I don't see what the point is here. As far as I know, there is no (and won't be) Windows for MIPS.

There is in that there was Windows NT MIPS and there is support already in Clang and the other components.

Thanks, I guess you learn something new every day.
Looks consistent with #121254

Yeah, NT had MIPS and Alpha at least. Amazing that anybody is interested in those old targets though, I have enough trouble with people dropping i686 support already 😉

PowerPC too.
