If you use (or have used) the GNU assembler on one architecture, you should find a fairly similar environment when you use it on another architecture. Each version has much in common with the others, including object file formats, most assembler directives (often called -\c -.I pseudo-ops)\c -\& and assembler syntax. - -For information on the syntax and pseudo-ops used by GNU \c -.B as\c -\&, see `\|\c -.B as\c -\|' entry in \c -.B info \c -(or the manual \c -.I -.I -Using as: The GNU Assembler\c -\&). - -\c -.B as\c -\& is primarily intended to assemble the output of the GNU C -compiler \c -.B gcc\c -\& for use by the linker \c -.B ld\c -\&. Nevertheless, -we've tried to make \c -.B as\c -\& assemble correctly everything that the native -assembler would. -This doesn't mean \c -.B as\c -\& always uses the same syntax as another +\fIpseudo-ops\fR) and assembler syntax. +.PP +\f(CWas\fR is primarily intended to assemble the output of the +GNU C compiler \f(CW\fR for use by the linker +\f(CW\fR. Nevertheless, we've tried to make \f(CWas\fR +assemble correctly everything that other assemblers for the same +machine would assemble. +Any exceptions are documented explicitly. +This doesn't mean \f(CWas\fR always uses the same syntax as another assembler for the same architecture; for example, we know of several incompatible versions of 680x0 assembly language syntax. - -Each time you run \c -.B as\c -\& it assembles exactly one source +.PP +Each time you run \f(CWas\fR it assembles exactly one source program. The source program is made up of one or more files. (The standard input is also a file.) - -If \c -.B as\c -\& is given no file names it attempts to read one input file -from the \c -.B as\c -\& standard input, which is normally your terminal. You -may have to type \c -.B ctl-D\c -\& to tell \c -.B as\c -\& there is no more program -to assemble. Use `\|\c -.B \-\^\-\c -\|' if you need to explicitly name the standard input file +.PP +You give \f(CWas\fR a command line that has zero or more input file +names. The input files are read (from left file name to right). A +command line argument (in any position) that has no special meaning +is taken to be an input file name. +.PP +If you give \f(CWas\fR no file names it attempts to read one input file +from the \f(CWas\fR standard input, which is normally your terminal. You +may have to type \fBctl-D\fR to tell \f(CWas\fR there is no more program +to assemble. +.PP +Use \fB--\fR if you need to explicitly name the standard input file in your command line. - -.B as\c -\& may write warnings and error messages to the standard error -file (usually your terminal).

This should not happen when a compiler +runs \f(CWas\fR automatically. Warnings report an assumption made so +that \f(CWas\fR could keep assembling a flawed program; errors report a grave problem that stops the assembly. - -.SH OPTIONS -.TP -.BR \-a -Turn on assembly listings.

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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 4. MODIFICATIONS -\" .PP -\" 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: -\" .PP -\" 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. -\" .PP -\" 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). -\" .PP -\" C. State on the Title page the name of the publisher of the -\" Modified Version, as the publisher. -\" .PP -\" D. Preserve all the copyright notices of the Document. -\" .PP -\" E. Add an appropriate copyright notice for your modifications -\" adjacent to the other copyright notices. -\" .PP -\" 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. -\" Preserve in that license notice the full lists of Invariant Sections -\" and required Cover Texts given in the Document's license notice. -\" .PP -\" H. Include an unaltered copy of this License. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" M. Delete any section entitled "Endorsements". Such a section -\" may not be included in the Modified Version. -\" .PP -\" N. Do not retitle any existing section as "Endorsements" -\" or to conflict in title with any Invariant Section. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP - -\" 5. COMBINING DOCUMENTS -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP -\" 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." -\" .PP - -\" 6. COLLECTIONS OF DOCUMENTS -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP - -\" 7. AGGREGATION WITH INDEPENDENT WORKS -\" .PP -\" 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. -\" .PP -\" 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. -\" .PP - -\" 8. TRANSLATION -\" .PP -\" 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. -\" .PP - -\" 9. TERMINATION -\" .PP -\" 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. -\" .PP - -\" 10. FUTURE REVISIONS OF THIS LICENSE -\" .PP -\" 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/. -\" .PP -\" 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. -\" .PP - -\" ADDENDUM: How to use this License for your documents -\" .PP -\" 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: -\" .PP -\" 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.
