Unfortunately this one introduces a regression on powerpc-linux-gnu. It was 
fixed by rth a bit later by this patch:

2002-08-01  Richard Henderson  <rth@redhat.com>

        * integrate.c (copy_rtx_and_substitute): Squash MEM_EXPR when it
        refers to a subroutine parameter.

See <http://gcc.gnu.org/ml/gcc-patches/2002-08/msg00103.html>.

I quickly checked by applying this patch and "make f771 && make check-g77" 
and the regression was fixed. I started a bootstrap on i686-linux-gnu and 
powerpc-linux-gnu with this additional patch applied.
