Hello all,
The target that i am working on is 16bit, big endian and with 16 registers.
It has this particular addressing mode
load Rd, Ra[offset]
store Rs, Ra[offset]
where the offset should be positive, base register Ra should be an
even register and for the source or the destination register

GCC doesn't provide any easy way for the source address to depend on the
destination address, or vice versa.

Hello all,
For a port that i am working on has this particular addressing mode
load Rd, Ra[offset]

For the above two instructions base register Ra should be an even
register. This i have implemented using the macros REGNO_OK_FOR_BASE_P
and BASE_REG_CLASS by creating a class
