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 loop optimizations.

• Nobuyuki Hikichi of Software Research Associates, Tokyo, contributed the support for the Sony NEWS machine.

• Charles LaBrec contributed the support for the Integrated Solutions 68020 system.

• 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.

• Christopher Smith did the port for Convex machines.

• 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.

• Alain Lichnewsky ported GNU CC to the Mips cpu.

• Devon Bowen, Dale Wiles and Kevin Zachmann ported GNU CC to the Tahoe.

• Jonathan Stone wrote the machine description for the Pyramid computer.

• Gary Miller ported GNU CC to Charles River Data Systems machines.

• 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 Motorola 88000.

• 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 protoize and unprotoize 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 register allocation.

• 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).
