commit r152019 broke architectures with more than 255 registers

Our architecture(TCE) can have LOTS of registers.

It seems r152019 changed some register bookkeeping data structures to 8-bit. This broke support for architectures with >255 registers.

Please revert this change or make those register-related values at least 16 bits wide.

Ughh... yeah I would have to agree here. The AMDIL backend uses more than 256 registers to model its register file correctly.

I agree. We can limit the number of physregs to 64k, but no more.

This has been changed to uint16_t in r152100.

I have reverted the commits that limited the concatenated register and instruction names to 64k. They would have caused problems for a 16k register target.

Heikki, please let me know if you are having problems with the limits enforced by TableGen now.
