- ++++++++++++++++
-
- 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 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 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 proverbial 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.
-
- 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 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.
-
- The initial Alpha support was contributed by Carnegie-Mellon
- University. Additional work was done by Ken Raeburn of Cygnus
- Support. 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.
-
-
- 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.
