1 (This file is under construction.) -*- text -*- 2 3 If you've contributed to gas and your name isn't listed here, it is 4 not meant as a slight. I just don't know about it. Email me, 5 nickc (a] redhat.com and I'll correct the situation. 6 7 This file will eventually be deleted: The general info will go into 8 the documentation, and info on specific files will go into an AUTHORS 9 file, as requested by the FSF. 10 11 ++++++++++++++++ 12 13 Dean Elsner wrote the original gas for vax. [more details?] 14 15 Jay Fenlason maintained gas for a while, adding support for 16 gdb-specific debug information and the 68k series machines, most of 17 the preprocessing pass, and extensive changes in messages.c, 18 input-file.c, write.c. 19 20 K. Richard Pixley maintained gas for a while, adding various 21 enhancements and many bug fixes, including merging support for several 22 processors, breaking gas up to handle multiple object file format 23 backends (including heavy rewrite, testing, an integration of the coff 24 and b.out backends), adding configuration including heavy testing and 25 verification of cross assemblers and file splits and renaming, 26 converted gas to strictly ansi C including full prototypes, added 27 support for m680[34]0 & cpu32, considerable work on i960 including a 28 coff port (including considerable amounts of reverse engineering), a 29 sparc opcode file rewrite, decstation, rs6000, and hp300hpux host 30 ports, updated "know" assertions and made them work, much other 31 reorganization, cleanup, and lint. 32 33 Ken Raeburn wrote the high-level BFD interface code to replace most of 34 the code in format-specific I/O modules. 35 36 The original Vax-VMS support was contributed by David L. Kashtan. 37 Eric Youngdale and Pat Rankin have done much work with it since. 38 39 The Intel 80386 machine description was written by Eliot Dresselhaus. 40 41 Minh Tran-Le at IntelliCorp contributed some AIX 386 support. 42 43 The Motorola 88k machine description was contributed by Devon Bowen of 44 Buffalo University and Torbjorn Granlund of the Swedish Institute of 45 Computer Science. 46 47 Keith Knowles at the Open Software Foundation wrote the original MIPS 48 back end (tc-mips.c, tc-mips.h), and contributed Rose format support 49 that hasn't been merged in yet. Ralph Campbell worked with the MIPS 50 code to support a.out format. 51 52 Support for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors 53 (tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format 54 (obj-ieee), was written by Steve Chamberlain of Cygnus Solutions. 55 Steve also modified the COFF back end (obj-coffbfd) to use BFD for 56 some low-level operations, for use with the Hitachi, 29k and Zilog 57 targets. 58 59 John Gilmore built the AMD 29000 support, added .include support, and 60 simplified the configuration of which versions accept which 61 pseudo-ops. He updated the 68k machine description so that Motorola's 62 opcodes always produced fixed-size instructions (e.g. jsr), while 63 synthetic instructions remained shrinkable (jbsr). John fixed many 64 bugs, including true tested cross-compilation support, and one bug in 65 relaxation that took a week and required the proverbial one-bit fix. 66 67 Ian Lance Taylor of Cygnus Solutions merged the Motorola and MIT 68 syntaxes for the 68k, completed support for some COFF targets (68k, 69 i386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael 70 Meissner's mips-tfile program, wrote the PowerPC and RS/6000 support, 71 and made a few other minor patches. He handled the binutils releases 72 for versions 2.7 through 2.9. 73 74 David Edelsohn contributed fixes for the PowerPC and AIX support. 75 76 Steve Chamberlain made gas able to generate listings. 77 78 Support for the HP9000/300 was contributed by Glenn Engel of HP. 79 80 Support for ELF format files has been worked on by Mark Eichin of 81 Cygnus Solutions (original, incomplete implementation), Pete 82 Hoogenboom at the University of Utah (HPPA mainly), Michael Meissner 83 of the Open Software Foundation (i386 mainly), and Ken Raeburn of 84 Cygnus Solutions (sparc, initial 64-bit support). 85 86 Several engineers at Cygnus Solutions have also provided many small 87 bug fixes and configuration enhancements. 88 89 The initial Alpha support was contributed by Carnegie-Mellon 90 University. Additional work was done by Ken Raeburn of Cygnus 91 Solutions. Richard Henderson then rewrote much of the Alpha support. 92 93 Ian Dall updated the support code for the National Semiconductor 32000 94 series, and added support for Mach 3 and NetBSD running on the PC532. 95 96 Klaus Kaempf ported the assembler and the binutils to openVMS/Alpha. 97 98 Steve Haworth contributed the support for the Texas Instruction c30 99 (tms320c30). 100 101 H.J. Lu has contributed many patches and much testing. 102 103 Alan Modra reworked much of the i386 backend, improving the error 104 checking, updating the code, and improving the 16 bit support, using 105 patches from the work of Martynas Kunigelis and H.J. Lu. 106 107 Many others have contributed large or small bugfixes and enhancements. If 108 you've contributed significant work and are not mentioned on this list, and 109 want to be, let us know. Some of the history has been lost; we aren't 110 intentionally leaving anyone out. 111 113 Copyright (C) 2012-2016 Free Software Foundation, Inc. 114 115 Copying and distribution of this file, with or without modification, 116 are permitted in any medium without royalty provided the copyright 117 notice and this notice are preserved. 118
