I just don't know about it. Email me, 5227652Sgrehannickc@redhat.com and I'll correct the situation. 6227652Sgrehan 7227652SgrehanThis file will eventually be deleted: The general info will go into 8227652Sgrehanthe documentation, and info on specific files will go into an AUTHORS 9227652Sgrehanfile, as requested by the FSF. 10227652Sgrehan 11227652Sgrehan++++++++++++++++ 12227652Sgrehan 13227652SgrehanDean Elsner wrote the original gas for vax. [more details?] 14227652Sgrehan 15227652SgrehanJay Fenlason maintained gas for a while, adding support for 16227652Sgrehangdb-specific debug information and the 68k series machines, most of 17227652Sgrehanthe preprocessing pass, and extensive changes in messages.c, 18227652Sgrehaninput-file.c, write.c. 19227652Sgrehan 20227652SgrehanK. Richard Pixley maintained gas for a while, adding various 21227652Sgrehanenhancements and many bug fixes, including merging support for several 22227652Sgrehanprocessors, breaking gas up to handle multiple object file format 23227652Sgrehanbackends (including heavy rewrite, testing, an integration of the coff 24227652Sgrehanand b.out backends), adding configuration including heavy testing and 25227652Sgrehanverification of cross assemblers and file splits and renaming, 26227652Sgrehanconverted gas to strictly ansi C including full prototypes, added 27227652Sgrehansupport for m680[34]0 & cpu32, considerable work on i960 including a 28227652Sgrehancoff port (including considerable amounts of reverse engineering), a 29227652Sgrehansparc opcode file rewrite, decstation, rs6000, and hp300hpux host 30227652Sgrehanports, updated "know" assertions and made them work, much other 31227652Sgrehanreorganization, cleanup, and lint. 32227652Sgrehan 33227652SgrehanKen Raeburn wrote the high-level BFD interface code to replace most of 34227652Sgrehanthe code in format-specific I/O modules. 35227652Sgrehan 36227652SgrehanThe original Vax-VMS support was contributed by David L. Kashtan. 37227652SgrehanEric Youngdale and Pat Rankin have done much work with it since. 38227652Sgrehan 39227652SgrehanThe Intel 80386 machine description was written by Eliot Dresselhaus. 40227652Sgrehan 41227652SgrehanMinh Tran-Le at IntelliCorp contributed some AIX 386 support. 42227652Sgrehan 43227652SgrehanThe Motorola 88k machine description was contributed by Devon Bowen of 44227652SgrehanBuffalo University and Torbjorn Granlund of the Swedish Institute of 45227652SgrehanComputer Science. 46227652Sgrehan 47227652SgrehanKeith Knowles at the Open Software Foundation wrote the original MIPS 48227652Sgrehanback end (tc-mips.c, tc-mips.h), and contributed Rose format support 49227652Sgrehanthat hasn't been merged in yet. Ralph Campbell worked with the MIPS 50227652Sgrehancode to support a.out format. 51227652Sgrehan 52227652SgrehanSupport for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors 53227652Sgrehan(tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format 54227652Sgrehan(obj-ieee), was written by Steve Chamberlain of Cygnus Solutions. 55227652SgrehanSteve also modified the COFF back end (obj-coffbfd) to use BFD for 56227652Sgrehansome low-level operations, for use with the Hitachi, 29k and Zilog 57227652Sgrehantargets. 58227652Sgrehan 59227652SgrehanJohn Gilmore built the AMD 29000 support, added .include support, and 60227652Sgrehansimplified the configuration of which versions accept which 61227652Sgrehanpseudo-ops. He updated the 68k machine description so that Motorola's 62227652Sgrehanopcodes always produced fixed-size instructions (e.g. jsr), while 63227652Sgrehansynthetic instructions remained shrinkable (jbsr). John fixed many 64227652Sgrehanbugs, including true tested cross-compilation support, and one bug in 65227652Sgrehanrelaxation that took a week and required the proverbial one-bit fix. 66227652Sgrehan 67227652SgrehanIan Lance Taylor of Cygnus Solutions merged the Motorola and MIT 68227652Sgrehansyntaxes for the 68k, completed support for some COFF targets (68k, 69227652Sgrehani386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael 70227652SgrehanMeissner's mips-tfile program, wrote the PowerPC and RS/6000 support, 71227652Sgrehanand made a few other minor patches. He handled the binutils releases 72227652Sgrehanfor versions 2.7 through 2.9. 73227652Sgrehan 74227652SgrehanDavid Edelsohn contributed fixes for the PowerPC and AIX support. 75227652Sgrehan 76227652SgrehanSteve Chamberlain made gas able to generate listings. 77227652Sgrehan 78227652SgrehanSupport for the HP9000/300 was contributed by Glenn Engel of HP. 79227652Sgrehan 80227652SgrehanSupport for ELF format files has been worked on by Mark Eichin of 81227652SgrehanCygnus Solutions (original, incomplete implementation), Pete 82227652SgrehanHoogenboom at the University of Utah (HPPA mainly), Michael Meissner 83227652Sgrehanof the Open Software Foundation (i386 mainly), and Ken Raeburn of 84227652SgrehanCygnus Solutions (sparc, initial 64-bit support). 85227652Sgrehan 86227652SgrehanSeveral engineers at Cygnus Solutions have also provided many small 87227652Sgrehanbug fixes and configuration enhancements. 88227652Sgrehan 89227652SgrehanThe initial Alpha support was contributed by Carnegie-Mellon 90227652SgrehanUniversity. Additional work was done by Ken Raeburn of Cygnus 91227652SgrehanSolutions. Richard Henderson then rewrote much of the Alpha support. 92227652Sgrehan 93227652SgrehanIan Dall updated the support code for the National Semiconductor 32000 94227652Sgrehanseries, and added support for Mach 3 and NetBSD running on the PC532. 95227652Sgrehan 96227652SgrehanKlaus Kaempf ported the assembler and the binutils to openVMS/Alpha. 97227652Sgrehan 98227652SgrehanSteve Haworth contributed the support for the Texas Instruction c30 99227652Sgrehan(tms320c30). 100227652Sgrehan 101227652SgrehanH.J. Lu has contributed many patches and much testing. 102227652Sgrehan 103227652SgrehanAlan Modra reworked much of the i386 backend, improving the error 104227652Sgrehanchecking, updating the code, and improving the 16 bit support, using 105227652Sgrehanpatches from the work of Martynas Kunigelis and H.J. Lu. 106227652Sgrehan 107227652SgrehanMany others have contributed large or small bugfixes and enhancements. If 108227652Sgrehanyou've contributed significant work and are not mentioned on this list, and 109227652Sgrehanwant to be, let us know. Some of the history has been lost; we aren't 110227652Sgrehanintentionally leaving anyone out. 111227652Sgrehan
