(A0)+ not always used as expected

[GunnarVB]

Hello Stefan,

I did some tests of your new GCC impovements I saw following:

void memclr (int length, int * ptr)
{
 for(;length--;){
   *ptr++= 0;
   *ptr++= 0; 
 }
}

==>

_memclr:
        jra .L2
.L3:
        clr.q (a0)+
.L2:
        dbral d0,.L3
        rts

-- This is excellent!! Great result! Thank you!

But I also found this:

void memclr (int length, int * ptr)
{
 for(;length--;){
   *ptr++= 0;
   *ptr++= 0;
   *ptr++= 0;
   *ptr++= 0;   
 }
}

==>

_memclr:
        jra .L2
.L3:
        clr.l (a0)+
        clr.q (a0)
        lea (12,a0),a0
        clr.l (-4,a0)
.L2:
        dbral d0,.L3
        rts

What happened here? I would have likes to see this here:

        clr.q (a0)+
        clr.q (a0)+

Can you fix this? Please
