/* Handling of 8-bit SP versus 16-bit SP is as follows:
-msp8 is used internally to select the right multilib for targets with
8-bit SP. -msp8 is set automatically by DRIVER_SELF_SPECS for devices
with 8-bit SP or by multilib generation machinery. If a frame pointer is
needed and SP is only 8 bits wide, SP is zero-extended to get FP.
TARGET_TINY_STACK is triggered by -mtiny-stack which is a user option.
This option has no effect on multilib selection. It serves to save some
bytes on 16-bit SP devices by only changing SP_L and leaving SP_H alone.
These two properties are reflected by built-in macros __AVR_SP8__ resp.
__AVR_HAVE_8BIT_SP__ and __AVR_HAVE_16BIT_SP__. During multilib generation
there is always __AVR_SP8__ == __AVR_HAVE_8BIT_SP__. */

When accessing RAM, use X as imposed by the hardware, i.e. just use pre-decrement, post-increment and indirect addressing with the X register.
