RE:[sdcc-devel]getArraySizePtr(left)==INTSIZE

[Jerome B. <jer...@fr...>]

I've fixed ds390 24 bits pointer index calculation  problem. But there =
is still a former remaining bug when computing 24 bits indexed pointer  =
.

This looks like this :

result (24 bits) =3D ptr(24 bits) + (multresult =3D index * sizeof(type =
pointed))

If index and sizeof(type pointed) are both 8 bits the multresult is 16 =
bits, it's ok
but if index or sizeof(type pointed) are 16 bits multresult is still 16 =
bits, therefore the result will be that the maximum size of pointed data =
have to be less than 64k bytes.

Doesn't work for the ds390 port since we are in the lucky position that =
we
have 24bit pointers. I guess that instead of INTSIZE, ?PTRSIZE whould be =
a
better choice (that is: port->s.?ptr_size).
