CREATIVE COMMONS PROVIDES THIS INFORMATION ON AN "AS-IS" BASIS. +CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE INFORMATION PROVIDED, AND +DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM ITS USE. +License +THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE +COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY +COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS +AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS PROHIBITED. +BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE TO BE +BOUND BY THE TERMS OF THIS LICENSE. THE LICENSOR GRANTS YOU THE RIGHTS +CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND +CONDITIONS. +1. Definitions + + a. "Collective Work" means a work, such as a periodical issue, anthology or + encyclopedia, in which the Work in its entirety in unmodified form, along + with a number of other contributions, constituting separate and + independent works in themselves, are assembled into a collective whole. A + work that constitutes a Collective Work will not be considered a + Derivative Work (as defined below) for the purposes of this License. + b. "Derivative Work" means a work based upon the Work or upon the Work and + other pre-existing works, such as a translation, musical arrangement, + dramatization, fictionalization, motion picture version, sound recording, + art reproduction, abridgment, condensation, or any other form in which the + Work may be recast, transformed, or adapted, except that a work that + constitutes a Collective Work will not be considered a Derivative Work for + the purpose of this License. For the avoidance of doubt, where the Work is + a musical composition or sound recording, the synchronization of the Work + in timed-relation with a moving image ("synching") will be considered a + Derivative Work for the purpose of this License. + c. "Licensor" means the individual or entity that offers the Work under the + terms of this License. + d. "Original Author" means the individual or entity who created the Work. + e. "Work" means the copyrightable work of authorship offered under the terms + of this License. + f. "You" means an individual or entity exercising rights under this License + who has not previously violated the terms of this License with respect to + the Work, or who has received express permission from the Licensor to + exercise rights under this License despite a previous violation. + g. "License Elements" means the following high-level license attributes as + selected by Licensor and indicated in the title of this License: + Attribution, ShareAlike. + +2. Fair Use Rights. Nothing in this license is intended to reduce, limit, or +restrict any rights arising from fair use, first sale or other limitations on +the exclusive rights of the copyright owner under copyright law or other +applicable laws. +3. License Grant. Subject to the terms and conditions of this License, Licensor +hereby grants You a worldwide, royalty-free, non-exclusive, perpetual (for the +duration of the applicable copyright) license to exercise the rights in the +Work as stated below: + + a. to reproduce the Work, to incorporate the Work into one or more Collective + Works, and to reproduce the Work as incorporated in the Collective Works; + b. to create and reproduce Derivative Works; + c. to distribute copies or phonorecords of, display publicly, perform + publicly, and perform publicly by means of a digital audio transmission + the Work including as incorporated in Collective Works; + d. to distribute copies or phonorecords of, display publicly, perform + publicly, and perform publicly by means of a digital audio transmission + Derivative Works. + e. For the avoidance of doubt, where the work is a musical composition: + + i. Performance Royalties Under Blanket Licenses. Licensor waives the + exclusive right to collect, whether individually or via a performance + rights society (e.g. ASCAP, BMI, SESAC), royalties for the public + performance or public digital performance (e.g. webcast) of the Work. + ii. Mechanical Rights and Statutory Royalties. Licensor waives the + exclusive right to collect, whether individually or via a music + rights society or designated agent (e.g. Harry Fox Agency), royalties + for any phonorecord You create from the Work ("cover version") and + distribute, subject to the compulsory license created by 17 USC + Section 115 of the US Copyright Act (or the equivalent in other + jurisdictions). + + f. Webcasting Rights and Statutory Royalties. For the avoidance of doubt, + where the Work is a sound recording, Licensor waives the exclusive right + to collect, whether individually or via a performance-rights society (e.g. + SoundExchange), royalties for the public digital performance (e.g. + webcast) of the Work, subject to the compulsory license created by 17 USC + Section 114 of the US Copyright Act (or the equivalent in other + jurisdictions). + +The above rights may be exercised in all media and formats whether now known or +hereafter devised. The above rights include the right to make such +modifications as are technically necessary to exercise the rights in other +media and formats. All rights not expressly granted by Licensor are hereby +reserved. +4. Restrictions.The license granted in Section 3 above is expressly made +subject to and limited by the following