Yes, I have. Register allocator is allocating the wrong registers for
the base registers. This probably is due to the fact that address
registers cannot be saved and restored directly, a secondary reload is
required. There is also the restriction that there is no move
operation between the address registers. For that also a secondary
reload is required. (I know its weird). I am trying to figure out why
register allocator is not assigning a base register. But even then,
reload could be asked to reload a auto-increment addresses.
