- GNU LESSER GENERAL PUBLIC LICENSE
- Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 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.
-
-[This is the first released version of the Lesser GPL. It also counts
- as the successor of the GNU Library Public License, version 2, hence
- the version number 2.1.]
-
- Preamble
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-Licenses are intended to guarantee your freedom to share and change
-free software--to make sure the software is free for all its users.
-
- This license, the Lesser General Public License, applies to some
-specially designated software packages--typically libraries--of the
-Free Software Foundation and other authors who decide to use it. You
-can use it too, but we suggest you first think carefully about whether
-this license or the ordinary General Public License is the better
-strategy to use in any particular case, based on the explanations below.
-
- When we speak of free software, we are referring to freedom of use,
-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 and use pieces of
-it in new free programs; and that you are informed that you can do
-these things.
-
- To protect your rights, we need to make restrictions that forbid
-distributors to deny you these rights or to ask you to surrender these
-rights. These restrictions translate to certain responsibilities for
-you if you distribute copies of the library or if you modify it.
-
- For example, if you distribute copies of the library, whether gratis
-or for a fee, you must give the recipients all the rights that we gave
-you. You must make sure that they, too, receive or can get the source
-code. If you link other code with the library, you must provide
-complete object files to the recipients, so that they can relink them
-with the library after making changes to the library and recompiling
-it. And you must show them these terms so they know their rights.
-
- We protect your rights with a two-step method: (1) we copyright the
-library, and (2) we offer you this license, which gives you legal
-permission to copy, distribute and/or modify the library.
-
- To protect each distributor, we want to make it very clear that
-there is no warranty for the free library. Also, if the library is
-modified by someone else and passed on, the recipients should know
-that what they have is not the original version, so that the original
-author's reputation will not be affected by problems that might be
-introduced by others.
-
- Finally, software patents pose a constant threat to the existence of
-any free program. We wish to make sure that a company cannot
-effectively restrict the users of a free program by obtaining a
-restrictive license from a patent holder. Therefore, we insist that
-any patent license obtained for a version of the library must be
-consistent with the full freedom of use specified in this license.
-
- Most GNU software, including some libraries, is covered by the
-ordinary GNU General Public License. This license, the GNU Lesser
-General Public License, applies to certain designated libraries, and
-is quite different from the ordinary General Public License. We use
-this license for certain libraries in order to permit linking those
-libraries into non-free programs.
-
- When a program is linked with a library, whether statically or using
-a shared library, the combination of the two is legally speaking a
-combined work, a derivative of the original library. The ordinary
-General Public License therefore permits such linking only if the
-entire combination fits its criteria of freedom. The Lesser General
-Public License permits more lax criteria for linking other code with
-the library.
-
- We call this license the "Lesser" General Public License because it
-does Less to protect the user's freedom than the ordinary General
-Public License. It also provides other free software developers Less
-of an advantage over competing non-free programs. These disadvantages
-are the reason we use the ordinary General Public License for many
-libraries. However, the Lesser license provides advantages in certain
-special circumstances.
-
- For example, on rare occasions, there may be a special need to
-encourage the widest possible use of a certain library, so that it becomes
-a de-facto standard. To achieve this, non-free programs must be
-allowed to use the library. A more frequent case is that a free
-library does the same job as widely used non-free libraries. In this
-case, there is little to gain by limiting the free library to free
-software only, so we use the Lesser General Public License.
-
- In other cases, permission to use a particular library in non-free
-programs enables a greater number of people to use a large body of
-free software. For example, permission to use the GNU C Library in
-non-free programs enables many more people to use the whole GNU
-operating system, as well as its variant, the GNU/Linux operating
-system.
-
- Although the Lesser General Public License is Less protective of the
-users' freedom, it does ensure that the user of a program that is
-linked with the Library has the freedom and the wherewithal to run
-that program using a modified version of the Library.
-
- The precise terms and conditions for copying, distribution and
-modification follow. Pay close attention to the difference between a
-"work based on the library" and a "work that uses the library". The
-former contains code derived from the library, whereas the latter must
-be combined with the library in order to run.
