CONTRIBUTORS revision 60484
1(This file is under construction.) -*- text -*- 2 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. 6 7This file will eventually be deleted: The general info will go into 8the documentation, and info on specific files will go into an AUTHORS 9file, as requested by the FSF. 10 11++++++++++++++++ 12 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 Solutions. 56Steve also modified the COFF back end (obj-coffbfd) to use BFD for 57some low-level operations, for use with the Hitachi, 29k and Zilog 58targets. 59 60John Gilmore built the AMD 29000 support, added .include support, and 61simplified the configuration of which versions accept which 62pseudo-ops. He updated the 68k machine description so that Motorola's 63opcodes always produced fixed-size instructions (e.g. jsr), while 64synthetic instructions remained shrinkable (jbsr). John fixed many 65bugs, including true tested cross-compilation support, and one bug in 66relaxation that took a week and required the proverbial one-bit fix. 67 68Ian Lance Taylor of Cygnus Solutions merged the Motorola and MIT 69syntaxes for the 68k, completed support for some COFF targets (68k, 70i386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael 71Meissner's mips-tfile program, wrote the PowerPC and RS/6000 support, 72and made a few other minor patches. He handled the binutils releases 73for versions 2.7 through 2.9. 74 75David Edelsohn contributed fixes for the PowerPC and AIX support. 76 77Steve Chamberlain made gas able to generate listings. 78 79Support for the HP9000/300 was contributed by Glenn Engel of HP. 80 81Support for ELF format files has been worked on by Mark Eichin of 82Cygnus Solutions (original, incomplete implementation), Pete 83Hoogenboom at the University of Utah (HPPA mainly), Michael Meissner 84of the Open Software Foundation (i386 mainly), and Ken Raeburn of 85Cygnus Solutions (sparc, initial 64-bit support). 86 87Several engineers at Cygnus Solutions have also provided many small 88bug fixes and configuration enhancements. 89 90The initial Alpha support was contributed by Carnegie-Mellon 91University. Additional work was done by Ken Raeburn of Cygnus 92Solutions. Richard Henderson then rewrote much of the Alpha support. 93 94Ian Dall updated the support code for the National Semiconductor 32000 95series, and added support for Mach 3 and NetBSD running on the PC532. 96 97Klaus Kaempf ported the assembler and the binutils to openVMS/Alpha. 98 99Steve Haworth contributed the support for the Texas Instruction c30 100(tms320c30). 101 102H.J. Lu has contributed many patches and much testing. 103 104Alan Modra reworked much of the i386 backend, improving the error 105checking, updating the code, and improving the 16 bit support, using 106patches from the work of Martynas Kunigelis and H.J. Lu. 107 108Many others have contributed large or small bugfixes and enhancements. If 109you've contributed significant work and are not mentioned on this list, and 110want to be, let us know. Some of the history has been lost; we aren't 111intentionally leaving anyone out. 112
