I haven't looked at this code in detail, but since amd64 passes the first
6? int/long/ptr in the same registers and uses the same convention
for varargs you probably get away with it.
OTOH, for example, the starcore DSP uses different registers for
int and ptr (for the first 2 args) but stacks everything for
varargs.