-
- GNU LESSER GENERAL PUBLIC LICENSE
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
- 0. This License Agreement applies to any software library or other
-program which contains a notice placed by the copyright holder or
-other authorized party saying it may be distributed under the terms of
-this Lesser General Public License (also called "this License").
-Each licensee is addressed as "you".
-
- A "library" means a collection of software functions and/or data
-prepared so as to be conveniently linked with application programs
-(which use some of those functions and data) to form executables.
-
- The "Library", below, refers to any such software library or work
-which has been distributed under these terms. A "work based on the
-Library" means either the Library or any derivative work under
-copyright law: that is to say, a work containing the Library or a
-portion of it, either verbatim or with modifications and/or translated
-straightforwardly into another language. (Hereinafter, translation is
-included without limitation in the term "modification".)
-
- "Source code" for a work means the preferred form of the work for
-making modifications to it. For a library, 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 library.
-
- Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running a program using the Library is not restricted, and output from
-such a program is covered only if its contents constitute a work based
-on the Library (independent of the use of the Library in a tool for
-writing it). Whether that is true depends on what the Library does
-and what the program that uses the Library does.
-
- 1. You may copy and distribute verbatim copies of the Library's
-complete 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 distribute a copy of this License along with the
-Library.
-
- 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 Library or any portion
-of it, thus forming a work based on the Library, 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) The modified work must itself be a software library.
-
- b) You must cause the files modified to carry prominent notices
- stating that you changed the files and the date of any change.
-
- c) You must cause the whole of the work to be licensed at no
- charge to all third parties under the terms of this License.
-
- d) If a facility in the modified Library refers to a function or a
- table of data to be supplied by an application program that uses
- the facility, other than as an argument passed when the facility
- is invoked, then you must make a good faith effort to ensure that,
- in the event an application does not supply such function or
- table, the facility still operates, and performs whatever part of
- its purpose remains meaningful.
-
- (For example, a function in a library to compute square roots has
- a purpose that is entirely well-defined independent of the
- application. Therefore, Subsection 2d requires that any
- application-supplied function or table used by this function must
- be optional: if the application does not supply it, the square
- root function must still compute square roots.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Library,
-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 Library, 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 Library.
-
-In addition, mere aggregation of another work not based on the Library
-with the Library (or with a work based on the Library) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
- 3. You may opt to apply the terms of the ordinary GNU General Public
-License instead of this License to a given copy of the Library. To do
-this, you must alter all the notices that refer to this License, so
-that they refer to the ordinary GNU General Public License, version 2,
-instead of to this License. (If a newer version than version 2 of the
-ordinary GNU General Public License has appeared, then you can specify
-that version instead if you wish.) Do not make any other change in
-these notices.
-
- Once this change is made in a given copy, it is irreversible for
-that copy, so the ordinary GNU General Public License applies to all
-subsequent copies and derivative works made from that copy.
-
- This option is useful when you wish to copy part of the code of
-the Library into a program that is not a library.
-
- 4. You may copy and distribute the Library (or a portion or
-derivative of it, under Section 2) in object code or executable form
-under the terms of Sections 1 and 2 above provided that you 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.
-
- If distribution of 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 satisfies the requirement to
-distribute the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
- 5. A program that contains no derivative of any portion of the
-Library, but is designed to work with the Library by being compiled or
-linked with it, is called a "work that uses the Library". Such a
-work, in isolation, is not a derivative work of the Library, and
-therefore falls outside the scope of this License.
-
- However, linking a "work that uses the Library" with the Library
-creates an executable that is a derivative of the Library (because it
-contains portions of the Library), rather than a "work that uses the
-library". The executable is therefore covered by this License.
-Section 6 states terms for distribution of such executables.
-
- When a "work that uses the Library" uses material from a header file
-that is part of the Library, the object code for the work may be a
-derivative work of the Library even though the source code is not.