restrictions: + + a. You may distribute, publicly display, publicly perform, or publicly + digitally perform the Work only under the terms of this License, and You + must include a copy of, or the Uniform Resource Identifier for, this + License with every copy or phonorecord of the Work You distribute, + publicly display, publicly perform, or publicly digitally perform. You may + not offer or impose any terms on the Work that alter or restrict the terms + of this License or the recipients' exercise of the rights granted + hereunder. You may not sublicense the Work. You must keep intact all + notices that refer to this License and to the disclaimer of warranties. + You may not distribute, publicly display, publicly perform, or publicly + digitally perform the Work with any technological measures that control + access or use of the Work in a manner inconsistent with the terms of this + License Agreement. The above applies to the Work as incorporated in a + Collective Work, but this does not require the Collective Work apart from + the Work itself to be made subject to the terms of this License. If You + create a Collective Work, upon notice from any Licensor You must, to the + extent practicable, remove from the Collective Work any credit as required + by clause 4(c), as requested. If You create a Derivative Work, upon notice + from any Licensor You must, to the extent practicable, remove from the + Derivative Work any credit as required by clause 4(c), as requested. + b. You may distribute, publicly display, publicly perform, or publicly + digitally perform a Derivative Work only under the terms of this License, + a later version of this License with the same License Elements as this + License, or a Creative Commons iCommons license that contains the same + License Elements as this License (e.g. Attribution-ShareAlike 2.5 Japan). + You must include a copy of, or the Uniform Resource Identifier for, this + License or other license specified in the previous sentence with every + copy or phonorecord of each Derivative Work You distribute, publicly + display, publicly perform, or publicly digitally perform. You may not + offer or impose any terms on the Derivative Works that alter or restrict + the terms of this License or the recipients' exercise of the rights + granted hereunder, and You must keep intact all notices that refer to this + License and to the disclaimer of warranties. You may not distribute, + publicly display, publicly perform, or publicly digitally perform the + Derivative Work with any technological measures that control access or use + of the Work in a manner inconsistent with the terms of this License + Agreement. The above applies to the Derivative Work as incorporated in a + Collective Work, but this does not require the Collective Work apart from + the Derivative Work itself to be made subject to the terms of this + License. + c. If you distribute, publicly display, publicly perform, or publicly + digitally perform the Work or any Derivative Works or Collective Works, + You must keep intact all copyright notices for the Work and provide, + reasonable to the medium or means You are utilizing: (i) the name of the + Original Author (or pseudonym, if applicable) if supplied, and/or (ii) if + the Original Author and/or Licensor designate another party or parties + (e.g. a sponsor institute, publishing entity, journal) for attribution in + Licensor's copyright notice, terms of service or by other reasonable + means, the name of such party or parties; the title of the Work if + supplied; to the extent reasonably practicable, the Uniform Resource + Identifier, if any, that Licensor specifies to be associated with the + Work, unless such URI does not refer to the copyright notice or licensing + information for the Work; and in the case of a Derivative Work, a credit + identifying the use of the Work in the Derivative Work (e.g., "French + translation of the Work by Original Author," or "Screenplay based on + original Work by Original Author"). Such credit may be implemented in any + reasonable manner; provided, however, that in the case of a Derivative + Work or Collective Work, at a minimum such credit will appear where any + other comparable authorship credit appears and in a manner at least as + prominent as such other comparable authorship credit. + +5. Representations, Warranties and Disclaimer +UNLESS OTHERWISE AGREED TO BY THE PARTIES IN WRITING, LICENSOR OFFERS THE WORK +AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY KIND CONCERNING THE +MATERIALS, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE, INCLUDING, WITHOUT +LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY, FITNESS FOR A PARTICULAR +PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF LATENT OR OTHER DEFECTS, ACCURACY, +OR THE PRESENCE OF ABSENCE OF ERRORS, WHETHER OR NOT DISCOVERABLE. SOME +JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO SUCH +EXCLUSION MAY NOT APPLY TO YOU. +6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE LAW, IN +NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR ANY SPECIAL, +INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES ARISING OUT OF THIS +LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. +7. Termination + + a. This License and the rights granted hereunder will terminate automatically + upon