| If you have contributed to `as' and your name isn't listed here, it |
| is not meant as a slight. We just don't know about it. Send mail to |
| the maintainer, and we'll correct the situation. Currently the |
| maintainer is Ken Raeburn (email address `raeburn@cygnus.com'). |
| |
| Dean Elsner wrote the original GNU assembler for the VAX.(1) |
| |
| Jay Fenlason maintained GAS for a while, adding support for |
| GDB-specific debug information and the 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 file format 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 and renaming, |
| converted GAS to strictly ANSI C including full prototypes, added |
| support for m680[34]0 and cpu32, did considerable work on i960 |
| including a COFF port (including considerable amounts of reverse |
| 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-specific I/O modules. |
| |
| The original VMS support was contributed by David L. Kashtan. Eric |
| Youngdale has done much work with 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 and Torbjorn 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 Campbell 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 the H8/300 and AMD 29k targets. |
| |
| John Gilmore built the AMD 29000 support, added `.include' support, |
| and simplified the configuration of which versions accept which |
| directives. He updated the 68k machine description so that Motorola's |
| opcodes always produced fixed-size instructions (e.g., `jsr'), while |
| synthetic instructions remained 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, completed support for some COFF targets (68k, i386 |
| SVR3, and SCO Unix), added support for MIPS ECOFF and ELF targets, |
| wrote the initial RS/6000 and PowerPC assembler, and made a few other |
| minor patches. |
| |
| Steve Chamberlain made `as' able to generate listings. |
| |
| Hewlett-Packard contributed support for the HP9000/300. |
| |
| Jeff Law wrote GAS and BFD support for the native HPPA object format |
| (SOM) along with a fairly extensive HPPA testsuite (for both SOM and |
| ELF object formats). This work was supported by both the Center for |
| Software Science at the University of Utah and Cygnus Support. |
| |
| Support for ELF format files has been worked on by Mark Eichin of |
| Cygnus Support (original, incomplete implementation for SPARC), Pete |
| Hoogenboom and Jeff Law at the University of Utah (HPPA mainly), |
| Michael Meissner of the Open Software Foundation (i386 mainly), and Ken |
| Raeburn of Cygnus Support (sparc, and some initial 64-bit support). |
| |
| Linas Vepstas added GAS support for the ESA/390 "IBM 370" |
| architecture. |
| |
| Richard Henderson rewrote the Alpha assembler. Klaus Kaempf wrote |
| GAS and BFD support for openVMS/Alpha. |
| |
| Timothy Wall, Michael Hayes, and Greg Smart contributed to the |
| various tic* flavors. |
| |
| David Heine, Sterling Augustine, Bob Wilson and John Ruttenberg from |
| Tensilica, Inc. added support for Xtensa processors. |
| |
| Several engineers at Cygnus Support have also provided many small |
| bug fixes and configuration enhancements. |
| |
| Many others have contributed large or small bugfixes and |
| enhancements. If you have contributed significant work and are not |
| mentioned on this list, and want to be, let us know. Some of the |
| history has been lost; we are not intentionally leaving anyone out. |

| Version 1.1, March 2000 |
| Copyright (C) 2000, Free Software Foundation, Inc. |
| 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA |
| |
| Everyone is permitted to copy and distribute verbatim copies |
| of this license document, but changing it is not allowed. |
| |
| |
| 0. PREAMBLE |
| |
| The purpose of this License is to make a manual, textbook, or other |
| written document "free" in the sense of freedom: to assure everyone |
| the effective freedom to copy and redistribute it, with or without |
| modifying it, either commercially or noncommercially. Secondarily, |
| this License preserves for the author and publisher a way to get |
| credit for their work, while not being considered responsible for |
| modifications made by others. |
| |
| This License is a kind of "copyleft", which means that derivative |
| works of the document must themselves be free in the same sense. |
| It complements the GNU General Public License, which is a copyleft |
| license designed for free software. |
| |
| We have designed this License in order to use it for manuals for |
| free software, because free software needs free documentation: a |
| free program should come with manuals providing the same freedoms |
| that the software does. But this License is not limited to |
| software manuals; it can be used for any textual work, regardless |
| of subject matter or whether it is published as a printed book. |
| We recommend this License principally for works whose purpose is |
| instruction or reference. |
| |
| |
| 1. APPLICABILITY AND DEFINITIONS |
| |
| This License applies to any manual or other work that contains a |
| notice placed by the copyright holder saying it can be distributed |
| under the terms of this License. The "Document", below, refers to |
| any such manual or work. Any member of the public is a licensee, |
| and is addressed as "you." |
| |
| A "Modified Version" of the Document means any work containing the |
| Document or a portion of it, either copied verbatim, or with |
| modifications and/or translated into another language. |
| |
| A "Secondary Section" is a named appendix or a front-matter |
| section of the Document that deals exclusively with the |
| relationship of the publishers or authors of the Document to the |
