 Dean Elsner wrote the original gas for vax.  [more details?]

 Jay Fenlason maintained gas for a while, adding support for
 gdb-specific debug information and the 68k series machines, most of
 the preprocessing pass, and extensive changes in messages.c,
 input-file.c, write.c.

 K. Richard Pixley maintained gas for a while, adding various
 enhancements and many bug fixes, including merging support for several
 processors, breaking gas up to handle multiple object file format
 backends (including heavy rewrite, testing, an integration of the coff
 and b.out backends), adding configuration including heavy testing and
 verification of cross assemblers and file splits and renaming,
 converted gas to strictly ansi C including full prototypes, added
 support for m680[34]0 & cpu32, considerable work on i960 including a
 coff port (including considerable amounts of reverse engineering), a
 sparc opcode file rewrite, decstation, rs6000, and hp300hpux host
 ports, updated "know" assertions and made them work, much other
 reorganization, cleanup, and lint.

 Ken Raeburn wrote the high-level BFD interface code to replace most of
 the code in format-specific I/O modules.

 The original Vax-VMS support was contributed by David L. Kashtan.
 Eric Youngdale and Pat Rankin have done much work with it since.

 The Intel 80386 machine description was written by Eliot Dresselhaus.

 Minh Tran-Le at IntelliCorp contributed some AIX 386 support.

 The Motorola 88k machine description was contributed by Devon Bowen of
 Buffalo University and Torbjorn Granlund of the Swedish Institute of
 Computer Science.

 Keith Knowles at the Open Software Foundation wrote the original MIPS
 back end (tc-mips.c, tc-mips.h), and contributed Rose format support
 that hasn't been merged in yet.  Ralph Campbell worked with the MIPS
 code to support a.out format.

 Support for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors
 (tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format
 (obj-ieee), was written by Steve Chamberlain of Cygnus Solutions.
 Steve also modified the COFF back end (obj-coffbfd) to use BFD for
 some low-level operations, for use with the Hitachi, 29k and Zilog
 targets.

 John Gilmore built the AMD 29000 support, added .include support, and
 simplified the configuration of which versions accept which
 pseudo-ops.  He updated the 68k machine description so that Motorola's
 opcodes always produced fixed-size instructions (e.g. jsr), while
 synthetic instructions remained shrinkable (jbsr).  John fixed many
 bugs, including true tested cross-compilation support, and one bug in
 relaxation that took a week and required the proverbial one-bit fix.

 Ian Lance Taylor of Cygnus Solutions merged the Motorola and MIT
 syntaxes for the 68k, completed support for some COFF targets (68k,
 i386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael
 Meissner's mips-tfile program, wrote the PowerPC and RS/6000 support,
 and made a few other minor patches.  He handled the binutils releases
 for versions 2.7 through 2.9.

 David Edelsohn contributed fixes for the PowerPC and AIX support.

 Steve Chamberlain made gas able to generate listings.

 Support for the HP9000/300 was contributed by Glenn Engel of HP.

 Support for ELF format files has been worked on by Mark Eichin of
 Cygnus Solutions (original, incomplete implementation), Pete
 Hoogenboom at the University of Utah (HPPA mainly), Michael Meissner
 of the Open Software Foundation (i386 mainly), and Ken Raeburn of
 Cygnus Solutions (sparc, initial 64-bit support).

 Several engineers at Cygnus Solutions have also provided many small
 bug fixes and configuration enhancements.

 The initial Alpha support was contributed by Carnegie-Mellon
 University.  Additional work was done by Ken Raeburn of Cygnus
 Solutions.  Richard Henderson then rewrote much of the Alpha support.

 Ian Dall updated the support code for the National Semiconductor 32000
 series, and added support for Mach 3 and NetBSD running on the PC532.

 Klaus Kaempf ported the assembler and the binutils to openVMS/Alpha.

 Steve Haworth contributed the support for the Texas Instruction c30
 (tms320c30).

 H.J. Lu has contributed many patches and much testing.

 Alan Modra reworked much of the i386 backend, improving the error
 checking, updating the code, and improving the 16 bit support, using
 patches from the work of Martynas Kunigelis and H.J. Lu.

 Many others have contributed large or small bugfixes and enhancements.  If
 you've contributed significant work and are not mentioned on this list, and
 want to be, let us know.  Some of the history has been lost; we aren't
 intentionally leaving anyone out.