-Whether this is true is especially significant if the work can be
-linked without the Library, or if the work is itself a library. The
-threshold for this to be true is not precisely defined by law.
-
- If such an object file uses only numerical parameters, data
-structure layouts and accessors, and small macros and small inline
-functions (ten lines or less in length), then the use of the object
-file is unrestricted, regardless of whether it is legally a derivative
-work. (Executables containing this object code plus portions of the
-Library will still fall under Section 6.)
-
- Otherwise, if the work is a derivative of the Library, you may
-distribute the object code for the work under the terms of Section 6.
-Any executables containing that work also fall under Section 6,
-whether or not they are linked directly with the Library itself.
-
- 6. As an exception to the Sections above, you may also combine or
-link a "work that uses the Library" with the Library to produce a
-work containing portions of the Library, and distribute that work
-under terms of your choice, provided that the terms permit
-modification of the work for the customer's own use and reverse
-engineering for debugging such modifications.
-
- You must give prominent notice with each copy of the work that the
-Library is used in it and that the Library and its use are covered by
-this License. You must supply a copy of this License. If the work
-during execution displays copyright notices, you must include the
-copyright notice for the Library among them, as well as a reference
-directing the user to the copy of this License. Also, you must do one
-of these things:
-
- a) Accompany the work with the complete corresponding
- machine-readable source code for the Library including whatever
- changes were used in the work (which must be distributed under
- Sections 1 and 2 above); and, if the work is an executable linked
- with the Library, with the complete machine-readable "work that
- uses the Library", as object code and/or source code, so that the
- user can modify the Library and then relink to produce a modified
- executable containing the modified Library. (It is understood
- that the user who changes the contents of definitions files in the
- Library will not necessarily be able to recompile the application
- to use the modified definitions.)
-
- b) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (1) uses at run time a
- copy of the library already present on the user's computer system,
- rather than copying library functions into the executable, and (2)
- will operate properly with a modified version of the library, if
- the user installs one, as long as the modified version is
- interface-compatible with the version that the work was made with.
-
- c) Accompany the work with a written offer, valid for at
- least three years, to give the same user the materials
- specified in Subsection 6a, above, for a charge no more
- than the cost of performing this distribution.
-
- d) If distribution of the work is made by offering access to copy
- from a designated place, offer equivalent access to copy the above
- specified materials from the same place.
-
- e) Verify that the user has already received a copy of these
- materials or that you have already sent this user a copy.
-
- For an executable, the required form of the "work that uses the
-Library" must include any data and utility programs needed for
-reproducing the executable from it. However, as a special exception,
-the materials to be 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.
-
- It may happen that this requirement contradicts the license
-restrictions of other proprietary libraries that do not normally
-accompany the operating system. Such a contradiction means you cannot
-use both them and the Library together in an executable that you
-distribute.
-
- 7. You may place library facilities that are a work based on the
-Library side-by-side in a single library together with other library
-facilities not covered by this License, and distribute such a combined
-library, provided that the separate distribution of the work based on
-the Library and of the other library facilities is otherwise
-permitted, and provided that you do these two things:
-
- a) Accompany the combined library with a copy of the same work
- based on the Library, uncombined with any other library
- facilities. This must be distributed under the terms of the
- Sections above.
-
- b) Give prominent notice with the combined library of the fact
- that part of it is a work based on the Library, and explaining
- where to find the accompanying uncombined form of the same work.
-
- 8. You may not copy, modify, sublicense, link with, or distribute
-the Library except as expressly provided under this License. Any
-attempt otherwise to copy, modify, sublicense, link with, or
-distribute the Library 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.
-
- 9. 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 Library or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Library (or any work based on the
-Library), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Library or works based on it.
-
- 10. Each time you redistribute the Library (or any work based on the
-Library), the recipient automatically receives a license from the
-original licensor to copy, distribute, link with or modify the Library
-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 with
-this License.
-
- 11. 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 Library at all. For example, if a patent
-license would not permit royalty-free redistribution of the Library 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 Library.
