I was going to mention it, but you guys know very well the drill, so
unless this hardware changes fundamental parts of the middle end in
ways that are unnatural to most other targets (doesn't seem that way),
then I see no reason why not have it upstream.
However, there are no tests at all on the reviews, and that is a red
flag. I was expecting Clang driver tests, code-gen tests, instruction
encoding/decoding, ABI and frame lowering tests, etc. Without these, I
can't see the benefits of having the target upstream, since I'll have
no idea what your target is expected to do when I add/change some
generic code generation option.
