It's a bit rough around
the edges and the runtime code needs some work (division and
remainder are missing), but it does compile B code correctly,
generating acceptable code (for my taste, though the function call
sequence could be better).
A suggestion, Load TSS/8 on to your simh system with its Algol compiler
and look at how it generated code. I would suspect you can use Algol's
calling conventions and probably some of its runtime. Google is your
friend. I had it running a while back, but do not have it active at the
moment - the key is all the pieces should be findable in the wild,.
I hope some of you enjoy this compiler for an important historical
language for an important historical computer (makes me wonder why
the two weren't married before).
Might have been, although when Ken created B for the PDP-7, BCPL was his
model and there were already implementations of BCPL around for a number of
processors. I would not be surprised if there was a BCPL/8. I would check
in the DECUS library, much of which I think can be found online these days