-
-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.
-
- 12. If the distribution and/or use of the Library is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Library 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.

-Tiny C Compiler - C Scripting Everywhere - The Smallest ANSI C compiler
------------------------------------------------------------------------
-
-Features:
---------
-
-- SMALL! You can compile and execute C code everywhere, for example on
- rescue disks.
-
-- FAST! tcc generates optimized x86 code. No byte code
- overhead. Compile, assemble and link about 7 times faster than 'gcc
- -O0'.
-
-- UNLIMITED! Any C dynamic library can be used directly. TCC is
- heading torward full ISOC99 compliance. TCC can of course compile
- itself.
-
-- SAFE! tcc includes an optional memory and bound checker. Bound
- checked code can be mixed freely with standard code.
-
-- Compile and execute C source directly. No linking or assembly
- necessary. Full C preprocessor included.
-
-- C script supported : just add '#!/usr/local/bin/tcc -run' at the first
- line of your C source, and execute it directly from the command
- line.
-
-Documentation:
--------------
-
-1) Installation on a i386 Linux host (for Windows read tcc-win32.txt)
-
- ./configure
- make
- make test
- make install
-
-By default, tcc is installed in /usr/local/bin.
-./configure --help shows configuration options.
-
-
-2) Introduction
-
-We assume here that you know ANSI C. Look at the example ex1.c to know
-what the programs look like.
-
-The include file <tcclib.h> can be used if you want a small basic libc
-include support (especially useful for floppy disks). Of course, you
-can also use standard headers, although they are slower to compile.
-
-You can begin your C script with '#!/usr/local/bin/tcc -run' on the first
-line and set its execute bits (chmod a+x your_script). Then, you can
-launch the C code as a shell or perl script :-) The command line
-arguments are put in 'argc' and 'argv' of the main functions, as in
-ANSI C.
-
-3) Examples
-
-ex1.c: simplest example (hello world). Can also be launched directly
-as a script: './ex1.c'.
-
-ex2.c: more complicated example: find a number with the four
-operations given a list of numbers (benchmark).
-
-ex3.c: compute fibonacci numbers (benchmark).
-
-ex4.c: more complicated: X11 program. Very complicated test in fact
-because standard headers are being used !
-
-ex5.c: 'hello world' with standard glibc headers.
-
-tcc.c: TCC can of course compile itself. Used to check the code
-generator.
-
-tcctest.c: auto test for TCC which tests many subtle possible bugs. Used
-when doing 'make test'.
-
-4) Full Documentation
-
-Please read tcc-doc.html to have all the features of TCC.
-
-Additional information is available for the Windows port in tcc-win32.txt.
-
-License:
--------
-
-TCC is distributed under the GNU Lesser General Public License (see
-COPYING file).

-TODO list:
-
-Bugs:
-
-- fix macro substitution with nested definitions (ShangHongzhang)
-- FPU st(0) is left unclean (kwisatz haderach). Incompatible with
- optimized gcc/msc code
-
-- constructors
-- cast bug (Peter Wang)
-- define incomplete type if defined several times (Peter Wang).
-- configure --cc=tcc (still one bug in libtcc1.c)
-- test binutils/gcc compile
-- tci patch + argument.
-- see -lxxx bug (Michael Charity).
-- see transparent union pb in /urs/include/sys/socket.h
-- precise behaviour of typeof with arrays ? (__put_user macro)
- but should suffice for most cases)
-- handle '? x, y : z' in unsized variable initialization (',' is
- considered incorrectly as separator in preparser)
-- transform functions to function pointers in function parameters
- (net/ipv4/ip_output.c)
-- fix function pointer type display
-- check lcc test suite -> fix bitfield binary operations
-- check section alignment in C
-- fix invalid cast in comparison 'if (v == (int8_t)v)'
-- finish varargs.h support (gcc 3.2 testsuite issue)
-- fix static functions declared inside block
-- fix multiple unions init
-- sizeof, alignof, typeof can still generate code in some cases.
