Optimizing XPL Compiler - XPL source version
The source code for the Optimizing XPL compiler
is based on the McKeeman, Horning, and Wortman XPL compiler. The alterations
were written by Robin Vowels. This compiler generates code for the IBM System
/370 and its successors.
A second version of the Optimising XPL Compiler
has been adapted for the IBM System 390 (also the PC, see below). It is
written in IBM VisualAge PL/I, and compiles and runs
under PL/I without the aid of the XPL submonitor XMON, and produces
IBM System 390 object code. (However, when an XPL source program
has been compiled with that compiler, that object program must run under XMON.)
This version will also run on the IBM PC. A monitor has been written
for the PC,
along with an interpreter for the IBM System 360. For details, write me,
as I do not have any more space on the web site to store it.
Warning: the object code produced by this second version of the
compiler has not been tested on an
IBM System 390. Anyone who has one is invited to test run.
XPL Compiler Generator System for Intel 486.
A version of the XPL compiler generator system is available for the Intel
486. Details below:

XPL compiler ported to Intel (on FreeBSD)

I've dug out a rather old compiler/compiler generator called XPL, and
ported it to the Intel 486. It's documented in the book "A Compiler
Generator" by McKeeman, Horning and Wortman, published by Prentice-Hall,
1970, ISBN 13-155077-2. The original compiler was designed for the IBM
S/360. The language is XPL, a dialect of PL/I. The compiler is written
in XPL. The package constain the compiler, bnf grammar, grammar
analyzer,
skeleton compiler, S/360 emulator to bootstrap the build, and all
source.
It was ported on a FreeBSD Unix system, so I suspect that other BSD
variants will require a few changes, and Linux a few more.
It's available from:
XPL for Intel 486.
