 Contributors to GCC
 *******************
 
    In addition to Richard Stallman, several people have written parts
 of GCC.
 
    * 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 front end for C++, as
      well as 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.
 
    * Gerald Baumgartner added the signature extension to the C++
      front-end.
 
    * 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 GCC to VMS.
 
    * Alex Crain provided changes for the 3b1.
 
    * Greg Satz and Chris Hanson assisted in making GCC 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 GCC to the Mips cpu.
 
    * Devon Bowen, Dale Wiles and Kevin Zachmann ported GCC to the Tahoe.
 
    * Jonathan Stone wrote the machine description for the Pyramid
      computer.
 
    * Gary Miller ported GCC 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).
 
    * NeXT, Inc. donated the front end that supports the Objective C
      language.
 
    * 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.  Later at Cygnus Support,
      he worked on the rs6000 and PowerPC ports.
 
    * 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).
 
    * Holger Teutsch provided the support for the Clipper cpu.
 
    * Kresten Krab Thorup wrote the run time support for the Objective C
      language.
 
    * Stephen Moshier contributed the floating point emulator that
      assists in cross-compilation and permits support for floating
      point numbers wider than 64 bits.
 
    * David Edelsohn contributed the changes to RS/6000 port to make it
      support the PowerPC and POWER2 architectures.
 
    * Steve Chamberlain wrote the support for the Hitachi SH processor.
 
    * Peter Schauer wrote the code to allow debugging to work on the
      Alpha.
 
    * Oliver M. Kellogg of Deutsche Aerospace contributed the port to the
      MIL-STD-1750A.
 
    * Michael K. Gschwind contributed the port to the PDP-11.
 
    * David Reese of Sun Microsystems contributed to the Solaris on
      PowerPC port.
