[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 33130561SobrienKen Raeburn wrote the high-level BFD interface code to replace most of 34130561Sobrienthe code in format-specific I/O modules. 3533965Sjdp 3633965SjdpThe original Vax-VMS support was contributed by David L. Kashtan. 3733965SjdpEric Youngdale and Pat Rankin have done much work with it since. 3833965Sjdp 3933965SjdpThe Intel 80386 machine description was written by Eliot Dresselhaus. 4033965Sjdp 4133965SjdpMinh Tran-Le at IntelliCorp contributed some AIX 386 support. 4233965Sjdp 4333965SjdpThe Motorola 88k machine description was contributed by Devon Bowen of 4433965SjdpBuffalo University and Torbjorn Granlund of the Swedish Institute of 4533965SjdpComputer Science. 4633965Sjdp 4733965SjdpKeith Knowles at the Open Software Foundation wrote the original MIPS 4833965Sjdpback end (tc-mips.c, tc-mips.h), and contributed Rose format support 4933965Sjdpthat hasn't been merged in yet. Ralph Campbell worked with the MIPS 5033965Sjdpcode to support a.out format. 5133965Sjdp 5233965SjdpSupport for the Zilog Z8k and Hitachi H8/300, H8/500 and SH processors 5333965Sjdp(tc-z8k, tc-h8300, tc-h8500, tc-sh), and IEEE 695 object file format 5438889Sjdp(obj-ieee), was written by Steve Chamberlain of Cygnus Solutions. 5538889SjdpSteve also modified the COFF back end (obj-coffbfd) to use BFD for 5638889Sjdpsome low-level operations, for use with the Hitachi, 29k and Zilog 5738889Sjdptargets. 5833965Sjdp 5933965SjdpJohn Gilmore built the AMD 29000 support, added .include support, and 6033965Sjdpsimplified the configuration of which versions accept which 6133965Sjdppseudo-ops. He updated the 68k machine description so that Motorola's 6233965Sjdpopcodes always produced fixed-size instructions (e.g. jsr), while 6333965Sjdpsynthetic instructions remained shrinkable (jbsr). John fixed many 6433965Sjdpbugs, including true tested cross-compilation support, and one bug in 6533965Sjdprelaxation that took a week and required the proverbial one-bit fix. 6633965Sjdp 6738889SjdpIan Lance Taylor of Cygnus Solutions merged the Motorola and MIT 6833965Sjdpsyntaxes for the 68k, completed support for some COFF targets (68k, 6933965Sjdpi386 SVR3, and SCO Unix), wrote the ECOFF support based on Michael 7033965SjdpMeissner's mips-tfile program, wrote the PowerPC and RS/6000 support, 7160484Sobrienand made a few other minor patches. He handled the binutils releases 7260484Sobrienfor versions 2.7 through 2.9. 7333965Sjdp 7433965SjdpDavid Edelsohn contributed fixes for the PowerPC and AIX support. 7533965Sjdp 7633965SjdpSteve Chamberlain made gas able to generate listings. 7733965Sjdp 7833965SjdpSupport for the HP9000/300 was contributed by Glenn Engel of HP. 7933965Sjdp 8033965SjdpSupport for ELF format files has been worked on by Mark Eichin of 8138889SjdpCygnus Solutions (original, incomplete implementation), Pete 8238889SjdpHoogenboom at the University of Utah (HPPA mainly), Michael Meissner 8338889Sjdpof the Open Software Foundation (i386 mainly), and Ken Raeburn of 8438889SjdpCygnus Solutions (sparc, initial 64-bit support). 8533965Sjdp 8638889SjdpSeveral engineers at Cygnus Solutions have also provided many small 8738889Sjdpbug fixes and configuration enhancements. 8833965Sjdp 8933965SjdpThe initial Alpha support was contributed by Carnegie-Mellon 9033965SjdpUniversity. Additional work was done by Ken Raeburn of Cygnus 9138889SjdpSolutions. Richard Henderson then rewrote much of the Alpha support. 9233965Sjdp 9333965SjdpIan Dall updated the support code for the National Semiconductor 32000 9433965Sjdpseries, and added support for Mach 3 and NetBSD running on the PC532. 9533965Sjdp 9633965SjdpKlaus Kaempf ported the assembler and the binutils to openVMS/Alpha. 9733965Sjdp 9838889SjdpSteve Haworth contributed the support for the Texas Instruction c30 9938889Sjdp(tms320c30). 10038889Sjdp 10160484SobrienH.J. Lu has contributed many patches and much testing. 10260484Sobrien 10360484SobrienAlan Modra reworked much of the i386 backend, improving the error 10460484Sobrienchecking, updating the code, and improving the 16 bit support, using 10560484Sobrienpatches from the work of Martynas Kunigelis and H.J. Lu. 10660484Sobrien 10733965SjdpMany others have contributed large or small bugfixes and enhancements.