-- Fix the remaining libtcc memory leaks.
-- make libtcc fully reentrant (except for the compilation stage itself).
-
-Bound checking:
-
-- '-b' bug.
-- fix bound exit on RedHat 7.3
-- setjmp is not supported properly in bound checking.
-- fix bound check code with '&' on local variables (currently done
- only for local arrays).
-- bound checking and float/long long/struct copy code. bound
- checking and symbol + offset optimization
-
-Missing features:
-
-- disable-asm and disable-bcheck options
-- __builtin_expect()
-- improve '-E' option.
-- add '-MD' option
-- atexit (Nigel Horne)
-- packed attribute
-- C99: add variable size arrays (gcc 3.2 testsuite issue)
-- C99: add complex types (gcc 3.2 testsuite issue)
-- postfix compound literals (see 20010124-1.c)
-
-Optimizations:
-
-- suppress specific anonymous symbol handling
-- more parse optimizations (=even faster compilation)
-- memory alloc optimizations (=even faster compilation)
-- optimize VT_LOCAL + const
-- better local variables handling (needed for other targets)
-
-Not critical:
-
-- C99: fix multiple compound literals inits in blocks (ISOC99
- normative example - only relevant when using gotos! -> must add
- boolean variable to tell if compound literal was already
- initialized).
-- add PowerPC or ARM code generator and improve codegen for RISC (need
- to suppress VT_LOCAL and use a base register instead).
-- interactive mode / integrated debugger
-- fix preprocessor symbol redefinition
-- better constant opt (&&, ||, ?:)
-- add portable byte code generator and interpreter for other
- unsupported architectures.
-- C++: variable declaration in for, minimal 'class' support.
-- win32: __intxx. use resolve for bchecked malloc et al.
- check exception code (exception filter func).
-- handle void (__attribute__() *ptr)()
-
-Fixed (probably):
-
-- bug with defines:
- #define spin_lock(lock) do { } while (0)
- #define wq_spin_lock spin_lock
- #define TEST() wq_spin_lock(a)
-- typedefs can be structure fields
-- see bugfixes.diff + improvement.diff from Daniel Glockner
-- long long constant evaluation
-- add alloca()
-- gcc '-E' option.
-- #include_next support for /usr/include/limits ?
-- function pointers/lvalues in ? : (linux kernel net/core/dev.c)
-- win32: add __stdcall, check GetModuleHandle for dlls.

-
-<p>TinyCC (aka TCC) is a small but hyper fast C compiler. Unlike other C
-compilers, it is meant to be self-relying: you do not need an
-external assembler or linker because TCC does that for you.
-</p>
-<p>TCC compiles so <em>fast</em> that even for big projects <code>Makefile</code>s may
-not be necessary.
-</p>
-<p>TCC not only supports ANSI C, but also most of the new ISO C99
-standard and many GNUC extensions including inline assembly.
-</p>
-<p>TCC can also be used to make <em>C scripts</em>, i.e. pieces of C source
-that you run as a Perl or Python script. Compilation is so fast that
-your script will be as fast as if it was an executable.
-</p>
-<p>TCC can also automatically generate memory and bound checks
-(see section <a href="#SEC21">TinyCC Memory and Bound checks</a>) while allowing all C pointers operations. TCC can do
-these checks even if non patched libraries are used.
-</p>
-<p>With <code>libtcc</code>, you can use TCC as a backend for dynamic code
-generation (see section <a href="#SEC22">The <code>libtcc</code> library</a>).
-</p>
-<p>TCC mainly supports the i386 target on Linux and Windows. There are alpha
-ports for the ARM (<code>arm-tcc</code>) and the TMS320C67xx targets
-(<code>c67-tcc</code>). More information about the ARM port is available at
-<a href="http://lists.gnu.org/archive/html/tinycc-devel/2003-10/msg00044.html">http://lists.gnu.org/archive/html/tinycc-devel/2003-10/msg00044.html</a>.
-</p>
-<p>For usage on Windows, see also tcc-win32.txt.

