GNU Pascal is based on GNU CC by Richard Stallman. Several
people have contributed to GNU CC:
- The idea of using RTL and some of the optimization ideas came from
the program PO written at the University of Arizona by Jack Davidson
and Christopher Fraser. See “Register Allocation and Exhaustive
Peephole Optimization”, Software Practice and Experience 14 (9),
Sept. 1984, 857-866.
- Paul Rubin wrote most of the preprocessor.
- Leonard Tower wrote parts of the parser, RTL generator, and RTL
definitions, and of the Vax machine description.
- Ted Lemon wrote parts of the RTL reader and printer.
- Jim Wilson implemented loop strength reduction and some other
- Nobuyuki Hikichi of Software Research Associates, Tokyo, contributed
the support for the Sony NEWS machine.
- Charles LaBrec contributed the support for the Integrated Solutions
- Michael Tiemann of Cygnus Support wrote the support for inline
functions and instruction scheduling. Also the descriptions of the
National Semiconductor 32000 series cpu, the SPARC cpu and part of
the Motorola 88000 cpu.
- Jan Stein of the Chalmers Computer Society provided support for
Genix, as well as part of the 32000 machine description.
- Randy Smith finished the Sun FPA support.
- Robert Brown implemented the support for Encore 32000 systems.
- David Kashtan of SRI adapted GNU CC to VMS.
- Alex Crain provided changes for the 3b1.
- Greg Satz and Chris Hanson assisted in making GNU CC work on HP-UX
for the 9000 series 300.
- William Schelter did most of the work on the Intel 80386 support.

- Paul Petersen wrote the machine description for the Alliant FX/8.
- Dario Dariol contributed the four varieties of sample programs that
print a copy of their source.

- Richard Kenner of the New York University Ultracomputer Research
Laboratory wrote the machine descriptions for the AMD 29000, the DEC
Alpha, the IBM RT PC, and the IBM RS/6000 as well as the support for
instruction attributes. He also made changes to better support RISC
processors including changes to common subexpression elimination,
strength reduction, function calling sequence handling, and
condition code support, in addition to generalizing the code for
frame pointer elimination.
- Richard Kenner and Michael Tiemann jointly developed reorg.c, the
delay slot scheduler.
- Mike Meissner and Tom Wood of Data General finished the port to the
- Masanobu Yuhara of Fujitsu Laboratories implemented the machine
description for the Tron architecture (specifically, the Gmicro).
- James van Artsdalen wrote the code that makes efficient use of the
Intel 80387 register stack.
- Mike Meissner at the Open Software Foundation finished the port to
the MIPS cpu, including adding ECOFF debug support, and worked on
the Intel port for the Intel 80386 cpu.
- Ron Guilmette implemented the
tools, the support for Dwarf symbolic debugging information, and
much of the support for System V Release 4. He has also worked
heavily on the Intel 386 and 860 support.
- Torbjorn Granlund implemented multiply- and divide-by-constant
optimization, improved long long support, and improved leaf function
- Mike Stump implemented the support for Elxsi 64 bit CPU.
- John Wehle added the machine description for the Western Electric
32000 processor used in several 3b series machines (no relation to
the National Semiconductor 32000 processor).
