Contributors to GDB

Richard Stallman was the original author of GDB, and of many other GNU
programs.  Many others have contributed to its development.  This
section attempts to credit major contributors.  One of the virtues of
free software is that everyone is free to contribute to it; with
regret, we cannot actually acknowledge everyone here.  The file
`ChangeLog' in the GDB distribution approximates a blow-by-blow account.
   Changes much prior to version 2.0 are lost in the mists of time.
     _Plea:_ Additions to this section are particularly welcome.  If you
     or your friends (or enemies, to be evenhanded) have been unfairly
     omitted from this list, we would like to add your names!
   So that they may not regard their many labors as thankless, we
particularly thank those who shepherded GDB through major releases:
Andrew Cagney (releases 6.1, 6.0, 5.3, 5.2, 5.1 and 5.0); Jim Blandy
(release 4.18); Jason Molenda (release 4.17); Stan Shebs (release 4.14);
Fred Fish (releases 4.16, 4.15, 4.13, 4.12, 4.11, 4.10, and 4.9); Stu
Grossman and John Gilmore (releases 4.8, 4.7, 4.6, 4.5, and 4.4); John
Gilmore (releases 4.3, 4.2, 4.1, 4.0, and 3.9); Jim Kingdon (releases
3.5, 3.4, and 3.3); and Randy Smith (releases 3.2, 3.1, and 3.0).
   Richard Stallman, assisted at various times by Peter TerMaat, Chris
Hanson, and Richard Mlynarik, handled releases through 2.8.
   Michael Tiemann is the author of most of the GNU C++ support in GDB,
with significant additional contributions from Per Bothner and Daniel
Berlin.  James Clark wrote the GNU C++ demangler.  Early work on C++
was by Peter TerMaat (who also did much general update work leading to
release 3.0).
   GDB uses the BFD subroutine library to examine multiple object-file
formats; BFD was a joint project of David V.  Henkel-Wallace, Rich
Pixley, Steve Chamberlain, and John Gilmore.
   David Johnson wrote the original COFF support; Pace Willison did the
original support for encapsulated COFF.
   Brent Benson of Harris Computer Systems contributed DWARF 2 support.
   Adam de Boor and Bradley Davis contributed the ISI Optimum V support.
Per Bothner, Noboyuki Hikichi, and Alessandro Forin contributed MIPS
support.  Jean-Daniel Fekete contributed Sun 386i support.  Chris
Hanson improved the HP9000 support.  Noboyuki Hikichi and Tomoyuki
Hasei contributed Sony/News OS 3 support.  David Johnson contributed
Encore Umax support.  Jyrki Kuoppala contributed Altos 3068 support.
Jeff Law contributed HP PA and SOM support.  Keith Packard contributed
NS32K support.  Doug Rabson contributed Acorn Risc Machine support.
Bob Rusk contributed Harris Nighthawk CX-UX support.  Chris Smith
contributed Convex support (and Fortran debugging).  Jonathan Stone
contributed Pyramid support.  Michael Tiemann contributed SPARC support.
Tim Tucker contributed support for the Gould NP1 and Gould Powernode.
Pace Willison contributed Intel 386 support.  Jay Vosburgh contributed
Symmetry support.  Marko Mlinar contributed OpenRISC 1000 support.
   Andreas Schwab contributed M68K GNU/Linux support.
   Rich Schaefer and Peter Schauer helped with support of SunOS shared
libraries.
   Jay Fenlason and Roland McGrath ensured that GDB and GAS agree about
several machine instruction sets.
   Patrick Duval, Ted Goldstein, Vikram Koka and Glenn Engel helped
develop remote debugging.  Intel Corporation, Wind River Systems, AMD,
and ARM contributed remote debugging modules for the i960, VxWorks,
A29K UDI, and RDI targets, respectively.
   Brian Fox is the author of the readline libraries providing
command-line editing and command history.
   Andrew Beers of SUNY Buffalo wrote the language-switching code, the
Modula-2 support, and contributed the Languages chapter of this manual.
   Fred Fish wrote most of the support for Unix System Vr4.  He also
enhanced the command-completion support to cover C++ overloaded symbols.
   Hitachi America (now Renesas America), Ltd. sponsored the support for
H8/300, H8/500, and Super-H processors.
   NEC sponsored the support for the v850, Vr4xxx, and Vr5xxx
processors.
   Mitsubishi (now Renesas) sponsored the support for D10V, D30V, and
M32R/D processors.
   Toshiba sponsored the support for the TX39 Mips processor.
   Matsushita sponsored the support for the MN10200 and MN10300
processors.
   Fujitsu sponsored the support for SPARClite and FR30 processors.
   Kung Hsu, Jeff Law, and Rick Sladkey added support for hardware
watchpoints.
   Michael Snyder added support for tracepoints.
   Stu Grossman wrote gdbserver.
   Jim Kingdon, Peter Schauer, Ian Taylor, and Stu Grossman made nearly
innumerable bug fixes and cleanups throughout GDB.
   The following people at the Hewlett-Packard Company contributed
support for the PA-RISC 2.0 architecture, HP-UX 10.20, 10.30, and 11.0
(narrow mode), HP's implementation of kernel threads, HP's aC++
compiler, and the Text User Interface (nee Terminal User Interface):
Ben Krepp, Richard Title, John Bishop, Susan Macchia, Kathy Mann,
Satish Pai, India Paul, Steve Rehrauer, and Elena Zannoni.  Kim Haase
provided HP-specific information in this manual.
   DJ Delorie ported GDB to MS-DOS, for the DJGPP project.  Robert
Hoehne made significant contributions to the DJGPP port.
   Cygnus Solutions has sponsored GDB maintenance and much of its
development since 1991.  Cygnus engineers who have worked on GDB
fulltime include Mark Alexander, Jim Blandy, Per Bothner, Kevin
Buettner, Edith Epstein, Chris Faylor, Fred Fish, Martin Hunt, Jim
Ingham, John Gilmore, Stu Grossman, Kung Hsu, Jim Kingdon, John Metzler,
