Make canonical_va_list_type more strict
2016-09-10 Tom de Vries <tom@codesourcery.com>
PR C/71602
* builtins.c (std_canonical_va_list_type): Strictly return non-null for
va_list type only.
* config/i386/i386.c (ix86_canonical_va_list_type): Same.
* gimplify.c (gimplify_va_arg_expr): Handle &va_list.
* c-common.c (build_va_arg): Handle more strict
targetm.canonical_va_list_type. Replace first argument type error with
assert.
* c-c++-common/va-arg-va-list-type.c: New test.
