cp-gimplify.c (cp_gimplify_expr): Use get_initialized_tmp_var.
* cp-gimplify.c (cp_gimplify_expr): Use get_initialized_tmp_var. The comment for get_formal_tmp_var says that it shouldn't be used for expressions whose value might change between initialization and use, and in this case we're creating a temporary precisely because the value might change, so we should use get_initialized_tmp_var instead. I also noticed that many callers of get_initialized_tmp_var pass NULL for post_p, so it seems appropriate to make it a default argument. gcc/ * gimplify.h (get_initialized_tmp_var): Add default argument to post_p. * gimplify.c (gimplify_self_mod_expr, gimplify_omp_atomic): Remove NULL post_p argument. * targhooks (std_gimplify_va_arg_expr): Likewise.