any breach by You of the terms of this License. Individuals or + entities who have received Derivative Works or Collective Works from You + under this License, however, will not have their licenses terminated + provided such individuals or entities remain in full compliance with those + licenses. Sections 1, 2, 5, 6, 7, and 8 will survive any termination of + this License. + b. Subject to the above terms and conditions, the license granted here is + perpetual (for the duration of the applicable copyright in the Work). + Notwithstanding the above, Licensor reserves the right to release the Work + under different license terms or to stop distributing the Work at any + time; provided, however that any such election will not serve to withdraw + this License (or any other license that has been, or is required to be, + granted under the terms of this License), and this License will continue + in full force and effect unless terminated as stated above. + +8. Miscellaneous + + a. Each time You distribute or publicly digitally perform the Work or a + Collective Work, the Licensor offers to the recipient a license to the + Work on the same terms and conditions as the license granted to You under + this License. + b. Each time You distribute or publicly digitally perform a Derivative Work, + Licensor offers to the recipient a license to the original Work on the + same terms and conditions as the license granted to You under this + License. + c. If any provision of this License is invalid or unenforceable under + applicable law, it shall not affect the validity or enforceability of the + remainder of the terms of this License, and without further action by the + parties to this agreement, such provision shall be reformed to the minimum + extent necessary to make such provision valid and enforceable. + d. No term or provision of this License shall be deemed waived and no breach + consented to unless such waiver or consent shall be in writing and signed + by the party to be charged with such waiver or consent. + e. This License constitutes the entire agreement between the parties with + respect to the Work licensed here. There are no understandings, agreements + or representations with respect to the Work not specified here. Licensor + shall not be bound by any additional provisions that may appear in any + communication from You. This License may not be modified without the + mutual written agreement of the Licensor and You. + +Creative Commons is not a party to this License, and makes no warranty +whatsoever in connection with the Work. Creative Commons will not be liable to +You or any party on any legal theory for any damages whatsoever, including +without limitation any general, special, incidental or consequential damages +arising in connection to this license.

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program 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. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public 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. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + diff --git a/Makefile b/Makefile new file mode 100644 index 0000000..5f0ee05 --- /dev/null +++ b/Makefile @@ -0,0 +1,945 @@ +# +# Tremulous Makefile +# +# Nov '98 by Zoid <zoid@idsoftware.com> +# +# Loki Hacking by Bernd Kreimeier +# and a little more by Ryan C.

This document summarizes the differences +between the 4.1 code-generation interface and the 3.x interface described in Chap. 5 of <cite>A +Retargetable C Compiler</cite>.</p> + +<p>Previous versions of lcc supported only three sizes of integers, two sizes of floats, +and insisted that pointers fit in unsigned integers (see Sec. 5.1 of <cite>A Retargetable +C Compiler</cite>). These assumptions simplified the compiler, and were suitable for +32-bit architectures. But on 64-bit architectures, such as the DEC ALPHA, it's natural to +have four sizes of integers and perhaps three sizes of floats, and on 16-bit +architectures, 32-bit pointers don't fit in unsigned integers. Also, the 3.x constaints +limited the use of lcc's back ends for other languages, such as Java.</p> + +<p>Version 4.x removes all of these restrictions: It supports any number of sizes for +integers and floats, and the size of pointers need not be related to the size of any of +the integer types. The major changes in the code-generation interface are: + +<ul> + <li>The number of type suffixes has been reduced to 6.</li> + <li>Dag operators are composed of a generic operator, a type suffix, and a size.</li> + <li>Unsigned variants of several operators have been added.</li> + <li>Several interface functions have new signatures.</li> +</ul> + +<p>In addition, version 4.x is written in ANSI C and uses the standard I/O library and +other standard C functions.</p> + +<p>The sections below parallel the subsections of Chap. 5 of <cite>A Retargetable C +Compiler</cite> and summarize the differences between the 3.x and 4.x code-generation +interface. Unaffected subsections are omitted. Page citations refer to pages in <cite>A +Retargetable C Compiler</cite>.</p> + +<h2><a NAME="metrics">5.1 Type Metrics</a></h2> + +<p>There are now 10 metrics in an interface record:</p> + +<pre>Metrics charmetric; +Metrics shortmetric; +Metrics intmetric; +Metrics longmetric; +Metrics longlongmetric; +Metrics floatmetric; +Metrics doublemetric; +Metrics longdoublemetric; +Metrics ptrmetric; +Metrics structmetric;</pre> + +<p>Each of these specifies the size and alignment of the corresponding type. <code>ptrmetric</code> +describes all pointers.