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

This file will eventually be deleted: The general info will go into

the documentation, and info on specific files will go into an AUTHORS

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 currently maintains gas, and wrote the high-level BFD
|
|
interface code to replace most of the code in format-specific I/O
|
|
modules.
|
|
|
|
The original VMS support was contributed by David L. Kashtan. Eric
|
|
Youngdale has 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 Support. 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 apocryphal one-bit fix.
|
|
|
|
Ian Lance Taylor of Cygnus Support 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.
|
|
|
|
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 Support (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 Support
|
|
(sparc, initial 64-bit support).
|
|
|
|
Several engineers at Cygnus Support have also provided many small bug
|
|
fixes and configuration enhancements.
|
|
|
|
|
|
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.
