[llvm-dev] 16-bit bytes support

[Ivan Krasin via llvm-dev]

Hi Mikaël!

16-bit byte was a major pain back in the day, and we never fixed all known
failures. In part, it's because C standard really wants 8-bit chars.

Btw, why is DCPU16 still a thing? :)

Hi.

I'm working on a backend for the [DCPU16](https://github.com/te
chcompliant/TC-Specs/blob/master/CPU/DCPU.md), a fictional CPU. The main
subtlety is that the bytes are 16 bits instead of 8. There is already a
[working backend](https://github.com/krasin/llvm-dcpu16), but it does a lot
of source modification to support 16 bit words. I try to update it to
latest llvm, but it obviously fails since the new code assumes 1 word == 8
bits. Any idea of a robust way to do such backend?

Have a good day,
Mikaël
