I just don't know about it. Email me, 589857Sobriennickc@redhat.com and I'll correct the situation. 633965Sjdp 733965SjdpThis file will eventually be deleted: The general info will go into 833965Sjdpthe documentation, and info on specific files will go into an AUTHORS 933965Sjdpfile, as requested by the FSF. 1033965Sjdp 1133965Sjdp++++++++++++++++ 1233965Sjdp 1333965SjdpDean Elsner wrote the original gas for vax. [more details?] 1433965Sjdp 1533965SjdpJay Fenlason maintained gas for a while, adding support for 1633965Sjdpgdb-specific debug information and the 68k series machines, most of 1733965Sjdpthe preprocessing pass, and extensive changes in messages.c, 1833965Sjdpinput-file.c, write.c. 1933965Sjdp 2033965SjdpK. Richard Pixley maintained gas for a while, adding various 2133965Sjdpenhancements and many bug fixes, including merging support for several 2233965Sjdpprocessors, breaking gas up to handle multiple object file format 2333965Sjdpbackends (including heavy rewrite, testing, an integration of the coff 2433965Sjdpand b.out backends), adding configuration including heavy testing and 2533965Sjdpverification of cross assemblers and file splits and renaming, 2633965Sjdpconverted gas to strictly ansi C including full prototypes, added 2733965Sjdpsupport for m680[34]0 & cpu32, considerable work on i960 including a 2833965Sjdpcoff port (including considerable amounts of reverse engineering), a 2933965Sjdpsparc opcode file rewrite, decstation, rs6000, and hp300hpux host 3033965Sjdpports, updated "know" assertions and made them work, much other 3133965Sjdpreorganization, cleanup, and lint. 3233965Sjdp 3333965SjdpKen Raeburn currently maintains gas, and wrote the high-level BFD 3433965Sjdpinterface code to replace most of the code in format-specific I/O 3533965Sjdpmodules. 3633965Sjdp 3733965SjdpThe original Vax-VMS support was contributed by David L. Kashtan. 3833965SjdpEric Youngdale and Pat Rankin have done much work with it since. 3933965Sjdp 4033965SjdpThe Intel 80386 machine description was written by Eliot Dresselhaus. 4133965Sjdp 4233965SjdpMinh Tran-Le at IntelliCorp contributed some AIX 386 support. 4333965Sjdp 4433965SjdpThe Motorola 88k machine description was contributed by Devon Bowen of 4533965SjdpBuffalo University and Torbjorn Granlund of the Swedish Institute of 4633965SjdpComputer Science. 4733965Sjdp 4833965SjdpKeith Knowles at the Open Software Foundation wrote the original MIPS 4933965Sjdpback end (tc-mips.c, tc-mips.h), and contributed Rose format support 5033965Sjdpthat hasn't been merged in yet. Ralph Campbell worked with the MIPS 5133965Sjdpcode to support a.out format. 5233965Sjdp 5333965SjdpSupport for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors 5433965Sjdp(tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format 5538889Sjdp(obj-ieee), was written by Steve Chamberlain of Cygnus Solutions. 5638889SjdpSteve also modified the COFF back end (obj-coffbfd) to use BFD for 5738889Sjdpsome low-level operations, for use with the Hitachi, 29k and Zilog 5838889Sjdptargets. 5933965Sjdp 6033965SjdpJohn Gilmore built the AMD 29000 support, added .include support, and 6133965Sjdpsimplified the configuration of which versions accept which 6233965Sjdppseudo-ops. He updated the 68k machine description so that Motorola's 6333965Sjdpopcodes always produced fixed-size instructions (e.g. jsr), while 6433965Sjdpsynthetic instructions remained shrinkable (jbsr). John fixed many 6533965Sjdpbugs, including true tested cross-compilation support, and one bug in 6633965Sjdprelaxation that took a week and required the proverbial one-bit fix. 6733965Sjdp 6838889SjdpIan Lance Taylor of Cygnus Solutions merged the Motorola and MIT 6933965Sjdpsyntaxes for the 68k, completed support for some COFF targets (68k, 7033965Sjdpi386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael 7133965SjdpMeissner's mips-tfile program, wrote the PowerPC and RS/6000 support, 7260484Sobrienand made a few other minor patches. He handled the binutils releases 7360484Sobrienfor versions 2.7 through 2.9. 7433965Sjdp 7533965SjdpDavid Edelsohn contributed fixes for the PowerPC and AIX support. 7633965Sjdp 7733965SjdpSteve Chamberlain made gas able to generate listings. 7833965Sjdp 7933965SjdpSupport for the HP9000/300 was contributed by Glenn Engel of HP. 8033965Sjdp 8133965SjdpSupport for ELF format files has been worked on by Mark Eichin of 8238889SjdpCygnus Solutions (original, incomplete implementation), Pete 8338889SjdpHoogenboom at the University of Utah (HPPA mainly), Michael Meissner 8438889Sjdpof the Open Software Foundation (i386 mainly), and Ken Raeburn of 8538889SjdpCygnus Solutions (sparc, initial 64-bit support). 8633965Sjdp 8738889SjdpSeveral engineers at Cygnus Solutions have also provided many small 8838889Sjdpbug fixes and configuration enhancements. 8933965Sjdp 9033965SjdpThe initial Alpha support was contributed by Carnegie-Mellon 9133965SjdpUniversity. Additional work was done by Ken Raeburn of Cygnus 9238889SjdpSolutions. Richard Henderson then rewrote much of the Alpha support. 9333965Sjdp 9433965SjdpIan Dall updated the support code for the National Semiconductor 32000 9533965Sjdpseries, and added support for Mach 3 and NetBSD running on the PC532. 9633965Sjdp 9733965SjdpKlaus Kaempf ported the assembler and the binutils to openVMS/Alpha. 9833965Sjdp 9938889SjdpSteve Haworth contributed the support for the Texas Instruction c30 10038889Sjdp(tms320c30). 10138889Sjdp 10260484SobrienH.J. Lu has contributed many patches and much testing. 10360484Sobrien 10460484SobrienAlan Modra reworked much of the i386 backend, improving the error 10560484Sobrienchecking, updating the code, and improving the 16 bit support, using 10660484Sobrienpatches from the work of Martynas Kunigelis and H.J. Lu. 10760484Sobrien 10833965SjdpMany others have contributed large or small bugfixes and enhancements.
