Given that the maintainer previously said they had tried to pay to get GCC and LLVM ported multiple times, all of which failed, money doesn’t seem to have helped.

Surely the question is how much they tried to pay? Clearly the answer is "not enough".

I mean at one point I had LLVM targeting Xbox 360, PS3, and Wii so I'm sure it's possible, it just needs some imagination and elbow grease :)
