About 3 1/2 years ago I was working with such a system at GE in Philadelphia.
The compiler was actually a 2 parter, a parser/lexer that produced a parse
tree in a LISPish notation, and then a translator that turned the LISPish
code into VAX Macro Assembly language.  Both of these parts were written
at Carnegie-Mellon, I believe.  I don't recall what GE did to get them.
Anyway, I think part or all of these sections were written in VAX PASCAL
(this is VAX/VMS, buy the way, unfortunately).  Along with the VAX Macro
code, there were quite a few run-time modules to link in, which constituted
the main simulator.  These were all written in BLISS, and I believe that
they came from CMU as well.  Finally, we had a local front-end to the
simulator, which started out in Fortran.  I rewrote this in Pascal, as
the VAX/VMS Fortran compiler is kind of brain-damaged in its allocation of
machine registers, and our local code ended up tromping over a few vital
BLISS variables until it was rewritten in Pascal.  Anyway, it sounds like
the best thing you could do would be to contact the CMU Computer Science
department (who might even be around here on the net; imagine that).  I
wouldn't imagine much success getting through to anyone at GE.
