Agree. The target description part is rewritten in the new patch, and
it should be clean now. The original xml description is split into
three xml files, and these features are documented in gdb.texinfo.
- tic6x-core.xml: core registers, exist on all C6x variants.
- tic6x-gp.xml: general purpose reigster A16-A31, B16-B31.
- tic6x-c6xp.xml: some control registers.
These three xml files compose another three xml files,
tic6x-{c64xp,c64x,c62x}-linux.xml.
gdbserver part is slightly changed for calling
init_registers_tic6x_{c63x,c64x,c64xp}_linux in tic6x_arch_setup,
according to computed CPU ID.