-<p>Scripting:
-</p>
-<p>TCC can be invoked from <em>scripts</em>, just as shell scripts. You just
-need to add <code>#!/usr/local/bin/tcc -run</code> at the start of your C source:
-</p>
-<table><tr><td>&nbsp;</td><td><pre class="example">#!/usr/local/bin/tcc -run
-#include &lt;stdio.h&gt;
-
-int main()
-{
- printf(&quot;Hello World\n&quot;);
- return 0;
-}
-</pre></td></tr></table>
-
-<p>TCC can read C source code from <em>standard input</em> when &lsquo;<samp>-</samp>&rsquo; is used in
-place of &lsquo;<samp>infile</samp>&rsquo;. Example:
-</p>
-<table><tr><td>&nbsp;</td><td><pre class="example">echo 'main(){puts(&quot;hello&quot;);}' | tcc -run -

-<p>The TCC code generator directly generates linked binary code in one
-pass. It is rather unusual these days (see gcc for example which
-generates text assembly), but it can be very fast and surprisingly
-little complicated.
-</p>
-<p>The TCC code generator is register based. Optimization is only done at
-the expression level. No intermediate representation of expression is
-kept except the current values stored in the <em>value stack</em>.
-</p>
-<p>On x86, three temporary registers are used. When more registers are
-needed, one register is spilled into a new temporary variable on the stack.

-
-<p>When an expression is parsed, its value is pushed on the value stack
-(<var>vstack</var>). The top of the value stack is <var>vtop</var>. Each value
-stack entry is the structure <code>SValue</code>.
-</p>
-<p><code>SValue.t</code> is the type. <code>SValue.r</code> indicates how the value is
-currently stored in the generated code. It is usually a CPU register
-index (<code>REG_xxx</code> constants), but additional values and flags are
-defined:

-
-<p><code>vsetc()</code> and <code>vset()</code> pushes a new value on the value
-stack. If the previous <var>vtop</var> was stored in a very unsafe place(for
-example in the CPU flags), then some code is generated to put the
-previous <var>vtop</var> in a safe storage.
-</p>
-<p><code>vpop()</code> pops <var>vtop</var>. In some cases, it also generates cleanup
-code (for example if stacked floating point registers are used as on
-x86).
-</p>
-<p>The <code>gv(rc)</code> function generates code to evaluate <var>vtop</var> (the
-top value of the stack) into registers. <var>rc</var> selects in which
-register class the value should be put. <code>gv()</code> is the <em>most
-important function</em> of the code generator.
-</p>
-<p><code>gv2()</code> is the same as <code>gv()</code> but for the top two stack
-entries.

-@chapter Introduction
-
-TinyCC (aka TCC) is a small but hyper fast C compiler. Unlike other C
-compilers, it is meant to be self-relying: you do not need an
-external assembler or linker because TCC does that for you.
-
-TCC compiles so @emph{fast} that even for big projects @code{Makefile}s may
-not be necessary.
-
-TCC not only supports ANSI C, but also most of the new ISO C99
-standard and many GNUC extensions including inline assembly.
-
-TCC can also be used to make @emph{C scripts}, i.e. pieces of C source
-that you run as a Perl or Python script. Compilation is so fast that
-your script will be as fast as if it was an executable.
-
-TCC can also automatically generate memory and bound checks
-(@pxref{Bounds}) while allowing all C pointers operations. TCC can do
-these checks even if non patched libraries are used.
-
-With @code{libtcc}, you can use TCC as a backend for dynamic code
-generation (@pxref{Libtcc}).
-
-TCC mainly supports the i386 target on Linux and Windows. There are alpha
-ports for the ARM (@code{arm-tcc}) and the TMS320C67xx targets
-(@code{c67-tcc}). More information about the ARM port is available at
-@url{http://lists.gnu.org/archive/html/tinycc-devel/2003-10/msg00044.html}.
-
-For usage on Windows, see also tcc-win32.txt.
