By the way, the unmatched portability of Plan 9 and Go stems from the way Ken structured that compiler. My talk at GopherCon about the Go assembler describes this architecture and why it worked so well. Others feel that by being unorthodox it is clearly bogus and we are jackasses, but such complainers only notice the difference and don't ask why the difference is there.

Yes. Ken wrote the first version for the National 32000 (maybe even 16000?) on the Sequent. He ported to the MIPS when we started Plan 9.

What is the history of Plan9's C compiler? Was it a from scratch implementation?

Chris Fraser and Dave Hanson did LLC and wrote a book about it, very clean and pedagogically valuable.
