove adding of address operator to va_list operand. * tree-stdarg.c (expand_ifn_va_arg_1): Do deref of va_list operand unconditionally. * config/i386/i386.c (ix86_gimplify_va_arg): Remove deref on va_list operand. * config/rs6000/rs6000.c (rs6000_gimplify_va_arg): Same. * config/s390/s390.c (s390_gimplify_va_arg): Same. * config/spu/spu.c (spu_gimplify_va_arg_expr): Same. * c-common.c (build_va_arg_1): New function. (build_va_arg): Add address operator to va_list operand if necessary. From-SVN: r223286