| Document's overall subject (or to related matters) and contains |
| nothing that could fall directly within that overall subject. |
| (For example, if the Document is in part a textbook of |
| mathematics, a Secondary Section may not explain any mathematics.) |
| The relationship could be a matter of historical connection with |
| the subject or with related matters, or of legal, commercial, |
| philosophical, ethical or political position regarding them. |
| |
| The "Invariant Sections" are certain Secondary Sections whose |
| titles are designated, as being those of Invariant Sections, in |
| the notice that says that the Document is released under this |
| License. |
| |
| The "Cover Texts" are certain short passages of text that are |
| listed, as Front-Cover Texts or Back-Cover Texts, in the notice |
| that says that the Document is released under this License. |
| |
| A "Transparent" copy of the Document means a machine-readable copy, |
| represented in a format whose specification is available to the |
| general public, whose contents can be viewed and edited directly |
| and straightforwardly with generic text editors or (for images |
| composed of pixels) generic paint programs or (for drawings) some |
| widely available drawing editor, and that is suitable for input to |
| text formatters or for automatic translation to a variety of |
| formats suitable for input to text formatters. A copy made in an |
| otherwise Transparent file format whose markup has been designed |
| to thwart or discourage subsequent modification by readers is not |
| Transparent. A copy that is not "Transparent" is called "Opaque." |
| |
| Examples of suitable formats for Transparent copies include plain |
| ASCII without markup, Texinfo input format, LaTeX input format, |
| SGML or XML using a publicly available DTD, and |
| standard-conforming simple HTML designed for human modification. |
| Opaque formats include PostScript, PDF, proprietary formats that |
| can be read and edited only by proprietary word processors, SGML |
| or XML for which the DTD and/or processing tools are not generally |
| available, and the machine-generated HTML produced by some word |
| processors for output purposes only. |
| |
| The "Title Page" means, for a printed book, the title page itself, |
| plus such following pages as are needed to hold, legibly, the |
| material this License requires to appear in the title page. For |
| works in formats which do not have any title page as such, "Title |
| Page" means the text near the most prominent appearance of the |
| work's title, preceding the beginning of the body of the text. |
| |
| 2. VERBATIM COPYING |
| |
| You may copy and distribute the Document in any medium, either |
| commercially or noncommercially, provided that this License, the |
| copyright notices, and the license notice saying this License |
| applies to the Document are reproduced in all copies, and that you |
| add no other conditions whatsoever to those of this License. You |
| may not use technical measures to obstruct or control the reading |
| or further copying of the copies you make or distribute. However, |
| you may accept compensation in exchange for copies. If you |
| distribute a large enough number of copies you must also follow |
| the conditions in section 3. |
| |
| You may also lend copies, under the same conditions stated above, |
| and you may publicly display copies. |
| |
| 3. COPYING IN QUANTITY |
| |
| If you publish printed copies of the Document numbering more than |
| 100, and the Document's license notice requires Cover Texts, you |
| must enclose the copies in covers that carry, clearly and legibly, |
| all these Cover Texts: Front-Cover Texts on the front cover, and |
| Back-Cover Texts on the back cover. Both covers must also clearly |
| and legibly identify you as the publisher of these copies. The |
| front cover must present the full title with all words of the |
| title equally prominent and visible. You may add other material |
| on the covers in addition. Copying with changes limited to the |
| covers, as long as they preserve the title of the Document and |
| satisfy these conditions, can be treated as verbatim copying in |
| other respects. |
| |
| If the required texts for either cover are too voluminous to fit |
| legibly, you should put the first ones listed (as many as fit |
| reasonably) on the actual cover, and continue the rest onto |
| adjacent pages. |
| |
| If you publish or distribute Opaque copies of the Document |
| numbering more than 100, you must either include a |
| machine-readable Transparent copy along with each Opaque copy, or |
| state in or with each Opaque copy a publicly-accessible |
| computer-network location containing a complete Transparent copy |
| of the Document, free of added material, which the general |
| network-using public has access to download anonymously at no |
| charge using public-standard network protocols. If you use the |
| latter option, you must take reasonably prudent steps, when you |
| begin distribution of Opaque copies in quantity, to ensure that |
| this Transparent copy will remain thus accessible at the stated |
| location until at least one year after the last time you |
| distribute an Opaque copy (directly or through your agents or |
| retailers) of that edition to the public. |
| |
| It is requested, but not required, that you contact the authors of |
| the Document well before redistributing any large number of |
| copies, to give them a chance to provide you with an updated |
| version of the Document. |
| |
| 4. MODIFICATIONS |
| |
| You may copy and distribute a Modified Version of the Document |
