Chapter 44.AcknowledgementsIf you have contributed to as and your name isn’t listed here, it is not meant as a slight. We just don’tknow about it. Send mail to the maintainer, and we’ll correct the situation. Currently the maintainer isKen Raeburn (email address raeburn@cygnus.com).Dean Elsner wrote the original gnu assembler for the VAX.1Jay Fenlason maintained GAS for a while, adding support for GDB-specific debug information andthe 68k series machines, most of the preprocessing pass, and extensive changes in messages.c,input-file.c, write.c.K. Richard Pixley maintained GAS for a while, adding various enhancements and many bug fixes,including merging support for several processors, breaking GAS up to handle multiple object fileformat back ends (including heavy rewrite, testing, an integration of the coff and b.out back ends),adding configuration including heavy testing and verification of cross assemblers and file splits andrenaming, converted GAS to strictly ANSI C including full prototypes, added support for m680[34]0and cpu32, did considerable work on i960 including a COFF port (including considerable amounts ofreverse engineering), a SPARC opcode file rewrite, DECstation, rs6000, and hp300hpux host ports,updated "know" assertions and made them work, much other reorganization, cleanup, and lint.Ken Raeburn wrote the high-level BFD interface code to replace most of the code in format-specificI/O modules.The original VMS support was contributed by David L. Kashtan. Eric Youngdale has done much workwith it since.The Intel 80386 machine description was written by Eliot Dresselhaus.Minh Tran-Le at IntelliCorp contributed some AIX 386 support.The Motorola 88k machine description was contributed by Devon Bowen of Buffalo University andTorbjorn Granlund of the Swedish Institute of Computer Science.Keith Knowles at the Open Software Foundation wrote the original MIPS back end (tc-mips.c,tc-mips.h), and contributed Rose format support (which hasn’t been merged in yet). Ralph Camp-bell worked with the MIPS code to support a.out format.Support for the Zilog Z8k and Renesas H8/300 and H8/500 processors (tc-z8k, tc-h8300, tc-h8500),and IEEE 695 object file format (obj-ieee), was written by Steve Chamberlain of Cygnus Support.Steve also modified the COFF back end to use BFD for some low-level operations, for use with theH8/300 and AMD 29k targets.John Gilmore built the AMD 29000 support, added .include support, and simplified the config-uration of which versions accept which directives. He updated the 68k machine description so thatMotorola’s opcodes always produced fixed-size instructions (e.g., jsr), while synthetic instructionsremained shrinkable (jbsr). John fixed many bugs, including true tested cross-compilation support,and one bug in relaxation that took a week and required the proverbial one-bit fix.Ian Lance Taylor of Cygnus Support merged the Motorola and MIT syntax for the 68k, completedsupport for some COFF targets (68k, i386 SVR3, and SCO Unix), added support for MIPS ECOFFand ELF targets, wrote the initial RS/6000 and PowerPC assembler, and made a few other minorpatches.Steve Chamberlain made as able to generate listings.Hewlett-Packard contributed support for the HP9000/300.1.
