Go for it...

compile the following with gcc-3.0 or later, with the options

-O -mcpu=strongarm -mno-apcs-frame

void foo (char a, short b, int c);
void bar (char *a, short *b, int *c);

void foo (char a, short b, int c)
{
  bar (&a, &b, &c);
}

void bar (char *a, short *b, int *c)
{
  foo (*a, *b, *c);
}

R.
