  2. If you've contributed to gas and your name isn't listed here, it is
  3. not meant as a slight. I just don't know about it. Email me,
  4. nickc@redhat.com and I'll correct the situation.
  5. This file will eventually be deleted: The general info will go into
  6. the documentation, and info on specific files will go into an AUTHORS
  7. file, as requested by the FSF.

  9. Dean Elsner wrote the original gas for vax. [more details?]
  10. Jay Fenlason maintained gas for a while, adding support for
  11. gdb-specific debug information and the 68k series machines, most of
  12. the preprocessing pass, and extensive changes in messages.c,
  13. input-file.c, write.c.
  14. K. Richard Pixley maintained gas for a while, adding various
  15. enhancements and many bug fixes, including merging support for several
  16. processors, breaking gas up to handle multiple object file format
  17. backends (including heavy rewrite, testing, an integration of the coff
  18. and b.out backends), adding configuration including heavy testing and
  19. verification of cross assemblers and file splits and renaming,
  20. converted gas to strictly ansi C including full prototypes, added
  21. support for m680[34]0 & cpu32, considerable work on i960 including a
  22. coff port (including considerable amounts of reverse engineering), a
  23. sparc opcode file rewrite, decstation, rs6000, and hp300hpux host
  24. ports, updated "know" assertions and made them work, much other
  25. reorganization, cleanup, and lint.
  26. Ken Raeburn wrote the high-level BFD interface code to replace most of
  27. the code in format-specific I/O modules.
  28. The original Vax-VMS support was contributed by David L. Kashtan.
  29. Eric Youngdale and Pat Rankin have done much work with it since.
  30. The Intel 80386 machine description was written by Eliot Dresselhaus.
  31. Minh Tran-Le at IntelliCorp contributed some AIX 386 support.
  32. The Motorola 88k machine description was contributed by Devon Bowen of
  33. Buffalo University and Torbjorn Granlund of the Swedish Institute of
  34. Computer Science.
  35. Keith Knowles at the Open Software Foundation wrote the original MIPS
  36. back end (tc-mips.c, tc-mips.h), and contributed Rose format support
  37. that hasn't been merged in yet. Ralph Campbell worked with the MIPS
  38. code to support a.out format.
  39. Support for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors
  40. (tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format
  41. (obj-ieee), was written by Steve Chamberlain of Cygnus Solutions.
  42. Steve also modified the COFF back end (obj-coffbfd) to use BFD for
  43. some low-level operations, for use with the Hitachi, 29k and Zilog
  44. targets.
  45. John Gilmore built the AMD 29000 support, added .include support, and
  46. simplified the configuration of which versions accept which
  47. pseudo-ops. He updated the 68k machine description so that Motorola's
  48. opcodes always produced fixed-size instructions (e.g. jsr), while
  49. synthetic instructions remained shrinkable (jbsr). John fixed many
  50. bugs, including true tested cross-compilation support, and one bug in
  51. relaxation that took a week and required the proverbial one-bit fix.
  52. Ian Lance Taylor of Cygnus Solutions merged the Motorola and MIT
  53. syntaxes for the 68k, completed support for some COFF targets (68k,
  54. i386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael
  55. Meissner's mips-tfile program, wrote the PowerPC and RS/6000 support,
  56. and made a few other minor patches. He handled the binutils releases
  57. for versions 2.7 through 2.9.
  58. David Edelsohn contributed fixes for the PowerPC and AIX support.
  59. Steve Chamberlain made gas able to generate listings.
  60. Support for the HP9000/300 was contributed by Glenn Engel of HP.
  61. Support for ELF format files has been worked on by Mark Eichin of
  62. Cygnus Solutions (original, incomplete implementation), Pete
  63. Hoogenboom at the University of Utah (HPPA mainly), Michael Meissner
  64. of the Open Software Foundation (i386 mainly), and Ken Raeburn of
  65. Cygnus Solutions (sparc, initial 64-bit support).
  66. Several engineers at Cygnus Solutions have also provided many small
  67. bug fixes and configuration enhancements.
  68. The initial Alpha support was contributed by Carnegie-Mellon
  69. University. Additional work was done by Ken Raeburn of Cygnus
  70. Solutions. Richard Henderson then rewrote much of the Alpha support.
  71. Ian Dall updated the support code for the National Semiconductor 32000
  72. series, and added support for Mach 3 and NetBSD running on the PC532.
  73. Klaus Kaempf ported the assembler and the binutils to openVMS/Alpha.
  74. Steve Haworth contributed the support for the Texas Instruction c30
  75. (tms320c30).
  76. H.J. Lu has contributed many patches and much testing.
  77. Alan Modra reworked much of the i386 backend, improving the error
  78. checking, updating the code, and improving the 16 bit support, using
  79. patches from the work of Martynas Kunigelis and H.J. Lu.
  80. Many others have contributed large or small bugfixes and enhancements. If
  81. you've contributed significant work and are not mentioned on this list, and
  82. want to be, let us know. Some of the history has been lost; we aren't
  83. intentionally leaving anyone out.
