[more details?] 14153537Sdougb 1598184SgordonJay Fenlason maintained gas for a while, adding support for 1698184Sgordongdb-specific debug information and the 68k series machines, most of 1798184Sgordonthe preprocessing pass, and extensive changes in messages.c, 1898184Sgordoninput-file.c, write.c. 1998184Sgordon 2098184SgordonK. Richard Pixley maintained gas for a while, adding various 2198184Sgordonenhancements and many bug fixes, including merging support for several 2298184Sgordonprocessors, breaking gas up to handle multiple object file format 2398184Sgordonbackends (including heavy rewrite, testing, an integration of the coff 2498184Sgordonand b.out backends), adding configuration including heavy testing and 2598184Sgordonverification of cross assemblers and file splits and renaming, 2698184Sgordonconverted gas to strictly ansi C including full prototypes, added 2798184Sgordonsupport for m680[34]0 & cpu32, considerable work on i960 including a 2898184Sgordoncoff port (including considerable amounts of reverse engineering), a 2998184Sgordonsparc opcode file rewrite, decstation, rs6000, and hp300hpux host 30154787Snetchildports, updated "know" assertions and made them work, much other 31154236Sbrooksreorganization, cleanup, and lint. 32154236Sbrooks 33154236SbrooksKen Raeburn wrote the high-level BFD interface code to replace most of 34154236Sbrooksthe code in format-specific I/O modules. 35154236Sbrooks 36154236SbrooksThe original Vax-VMS support was contributed by David L. Kashtan. 3798184SgordonEric Youngdale and Pat Rankin have done much work with it since. 3898184Sgordon 3998184SgordonThe Intel 80386 machine description was written by Eliot Dresselhaus. 40153537Sdougb 41153537SdougbMinh Tran-Le at IntelliCorp contributed some AIX 386 support. 42153537Sdougb 43153537SdougbThe Motorola 88k machine description was contributed by Devon Bowen of 44153537SdougbBuffalo University and Torbjorn Granlund of the Swedish Institute of 4598184SgordonComputer Science. 46153537Sdougb 47153537SdougbKeith Knowles at the Open Software Foundation wrote the original MIPS 48153537Sdougbback end (tc-mips.c, tc-mips.h), and contributed Rose format support 49153537Sdougbthat hasn't been merged in yet. Ralph Campbell worked with the MIPS 50153537Sdougbcode to support a.out format. 51153537Sdougb 52153537SdougbSupport for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors 53153537Sdougb(tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format 54153537Sdougb(obj-ieee), was written by Steve Chamberlain of Cygnus Solutions. 55153537SdougbSteve also modified the COFF back end (obj-coffbfd) to use BFD for 56153537Sdougbsome low-level operations, for use with the Hitachi, 29k and Zilog 5798184Sgordontargets. 5898184Sgordon 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 Solutions 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. He handled the binutils releases 72for versions 2.7 through 2.9. 73 74David Edelsohn contributed fixes for the PowerPC and AIX support. 75 76Steve Chamberlain made gas able to generate listings. 77 78Support for the HP9000/300 was contributed by Glenn Engel of HP. 79 80Support for ELF format files has been worked on by Mark Eichin of 81Cygnus Solutions (original, incomplete implementation), Pete 82Hoogenboom at the University of Utah (HPPA mainly), Michael Meissner 83of the Open Software Foundation (i386 mainly), and Ken Raeburn of 84Cygnus Solutions (sparc, initial 64-bit support). 85 86Several engineers at Cygnus Solutions have also provided many small 87bug fixes and configuration enhancements. 88 89The initial Alpha support was contributed by Carnegie-Mellon 90University. Additional work was done by Ken Raeburn of Cygnus 91Solutions. Richard Henderson then rewrote much of the Alpha support. 92 93Ian Dall updated the support code for the National Semiconductor 32000 94series, and added support for Mach 3 and NetBSD running on the PC532. 95 96Klaus Kaempf ported the assembler and the binutils to openVMS/Alpha. 97 98Steve Haworth contributed the support for the Texas Instruction c30 99(tms320c30). 100 101H.J. Lu has contributed many patches and much testing. 102 103Alan Modra reworked much of the i386 backend, improving the error 104checking, updating the code, and improving the 16 bit support, using 105patches from the work of Martynas Kunigelis and H.J. Lu. 106 107Many others have contributed large or small bugfixes and enhancements. If 108you've contributed significant work and are not mentioned on this list, and 109want to be, let us know. Some of the history has been lost; we aren't 110intentionally leaving anyone out. 111
