| 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. |