</p> + +<h2><a NAME="symbols">5.3 Symbols</a></h2> + +<p>The actual value of a constant is stored in the <code>u.c.v</code> field of a symbol, +which holds a <code>Value</code>:</p> + +<pre>typedef union value { + long i; + unsigned long u; + long double d; + void *p; + void (*g)(void); +} Value;</pre> + +<p>The value is stored in the appropriate field according to its type, which is given by +the symbol's <code>type</code> field.</p> + +<h2><a NAME="operators">5.5 Dag Operators</a></h2> + +<p>The <code>op</code> field a of <code>node</code> structure holds a dag operator, which +consists of a generic operator, a type suffix, and a size indicator. The type suffixes +are:</p> + +<pre>enum { + F=FLOAT, + I=INT, + U=UNSIGNED, + P=POINTER, + V=VOID, + B=STRUCT +}; + +#define sizeop(n) ((n)<<10)</pre> + +<p>Given a generic operator <code>o</code>, a type suffix <code>t</code>, and a size <code>s</code>, +a type- and size-specific operator is formed by <code>o+t+sizeop(s)</code>. For example, <code>ADD+F+sizeop(4)</code> +forms the operator <code>ADDF4</code>, which denotes the sum of two 4-byte floats. +Similarly, <code>ADD+F+sizeop(8)</code> forms <code>ADDF8</code>, which denotes 8-byte +floating addition. In the 3.x code-generation interface, <code>ADDF</code> and <code>ADDD</code> +denoted these operations. There was no size indicator in the 3.x operators because the +type suffix supplied both a type and a size.</p> + +<p>Table 5.1 lists each generic operator, its valid type suffixes, and the number of <code>kids</code> +and <code>syms</code> that it uses; multiple values for <code>kids</code> indicate +type-specific variants. The notations in the <strong>syms</strong> column give the number +of <code>syms</code> values and a one-letter code that suggests their uses: 1V indicates +that <code>syms[0]</code> points to a symbol for a variable, 1C indicates that <code>syms[0]</code> +is a constant, and 1L indicates that <code>syms[0]</code> is a label. For 1S, <code>syms[0]</code> +is a constant whose value is a size in bytes; 2S adds <code>syms[1]</code>, which is a +constant whose value is an alignment. For most operators, the type suffix and size +indicator denote the type and size of operation to perform and the type and size of the +result.</p> + +<table WIDTH="100%" BORDER="0" CELLPADDING="0"

operators that +back ends must implement. Letters denote the size of float (f), double (d), long double +(x), character (c), short integer (s), integer (i), long integer (l), "long +long" integer (h) , and pointer (p). These sizes are separated into sets for each +type suffix, except that a single set is used for both I and U when the set for I is +identical to the set for U.</p> + +<p>The actual values for the size indicators, fdxcsilhp, depend on the target. A +specification like <code>ADDF</code>f denotes the operator <code>ADD+F+sizeop(</code>f<code>)</code>, +where "f" is replaced by a target-dependent value, e.g., <code>ADDF4</code> and <code>ADDF8</code>. +For example, back ends must implement the following <code>CVI</code> and <code>MUL</code> +operators.</p> + +<blockquote> + <p><code>CVIF</code>f <code>CVIF</code>d <code>CVIF</code>x<br> + <code>CVII</code>c <code>CVII</code>s <code>CVII</code>i <code>CVII</code>l <code>CVII</code>h<br> + <code>CVIU</code>c <code>CVIU</code>s <code>CVIU</code>i <code>CVIU</code>l <code>CVIU</code>h + <code>CVIU</code>p<br> + <br> + <code>MULF</code>f <code>MULF</code>d <code>MULF</code>x<br> + <code>MULI</code>i <code>MULI</code>l <code>MULI</code>h<br> + <code>MULU</code>i <code>MULU</code>l <code>MULU</code>h</p> +</blockquote> + +<p>On most platforms, there are fewer than three sizes of floats and six sizes of +integers, and pointers are usually the same size as one of the integers. And lcc doesn't +support the "long long" type, so h is not currently used. So the set of +platform-specific operators is usually smaller than the list above suggests. For example, +the X86, SPARC, and MIPS back ends implement the following <code>CVI</code> and <code>MUL</code> +operators.</p> + +<blockquote> + <p><code>CVIF</code>4 <code>CVIF</code>8<br> + <code>CVII</code>1 <code>CVII</code>2 <code>CVII</code>4<br> + <code>CVIU</code>1 <code>CVIU</code>2 <code>CVIU</code>4 <br> + <br> + <code>MULF</code>4 <code>MULF</code>8<br> + <code>MULI</code>4<br> + <code>MULU</code>4</p> +</blockquote> + +<p>The set of operators is thus target-dependent; for example, <code>ADDI8</code> appears +only if the target supports an 8-byte integer type. <a +HREF="ftp://ftp.cs.princeton.edu/pub/packages/lcc/contrib/ops.c"><code>ops.c</code></a> is +a program that, given a set of sizes, prints the required operators and their values, +e.g.,</p> + +<blockquote> + <pre>% <em>ops c=1 s=2 i=4 l=4 h=4 f=4 d=8 x=8 p=4</em> +... + CVIF4=4225 CVIF8=8321 + CVII1=1157 CVII2=2181 CVII4=4229 + CVIU1=1158 CVIU2=2182 CVIU4=4230 +... + MULF4=4561 MULF8=8657 + MULI4=4565 + MULU4=4566 +... +131 operators</pre> +</blockquote> + +<p>The type suffix for a conversion operator denotes the type of the result and the size +indicator gives the size of the result.

