[TUHS] IBM RT/PC compilers [was Re: Any Bell 8-bit UNIX Efforts?

[George Michaelson]

I used BSD/RT and I don't recall anything that good and my C is pretty
terrible: if there were biblical error codes I would have expected to
tickle them.

AIX 2 releases bundled pcc with the HCR optimization phase added. I’m not sure about AIX 3 and beyond, since I left before they were released. The “strategic” plan was a reimplementation of the PL.8 compiler as a C compiler with the work done by an IBM group in Toronto. I suspect that was extra cost option and that pcc with HCR was still bundled in the base. I have the impression that AOS (BSD for RT) eventually also included the HCR phase.
