|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,
|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 m6800 & 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
|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
|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
|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.
