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 | raeburn@cygnus.com and I'll correct the situation. | |

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. | |

20 | K. Richard Pixley maintained gas for a while, adding various | |
f8ec0a45 RP |
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. | |

33 | Ken Raeburn currently maintains gas, and wrote the high-level BFD | |
34 | interface code to replace most of the code in format-specific I/O | |
35 | modules. | |

37 | The original Vax-VMS support was contributed by David L. Kashtan. |
38 | Eric Youngdale and Pat Rankin have done much work with it since. | |

40 | The Intel 80386 machine description was written by Eliot Dresselhaus. | |
41 | ||
42 | Minh Tran-Le at IntelliCorp contributed some AIX 386 support. | |
43 | ||
44 | The Motorola 88k machine description was contributed by Devon Bowen of | |
45 | Buffalo University and Torbjorn Granlund of the Swedish Institute of | |
46 | Computer Science. | |

48 | Keith Knowles at the Open Software Foundation wrote the original MIPS |
49 | back end (tc-mips.c, tc-mips.h), and contributed Rose format support | |
50 | that hasn't been merged in yet. Ralph Campbell worked with the MIPS | |
51 | code to support a.out format. | |

53 | Support 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 | |
06aa0337 ILT |
55 | (obj-ieee), was written by Steve Chamberlain of Cygnus Solutions. |
56 | Steve also modified the COFF back end (obj-coffbfd) to use BFD for | |
57 | some low-level operations, for use with the Hitachi, 29k and Zilog | |
58 | targets. | |

60 | John Gilmore built the AMD 29000 support, added .include support, and |
61 | simplified the configuration of which versions accept which | |
62 | pseudo-ops. He updated the 68k machine description so that Motorola's | |
63 | opcodes always produced fixed-size instructions (e.g. jsr), while | |
64 | synthetic instructions remained shrinkable (jbsr). John fixed many | |
65 | bugs, including true tested cross-compilation support, and one bug in | |
06aa0337 | 66 | relaxation that took a week and required the proverbial one-bit fix. |
1b1b6c02 | 67 | |
06aa0337 | 68 | Ian Lance Taylor of Cygnus Solutions merged the Motorola and MIT |
1b1b6c02 | 69 | syntaxes for the 68k, completed support for some COFF targets (68k, |
d43a0b2e ILT |
70 | i386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael |
71 | Meissner's mips-tfile program, wrote the PowerPC and RS/6000 support, | |
06aa0337 ILT |
72 | and made a few other minor patches. He handled the binutils releases |
73 | for versions 2.7 through 2.9. | |
74 | ||
75 | David Edelsohn contributed fixes for the PowerPC and AIX support. | |

77 | Steve Chamberlain made gas able to generate listings. | |

79 | Support for the HP9000/300 was contributed by Glenn Engel of HP. |
80 | ||
81 | Support for ELF format files has been worked on by Mark Eichin of | |
06aa0337 ILT |
82 | Cygnus Solutions (original, incomplete implementation), Pete |
83 | Hoogenboom at the University of Utah (HPPA mainly), Michael Meissner | |
84 | of the Open Software Foundation (i386 mainly), and Ken Raeburn of | |
85 | Cygnus Solutions (sparc, initial 64-bit support). | |
86 | ||
87 | Several engineers at Cygnus Solutions have also provided many small | |
88 | bug fixes and configuration enhancements. | |
89 | ||
90 | The initial Alpha support was contributed by Carnegie-Mellon | |
91 | University. Additional work was done by Ken Raeburn of Cygnus | |
92 | Solutions. Richard Henderson then rewrote much of the Alpha support. | |
93 | ||
94 | Ian Dall updated the support code for the National Semiconductor 32000 | |
95 | series, and added support for Mach 3 and NetBSD running on the PC532. | |
96 | ||
97 | Klaus Kaempf ported the assembler and the binutils to openVMS/Alpha. | |
98 | ||
99 | Steve Haworth contributed the support for the Texas Instruction c30 | |
100 | (tms320c30). | |
1b1b6c02 | 101 | |
06aa0337 | 102 | H.J. Lu has contributed many patches and much testing. |

104 | Alan Modra reworked much of the i386 backend, improving the error |
105 | checking and updating the code. | |

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. |