On multi-platform systems supported by +a central file server, it's common to store the build directory in a location specific to +the platform and to the version of lcc, and to point a symbolic link to this location. For +example,</p> + +<blockquote> + <pre>% ln -s /usr/local/lib/lcc-4.1/sparc-solaris /usr/local/lib/lcc</pre> +</blockquote> + +<p>points <code>/usr/local/lib/lcc</code> to a build directory for lcc version 4.1 on the +SPARC under Solaris. Links into <code>/usr/local/lib</code> are created for the programs <code>lcc</code> +and <code>bprint</code>. Thus, a new distribution can be installed by building it in its +own build directory and changing one symbolic link to point to that directory. If these +conventions or their equivalents are followed, the host-specific parts of the driver +program, <code>lcc</code>, can be used unmodified.</p> + +<p>Installation on a UNIX system involves the following steps. Below, the build directory +is referred to as <code>BUILDDIR</code>. + +<ol> + <li>Create the build directory, using a version- and platform-specific naming convention as + suggested above, and record the name of this directory in the <code>BUILDDIR</code> + environment variable:<blockquote> + <pre>% setenv BUILDDIR /usr/local/lib/lcc-4.1/sparc-solaris +% mkdir -p $BUILDDIR</pre> + </blockquote> + <p>Here and below, commands assume the C shell. Also, you'll need a version of <code>mkdir</code> + that supports the <code>-p</code> option, which creates intermediate directories as + necessary.</p> + </li> + <li>Copy the man pages to the repository for local man pages, e.g.,<blockquote> + <pre>% cp doc/*.1 /usr/local/man/man1</pre> + </blockquote> + <p>Some users copy the man pages to the build directory and create the appropriate + symbolic links, e.g., </p> + <blockquote> + <pre>% cp doc/*.1 $BUILDDIR +% ln -s $BUILDDIR/*.1 /usr/local/man/man1</pre> + </blockquote> + </li> + <li>Platform-specific include files are in directories named <code>include/</code><em>target</em><code>/</code><em>os</em>. + Create the include directory in the build directory, and copy the include hierarchy for + your platform to this directory, e.g.,<blockquote> + <pre>% mkdir $BUILDDIR/include +% cp -p -R include/sparc/solaris/* $BUILDDIR/include</pre> + </blockquote> + <p>Again, some users create a symbolic link to the appropriate directory in the + distribution instead of copying the include files. For example, at Princeton, the + distributions are stored under <code>/proj/pkg/lcc</code>, so the included files are + "installed" by creating one symbolic link: </p> + <blockquote> + <pre>% ln -s /proj/pkg/lcc/4.1/include/sparc/solaris $BUILDDIR/include</pre> + </blockquote> + <p>If you're installing lcc on Linux, you <em>must</em> also plant a symbolic link named <code>gcc</code> + to gcc's library directory, because lcc uses gcc's C preprocessor and most of gcc's header + files:</p> + <blockquote> + <pre>% ln -s /usr/lib/gcc-lib/i486-linux/2.7.2.2 $BUILDDIR/gcc</pre> + </blockquote> + <p>The library directory shown above may be different on your Linux machine; to determine + the correct directory, browse <code>/usr/lib/gcc-lib</code>, or execute</p> + <blockquote> + <pre>% cc -v tst/8q.c</pre> + </blockquote> + <p>and examine the diagnostic output. Make sure that <code>$BUILDDIR/gcc/cpp</code> and <code>$BUILDDIR/gcc/include</code> + point to, respectively, gcc's C preprocessor and header files. On Linux, lcc looks for + include files in <code>$BUILDDIR/include</code>, <code>$BUILDDIR/gcc/include</code>, and <code>/usr/include</code>, + in that order; see <a HREF="#driver"><em>Building the Driver</em></a> and <a + href="../etc/linux.c"><code>etc/linux.c</code></a> for details.</p> + </li> + <li>The <a HREF="../makefile"><code>makefile</code></a> includes the file named by the <code>CUSTOM</code> + macro; the default is <code>custom.mk</code>, and an empty <code>custom.mk</code> is + included in the distribution. If desired, prepare a site-specification customization file + and define <code>CUSTOM</code> to the path of that file when invoking make in steps 5 and + 6, e.g.,<blockquote> + <pre>make CUSTOM=/users/drh/solaris.mk</pre> + </blockquote> + <p>You can, for example, use customization files to record site-specific values for macros + instead of using environment variables, and to record targets for the steps in this list.</p> + </li> + <li>Build the host-specific driver, creating a custom host-specific part, if necessary.

