Minor nit, should be formatted as:

Sorry for missing this. Alex, it should be fixed anyway.
I don't think we should we restrict this to (plus (mult X Y) Z),
since addresses can be more complicated than that. One way to
search for all MULTs is:
subrtx_iterator::array_type array;
FOR_EACH_SUBRTX (iter, array, x, NONCONST)
{
rtx x = *iter;
if (GET_CODE (x) == MULT && CONST_INT_P (XEXP (x, 1)))
...
}
(Needs rtl-iter.h)
I am agree it would be nice to process a general case. Alex, you can do
this as a separate patch if you want.
Richard, thank you for looking at this patch too.
