   > As for write_register_bytes() can it be avoided?  I've just posted ``regcache_cooked_write_with_offset_hack().  But I don't think that hack is right here.  Perhaphs a single register read - modify - write function is needed?

   Hmm,

   I just hit a need for the same operation while implementing some pseudo 
   registers.  Just adding:

   regcache_raw_read_part(regcache,regnum,offset,length,buf)
   regcache_raw_write_part(regcache,regnum,offset,length,buf)

Where OFFSET would be the byte offset into the register I suppose.

Seems like a good idea to me.
