[gnu.gcc] Retargetting GNU CC to a non byte-addressable machine

dan%jeremy.DEC@DECWRL.DEC.COM (Dan Frommer) (04/23/89)

I'm currently in a beginning of a process to retarget GCC to a 16 bit machine
which has only word addressability (i.e. - its bytes are actually 16 bit wide). 

This is a proprietary processor for which code will be crossed-compiled under
VAX/VMS. 

It seems that the 16-bit issue can be solved quite easily unlike the
addressability one. An attempt to modify BITS_PER_UNIT to 16 does not seem to
be sufficient. 

Is this retarget feasible? Has anyone ever attempted such a retarget?

Any response will be appreciated,