The advantange of creating the links for <code>lcc</code> + and <code>bprint</code> as shown is that, once established, they point indirectly to + whatever <code>/usr/local/lib/lcc</code> points to; installing a new version of lcc, say, + 4.2, can be done by changing <code>/usr/local/lib/lcc</code> to point to the 4.2 build + directory.</p> + </li> +</ol> + +<h2><a NAME="driver">Building the Driver</a></h2> + +<p>The preprocessor, compiler, assembler, and loader are invoked by a driver program, <code>lcc</code>, +which is similar to <code>cc</code> on most systems. It's described in the man page <code>doc/lcc.1</code>. +The driver is built by combining the host-independent part, <a href="../etc/lcc.c"><code>etc/lcc.c</code></a>, +with a small host-specific part. Distributed host-specific parts are named <code>etc/</code><em>os</em><code>.c</code>, +where <em>os</em> is the name of the operating system for the host on which <code>lcc</code> +is being installed. If you're following the installations conventions described above, you +can probably use one of the host-specific parts unmodified; otherwise, pick one that is +closely related to your platform, copy it to <em>whatever</em><code>.c</code>, and edit it +as described below.

they are preprocessed, compiled, and +each object program is left on the file +whose name is that of the source with `.o' (UNIX) or `.obj' (Windows) +substituted for the extension. +Arguments whose names end with `.i' are treated similarly, +except they are not preprocessed. +In the same way, +arguments ending with `.s' (plus `.S', `.asm', and `.ASM', under Windows) +are taken to be assembly source programs +and are assembled, producing an object file. +If there are no arguments, +.I lcc +summarizes its options on the standard error. +.PP +.I lcc +deletes an object file if and only if exactly one +source file is mentioned and no other file +(source, object, library) or +.B \-l +option is mentioned. +.PP +If the environment variable +.B LCCINPUTS +is set, +.I lcc +assumes it gives a semicolon- or colon-separated list of directories in which to +look for source and object files whose names do not begin with `/'. +These directories are also added to the list of directories +searched for libraries. +If +.B LCCINPUTS +is defined, it must contain `.' in order for the current directory +to be searched for input files. +.PP +.I lcc +uses ANSI standard header files (see `FILES' below). +Include files not found in the ANSI header files +are taken from the normal default include areas, +which usually includes +.BR /usr/include . +Under Windows, if the environment variable +.B include +is defined, it gives a semicolon-separated list of directories in which to search for +header files. +.PP +.I lcc +interprets the following options; unrecognized options are +taken as loader options (see +.IR ld (1)) +unless +.BR \-c , +.BR \-S , +or +.B \-E +precedes them. +Except for +.BR \-l , +all options are processed before any of the files +and apply to all of the files. +Applicable options are passed to each compilation phase in the order given. +.TP +.B \-c +Suppress the loading phase of the compilation, and force +an object file to be produced even if only one program is compiled. +.TP +.B \-g +Produce additional symbol table information for the local debuggers. +.I lcc +warns when +.B \-g +is unsupported. +.TP +.BI \-Wf\-g n , x +Set the debugging level to +.I n +and emit source code as comments into the generated assembly code; +.I x +must be the assembly language comment character. +If +.I n +is omitted, it defaults to 1, which is similar to +.BR \-g . +Omitting +.BI , x +just sets the debugging level to +.IR n . +.TP +.B \-w +Suppress warning diagnostics, such as those +announcing unreferenced statics, locals, and parameters. +The line +.I +#pragma ref id +simulates a reference to the variable +.IR id . +.TP +.BI \-d n +Generate jump tables for switches whose density is at least +.IR n , +a floating point constant between zero and one. +The default is 0.5. +.TP +.B \-A +Warns about +declarations and casts of function types without prototypes, +assignments between pointers to ints and pointers to enums, and +conversions from pointers to smaller integral types. +A second +.B \-A +warns about +unrecognized control lines, +nonANSI language extensions and source characters in literals, +unreferenced variables and static functions, +declaring arrays of incomplete types, +and exceeding +.I some +ANSI environmental limits, like more than 257 cases in switches. +It also arranges for duplicate global definitions in separately compiled +files to cause loader errors. +.TP +.B \-P +Writes declarations for all defined globals on standard error. +Function declarations include prototypes; +editing this output can simplify conversion to ANSI C. +This output may not correspond to the input when +there are several typedefs for the same type. +.TP +.B \-n +Arrange for the compiler to produce code +that tests for dereferencing zero pointers. +The code reports the offending file and line number and calls +.IR abort (3). +.TP +.B \-O +is ignored. +.TP +.B \-S +Compile the named C programs, and leave the +assembler-language output on corresponding files suffixed `.s' or `.asm'. +.TP +.B \-E +Run only the preprocessor on the named C programs +and unsuffixed file arguments, +and send the result to the standard output. +.TP +.BI \-o " output" +Name the output file +.IR output . +If +.B \-c +or +.B \-S +is specified and there is exactly one source file, +this option names the object or assembly file, respectively. +Otherwise, this option names the final executable +file generated by the loader, and `a.out' (UNIX) or `a.exe' (Windows) is left undisturbed. +.I lcc +warns if +.B \-o +and +.B \-c +or +.B \-S +are given with more than one source file and ignores the +.B \-o +option. +.TP +.BI \-D name=def +Define the +.I name +to the preprocessor, as if by `#define'. +If +.I =def +is omitted, the name is defined as "1". +.TP +.BI \-U name +Remove any initial definition of +.IR name . +.TP +.BI \-I dir +`#include' files +whose names do not begin with `/' are always +sought first in the directory of the +.I file +arguments, then in directories named in +.B \-I +options, then in directories on a standard list. +.TP +.B \-N +Do not search +.I any +of the standard directories for `#include' files. +Only those directories specified by subsequent explicit +.B \-I +options will be searched, in the order given. +.TP +.BI \-B str +Use the compiler +.BI "" str rcc +instead of the default version. +Note that +.I str +often requires a trailing slash. +On Sparcs only, +.B \-Bstatic +and +.BI \-Bdynamic +are passed to the loader;

+remaining registers are assigned to automatic locals if they +are `referenced' at least 3 times. +Each top-level occurrence of an identifier +counts as 1 reference. Occurrences in a loop, +either of the then/else arms of an if statement, or a case +in a switch statement each count, respectively, as 10, 1/2, or 1/10 references. +These values are adjusted accordingly for nested control structures. +.B \-Wf\-a +causes +.I lcc +to read a +.B prof.out +file from a previous execution and to use the data therein +to compute reference counts (see +.BR \-b ). +.PP +.I lcc +is a cross compiler; +.BI \-Wf\-target= target/os +causes +.I lcc +to generate code for +.I target +running the operating system denoted by +.IR os . +The supported +.I target/os +combinations may include +.PP +.RS +.ta \w'sparc/solarisxx'u +.nf +alpha/osf ALPHA, OSF 3.2 +mips/irix big-endian MIPS, IRIX 5.2 +mips/ultrix little-endian MIPS, ULTRIX 4.3 +sparc/solaris SPARC, Solaris 2.3 +x86/win32 x86, Windows NT 4.0/Windows 95/98 +x86/linux x86, Linux +symbolic text rendition of the generated code +null no output +.fi +.RE +.PP +For +.BR \-Wf\-target=symbolic , +the option +.B \-Wf-html +causes the text rendition to be emitted as HTML. +.B +.SH LIMITATIONS +.PP +.I lcc +accepts the C programming language +as described in the ANSI standard. +If +.I lcc +is used with the GNU C preprocessor, the +.B \-Wp\-trigraphs +option is required to enable trigraph sequences. +.PP +Plain int bit fields are signed. +Bit fields are aligned like unsigned integers but are otherwise laid out +as by most standard C compilers. +Some compilers, such as the GNU C compiler, +may choose other, incompatible layouts. +.PP +Likewise, calling conventions are intended to be compatible with +the host C compiler, +except possibly for passing and returning structures. +Specifically, +.I lcc +passes and returns structures like host ANSI C compilers +on most targets, but some older host C compilers use different conventions. +Consequently, calls to/from such functions compiled with +older C compilers may not work. +Calling a function that returns +a structure without declaring it as such violates +the ANSI standard and may cause a fault. +.SH FILES +.PP +The file names listed below are +.IR typical , +but vary among installations; installation-dependent variants +can be displayed by running +.I lcc +with the +.B \-v +option. +.PP +.RS +.ta \w'$LCCDIR/liblcc.