| under the conditions of sections 2 and 3 above, provided that you |
| release the Modified Version under precisely this License, with |
| the Modified Version filling the role of the Document, thus |
| licensing distribution and modification of the Modified Version to |
| whoever possesses a copy of it. In addition, you must do these |
| things in the Modified Version: |
| |
| A. Use in the Title Page (and on the covers, if any) a title |
| distinct from that of the Document, and from those of previous |
| versions (which should, if there were any, be listed in the |
| History section of the Document). You may use the same title |
| as a previous version if the original publisher of that version |
| gives permission. |
| B. List on the Title Page, as authors, one or more persons or |
| entities responsible for authorship of the modifications in the |
| Modified Version, together with at least five of the principal |
| authors of the Document (all of its principal authors, if it |
| has less than five). |
| C. State on the Title page the name of the publisher of the |
| Modified Version, as the publisher. |
| D. Preserve all the copyright notices of the Document. |
| E. Add an appropriate copyright notice for your modifications |
| adjacent to the other copyright notices. |
| F. Include, immediately after the copyright notices, a license |
| notice giving the public permission to use the Modified Version |
| under the terms of this License, in the form shown in the |
| Addendum below. |
| G. Preserve in that license notice the full lists of Invariant |
| Sections and required Cover Texts given in the Document's |
| license notice. |
| H. Include an unaltered copy of this License. |
| I. Preserve the section entitled "History", and its title, and add |
| to it an item stating at least the title, year, new authors, and |
| publisher of the Modified Version as given on the Title Page. |
| If there is no section entitled "History" in the Document, |
| create one stating the title, year, authors, and publisher of |
| the Document as given on its Title Page, then add an item |
| describing the Modified Version as stated in the previous |
| sentence. |
| J. Preserve the network location, if any, given in the Document for |
| public access to a Transparent copy of the Document, and |
| likewise the network locations given in the Document for |
| previous versions it was based on. These may be placed in the |
| "History" section. You may omit a network location for a work |
| that was published at least four years before the Document |
| itself, or if the original publisher of the version it refers |
| to gives permission. |
| K. In any section entitled "Acknowledgements" or "Dedications", |
| preserve the section's title, and preserve in the section all the |
| substance and tone of each of the contributor acknowledgements |
| and/or dedications given therein. |
| L. Preserve all the Invariant Sections of the Document, |
| unaltered in their text and in their titles. Section numbers |
| or the equivalent are not considered part of the section titles. |
| M. Delete any section entitled "Endorsements." Such a section |
| may not be included in the Modified Version. |
| N. Do not retitle any existing section as "Endorsements" or to |
| conflict in title with any Invariant Section. |
| |
| If the Modified Version includes new front-matter sections or |
| appendices that qualify as Secondary Sections and contain no |
| material copied from the Document, you may at your option |
| designate some or all of these sections as invariant. To do this, |
| add their titles to the list of Invariant Sections in the Modified |
| Version's license notice. These titles must be distinct from any |
| other section titles. |
| |
| You may add a section entitled "Endorsements", provided it contains |
| nothing but endorsements of your Modified Version by various |
| parties-for example, statements of peer review or that the text has |
| been approved by an organization as the authoritative definition |
| of a standard. |
| |
| You may add a passage of up to five words as a Front-Cover Text, |
| and a passage of up to 25 words as a Back-Cover Text, to the end |
| of the list of Cover Texts in the Modified Version. Only one |
| passage of Front-Cover Text and one of Back-Cover Text may be |
| added by (or through arrangements made by) any one entity. If the |
| Document already includes a cover text for the same cover, |
| previously added by you or by arrangement made by the same entity |
| you are acting on behalf of, you may not add another; but you may |
| replace the old one, on explicit permission from the previous |
| publisher that added the old one. |
| |
| The author(s) and publisher(s) of the Document do not by this |
| License give permission to use their names for publicity for or to |
| assert or imply endorsement of any Modified Version. |
| |
| 5. COMBINING DOCUMENTS |
| |
| You may combine the Document with other documents released under |
| this License, under the terms defined in section 4 above for |
| modified versions, provided that you include in the combination |
| all of the Invariant Sections of all of the original documents, |
| unmodified, and list them all as Invariant Sections of your |
| combined work in its license notice. |
| |
| The combined work need only contain one copy of this License, and |
| multiple identical Invariant Sections may be replaced with a single |
| copy. If there are multiple Invariant Sections with the same name |
| but different contents, make the title of each such section unique |
| by adding at the end of it, in parentheses, the name of the |
