I have a GitHub page containing my patches and a rough writeup of the issues I've encountered at https://github.com/ZirconiumX/ps2-clang-patches

There's still a lot of work to be done before I'm going to consider upstreaming the backend, if at all, but I'll do my best to get bugfixes sorted quickly.

Hi Dan,

This is pretty interesting. Do you have a project page (or something) that I can check out?

At the moment I'm really quite confused about where that PseudoCVTSL is coming from though, the pattern generating it ought to be disabled. I commented out that pattern and Clang now complains about not being able to select a valid instruction, but it doesn't segfault, suggesting that pattern is definitely causing the crash. I suppose I'll need to familiarise myself with the Clang pattern syntax anyway, because of the various major inconsistencies of the R5900 (it has no DMULT(U) or DDIV(U) instructions, which means it's not entirely MIPS III compliant). In other news, the "unexpected illegal type" assert is now fixed in trunk, which is the first step in a long, long path to bringing up support for this...quirky...architecture.