{a,lib}XX'u +.nf +file.{c,C} input file +file.{s,asm} assembly-language file +file.{o,obj} object file +a.{out,exe} loaded output +/tmp/lcc* temporary files +$LCCDIR/cpp preprocessor +$LCCDIR/rcc compiler +$LCCDIR/liblcc.{a,lib} \fIlcc\fP-specific library +/lib/crt0.o runtime startup (UNIX) +/lib/[gm]crt0.o startups for profiling (UNIX) +/lib/libc.a standard library (UNIX) +$LCCDIR/include ANSI standard headers +/usr/local/include local headers +/usr/include traditional headers +prof.out file produced for \fIbprint\fR(1) +mon.out file produced for \fIprof\fR(1) +gmon.out file produced for \fIgprof\fR(1) +.fi +.RE +.PP +.I lcc +predefines the macro +.B __LCC__ +on all systems. +It may also predefine some installation-dependent symbols; option +.B \-v +exposes them. +.SH "SEE ALSO" +.PP +C.

there may be several such segments. +All are concatenated and copied verbatim into the head of the output. +Text after the second +`\f(CW%%\fP', +if any, is also copied verbatim into the output, at the end. +.PP +Specifications consist of declarations, a +`\f(CW%%\fP' +separator, and rules. +Input is line-oriented; each declaration and rule must appear on a separate line, +and declarations must begin in column 1. +Declarations declare terminals \(em the operators in subject +trees \(em and associate a unique, positive external symbol +number with each one. +Nonterminals are declared by their presence +on the left side of rules. The +\f(CW%start\fP +declaration optionally declares a nonterminal as the start symbol. +In the grammar above, +\f(CWterm\fP +and +\f(CWnonterm\fP +denote identifiers that are terminals and nonterminals. +.PP +Rules define tree patterns in a fully parenthesized prefix +form. Every nonterminal denotes a tree. +Each operator has a fixed +arity, which is inferred from the rules in which it is used. +A chain rule is a rule whose pattern is another nonterminal. +If no start symbol is declared, the nonterminal defined by the first rule is used. +.PP +Each rule ends with an expression that computes the cost of matching +that rule; omitted costs +default to zero. Costs of chain rules must be constants. +.PP +The configuration section configures the output +for the trees being parsed and the client's environment. +As shown, this section must define +\f(CWNODEPTR_TYPE\fP +to be a visible typedef symbol for a pointer to a +node in the subject tree. +The labeller invokes +\f(CWOP_LABEL(p)\fP, +\f(CWLEFT\_CHILD(p)\fP, and +\f(CWRIGHT\_CHILD(p)\fP +to read the operator and children from the node pointed to by \f(CWp\fP. +If the configuration section defines these operations as macros, they are implemented in-line; +otherwise, they must be implemented as functions. +.PP +The matcher +computes and stores a single integral state in each node of the subject tree. +The configuration section must define a macro +\f(CWSTATE_LABEL(p)\fP +to access the state field of the node pointed to +by \f(CWp\fP. It must be large enough to hold a pointer, and +a macro is required because it is used as an lvalue. +.PP +.SH OPTIONS +.TP +.BI \-p \ prefix +.br +.ns +.TP +.BI \-p prefix +Use +.I prefix +as the disambiquating prefix for visible names and fields. +The default is `\f(CW_\fP'. +.TP +.B \-T +Arrange for +.sp +.nf +.ft CW + void _trace(NODEPTR_TYPE p, int eruleno, + int cost, int bestcost); +.sp +.fi +.ft R +to be called at each successful match. +\f(CWp\fP +identifies the node and +\f(CWeruleno\fP +identifies the matching rule; the rules are numbered +beginning at 1 in the order they appear in the input. +\f(CWcost\fP +is the cost of the match and +\f(CWbestcost\fP +is the cost of the best previous match.
