Here's how two tests mentioned here can use dg-additional-sources.  I ran
these in gcc.dg.special, which only treats files matching *[0-9].c as tests.
I don't yet know why, but 'dg-do compile' turns into 'dg-do assemble' and
vice versa when dg-additional-sources is used.
                                                                               
                                        
% cat combine-1a.c
extern int printf (const char *, ...);
                                                                               
                                        
struct x { int a; int b; };
                                                                               
                                        
bar (struct x* p)
{
    printf ("%d\n", p->a);
}
% cat combine-1.c
/* { dg-do compile } */
/* { dg-options "-combine -O3" } */
/* { dg-additional-sources combine-1a.c } */

foo (struct x* q)

    bar (q);