| original author or publisher of that section if known, or else a |
| unique number. Make the same adjustment to the section titles in |
| the list of Invariant Sections in the license notice of the |
| combined work. |
| |
| In the combination, you must combine any sections entitled |
| "History" in the various original documents, forming one section |
| entitled "History"; likewise combine any sections entitled |
| "Acknowledgements", and any sections entitled "Dedications." You |
| must delete all sections entitled "Endorsements." |
| |
| 6. COLLECTIONS OF DOCUMENTS |
| |
| You may make a collection consisting of the Document and other |
| documents released under this License, and replace the individual |
| copies of this License in the various documents with a single copy |
| that is included in the collection, provided that you follow the |
| rules of this License for verbatim copying of each of the |
| documents in all other respects. |
| |
| You may extract a single document from such a collection, and |
| distribute it individually under this License, provided you insert |
| a copy of this License into the extracted document, and follow |
| this License in all other respects regarding verbatim copying of |
| that document. |
| |
| 7. AGGREGATION WITH INDEPENDENT WORKS |
| |
| A compilation of the Document or its derivatives with other |
| separate and independent documents or works, in or on a volume of |
| a storage or distribution medium, does not as a whole count as a |
| Modified Version of the Document, provided no compilation |
| copyright is claimed for the compilation. Such a compilation is |
| called an "aggregate", and this License does not apply to the |
| other self-contained works thus compiled with the Document, on |
| account of their being thus compiled, if they are not themselves |
| derivative works of the Document. |
| |
| If the Cover Text requirement of section 3 is applicable to these |
| copies of the Document, then if the Document is less than one |
| quarter of the entire aggregate, the Document's Cover Texts may be |
| placed on covers that surround only the Document within the |
| aggregate. Otherwise they must appear on covers around the whole |
| aggregate. |
| |
| 8. TRANSLATION |
| |
| Translation is considered a kind of modification, so you may |
| distribute translations of the Document under the terms of section |
| 4. Replacing Invariant Sections with translations requires special |
| permission from their copyright holders, but you may include |
| translations of some or all Invariant Sections in addition to the |
| original versions of these Invariant Sections. You may include a |
| translation of this License provided that you also include the |
| original English version of this License. In case of a |
| disagreement between the translation and the original English |
| version of this License, the original English version will prevail. |
| |
| 9. TERMINATION |
| |
| You may not copy, modify, sublicense, or distribute the Document |
| except as expressly provided for under this License. Any other |
| attempt to copy, modify, sublicense or distribute the Document is |
| void, and will automatically terminate your rights under this |
| License. However, parties who have received copies, or rights, |
| from you under this License will not have their licenses |
| terminated so long as such parties remain in full compliance. |
| |
| 10. FUTURE REVISIONS OF THIS LICENSE |
| |
| The Free Software Foundation may publish new, revised versions of |
| the GNU Free Documentation License from time to time. Such new |
| versions will be similar in spirit to the present version, but may |
| differ in detail to address new problems or concerns. See |
| http://www.gnu.org/copyleft/. |
| |
| Each version of the License is given a distinguishing version |
| number. If the Document specifies that a particular numbered |
| version of this License "or any later version" applies to it, you |
| have the option of following the terms and conditions either of |
| that specified version or of any later version that has been |
| published (not as a draft) by the Free Software Foundation. If |
| the Document does not specify a version number of this License, |
| you may choose any version ever published (not as a draft) by the |
| Free Software Foundation. |
| |
| |
| ADDENDUM: How to use this License for your documents |
| ==================================================== |
| |
| To use this License in a document you have written, include a copy of |
| the License in the document and put the following copyright and license |
| notices just after the title page: |
| |
| Copyright (C) YEAR YOUR NAME. |
| Permission is granted to copy, distribute and/or modify this document |
| under the terms of the GNU Free Documentation License, Version 1.1 |
| or any later version published by the Free Software Foundation; |
| with the Invariant Sections being LIST THEIR TITLES, with the |
| Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. |
| A copy of the license is included in the section entitled "GNU |
| Free Documentation License." |
| |
| If you have no Invariant Sections, write "with no Invariant Sections" |
| instead of saying which ones are invariant. If you have no Front-Cover |
| Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being |
| LIST"; likewise for Back-Cover Texts. |
| |
| If your document contains nontrivial examples of program code, we |
| recommend releasing these examples in parallel under your choice of |
| free software license, such as the GNU General Public License, to |
| permit their use in free software. |
| |
