It is what cfgexpand.c outputs.  We can revert this part of the patch, 
or add a *.rtl dump different from *.expand but it is apparently what 
Honza wanted to have in the output.

It does at least for the attached file.

;; Function d (d)

Partition 0: size 4 align 4
     x, offset 0
;; basic block 0, loop depth 0, count 0

etc.

extern int x;

static void a(void)
{
  x++;
}

__attribute__ ((noinline)) static void c(int b, int *a)
{
  x += b + *a;
}

int d(int y)
{
  int x;
  a();
  c(42, &x);
  return x;
}
