3If you've contributed to gas and your name isn't listed here, it is
4not meant as a slight.  I just don't know about it.  Email me,
5raeburn@cygnus.com and I'll correct the situation.

13Dean Elsner wrote the original gas for vax.  [more details?]
14
15Jay Fenlason maintained gas for a while, adding support for
16gdb-specific debug information and the 68k series machines, most of
17the preprocessing pass, and extensive changes in messages.c,
18input-file.c, write.c.
19
20K. Richard Pixley maintained gas for a while, adding various
21enhancements and many bug fixes, including merging support for several
22processors, breaking gas up to handle multiple object file format
23backends (including heavy rewrite, testing, an integration of the coff
24and b.out backends), adding configuration including heavy testing and
25verification of cross assemblers and file splits and renaming,
26converted gas to strictly ansi C including full prototypes, added
27support for m680[34]0 & cpu32, considerable work on i960 including a
28coff port (including considerable amounts of reverse engineering), a
29sparc opcode file rewrite, decstation, rs6000, and hp300hpux host
30ports, updated "know" assertions and made them work, much other
31reorganization, cleanup, and lint.
32
33Ken Raeburn currently maintains gas, and wrote the high-level BFD
34interface code to replace most of the code in format-specific I/O
35modules.
36
37The original Vax-VMS support was contributed by David L. Kashtan.
38Eric Youngdale and Pat Rankin have done much work with it since.
39
40The Intel 80386 machine description was written by Eliot Dresselhaus.
41
42Minh Tran-Le at IntelliCorp contributed some AIX 386 support.
43
44The Motorola 88k machine description was contributed by Devon Bowen of
45Buffalo University and Torbjorn Granlund of the Swedish Institute of
46Computer Science.
47
48Keith Knowles at the Open Software Foundation wrote the original MIPS
49back end (tc-mips.c, tc-mips.h), and contributed Rose format support
50that hasn't been merged in yet.  Ralph Campbell worked with the MIPS
51code to support a.out format.
52
53Support for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors
54(tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format
55(obj-ieee), was written by Steve Chamberlain of Cygnus Support.  Steve
56also modified the COFF back end (obj-coffbfd) to use BFD for some
57low-level operations, for use with the Hitachi, 29k and Zilog targets.
58
59John Gilmore built the AMD 29000 support, added .include support, and
60simplified the configuration of which versions accept which
61pseudo-ops.  He updated the 68k machine description so that Motorola's
62opcodes always produced fixed-size instructions (e.g. jsr), while
63synthetic instructions remained shrinkable (jbsr).  John fixed many
64bugs, including true tested cross-compilation support, and one bug in
65relaxation that took a week and required the proverbial one-bit fix.
66
67Ian Lance Taylor of Cygnus Support merged the Motorola and MIT
68syntaxes for the 68k, completed support for some COFF targets (68k,
69i386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael
70Meissner's mips-tfile program, wrote the PowerPC and RS/6000 support,
71and made a few other minor patches.
72
73David Edelsohn contributed fixes for the PowerPC and AIX support.
74
75Steve Chamberlain made gas able to generate listings.
76
77Support for the HP9000/300 was contributed by Glenn Engel of HP.
78
79Support for ELF format files has been worked on by Mark Eichin of
80Cygnus Support (original, incomplete implementation), Pete Hoogenboom
81at the University of Utah (HPPA mainly), Michael Meissner of the Open
82Software Foundation (i386 mainly), and Ken Raeburn of Cygnus Support
83(sparc, initial 64-bit support).
84
85Several engineers at Cygnus Support have also provided many small bug
86fixes and configuration enhancements.
87
88The initial Alpha support was contributed by Carnegie-Mellon
89University.  Additional work was done by Ken Raeburn of Cygnus
90Support.  Richard Henderson then rewrote much of the Alpha support.
91
92Ian Dall updated the support code for the National Semiconductor 32000
93series, and added support for Mach 3 and NetBSD running on the PC532.
94
95Klaus Kaempf ported the assembler and the binutils to openVMS/Alpha.
96
97Many others have contributed large or small bugfixes and enhancements.  If
98you've contributed significant work and are not mentioned on this list, and
99want to be, let us know.  Some of the history has been lost; we aren't
100intentionally leaving anyone out.
