Andreas, could you adopt the patch of comment #4 and see if it still fixes this
bug?

This should not have been in waiting as it was waiting on a developer response
and not the reporter.

Andreas,
Thanks for spotting the typo. I also updated the patch to ensure that
we are giving an address register indirect to clr.

The comment in the patch has a typo: clr.b (%a0) should be clr.b (%a1).

FWIW, the mainline gcc with -O2 -fomit-frame-pointer produces
f:
move.l 4(%sp),%a0
move.l (%a0),%a1
move.l 4(%a0),%a0
clr.b (%a0,%a1.l)

With this patch, I get:

move.l (%a0),%a1
add.l 4(%a0),%a1

Test case (see also
http://gcc.gnu.org/ml/gcc-patches/2004-11/msg01109.html):
struct X {
char *a;
/* other members */
int b;
};
void f (struct X *x)
{
x-a[x-b] = 0;
}