-
-@node Invoke
-@chapter Command line invocation
-
-@section Quick start
-
-@example
-@c man begin SYNOPSIS
-usage: tcc [options] [@var{infile1} @var{infile2}@dots{}] [@option{-run} @var{infile} @var{args}@dots{}]
-@c man end
-@end example
-
-@noindent
-@c man begin DESCRIPTION
-TCC options are a very much like gcc options. The main difference is that TCC
-can also execute directly the resulting program and give it runtime
-arguments.
-
-Here are some examples to understand the logic:
-
-@table @code
-@item @samp{tcc -run a.c}
-Compile @file{a.c} and execute it directly
-
-@item @samp{tcc -run a.c arg1}
-Compile a.c and execute it directly. arg1 is given as first argument to
-the @code{main()} of a.c.
-
-@item @samp{tcc a.c -run b.c arg1}
-Compile @file{a.c} and @file{b.c}, link them together and execute them. arg1 is given
-as first argument to the @code{main()} of the resulting program.
-@ignore
-Because multiple C files are specified, @option{--} are necessary to clearly
-separate the program arguments from the TCC options.
-@end ignore
-
-@item @samp{tcc -o myprog a.c b.c}
-Compile @file{a.c} and @file{b.c}, link them and generate the executable @file{myprog}.
-
-@item @samp{tcc -o myprog a.o b.o}
-link @file{a.o} and @file{b.o} together and generate the executable @file{myprog}.
-
-@item @samp{tcc -c a.c}
-Compile @file{a.c} and generate object file @file{a.o}.
-
-@item @samp{tcc -c asmfile.S}
-Preprocess with C preprocess and assemble @file{asmfile.S} and generate
-object file @file{asmfile.o}.
-
-@item @samp{tcc -c asmfile.s}
-Assemble (but not preprocess) @file{asmfile.s} and generate object file
-@file{asmfile.o}.
-
-@item @samp{tcc -r -o ab.o a.c b.c}
-Compile @file{a.c} and @file{b.c}, link them together and generate the object file @file{ab.o}.
-
-@end table
-
-Scripting:
-
-TCC can be invoked from @emph{scripts}, just as shell scripts. You just
-need to add @code{#!/usr/local/bin/tcc -run} at the start of your C source:
-
-@example
-#!/usr/local/bin/tcc -run
-#include <stdio.h>
-
-int main()
-@{
- printf("Hello World\n");
- return 0;
-@}
-@end example
-
-TCC can read C source code from @emph{standard input} when @option{-} is used in
-place of @option{infile}. Example:
-
-@example
-echo 'main()@{puts("hello");@}' | tcc -run -
-@end example
-@c man end
-
-@section Option summary
-
-General Options:
-
-@c man begin OPTIONS
-@table @option
-@item -v
-Display current TCC version, increase verbosity.
-
-@item -c
-Generate an object file (@option{-o} option must also be given).
-
-@item -o outfile
-Put object file, executable, or dll into output file @file{outfile}.
-
-@item -Bdir
-Set the path where the tcc internal libraries can be found (default is
-@file{PREFIX/lib/tcc}).
-
-@item -bench
-Output compilation statistics.
-
-@item -run source [args...]
-Compile file @var{source} and run it with the command line arguments
-@var{args}. In order to be able to give more than one argument to a
-script, several TCC options can be given @emph{after} the
-@option{-run} option, separated by spaces. Example:
-
-@example
-tcc "-run -L/usr/X11R6/lib -lX11" ex4.c
-@end example
-
-In a script, it gives the following header:
-
-@example
-#!/usr/local/bin/tcc -run -L/usr/X11R6/lib -lX11
-#include <stdlib.h>
-int main(int argc, char **argv)
-@{
- ...
-@}
-@end example
-
-@end table
-
-Preprocessor options:
-
-@table @option
-@item -Idir
-Specify an additional include path. Include paths are searched in the
-order they are specified.
-
-System include paths are always searched after. The default system
-include paths are: @file{/usr/local/include}, @file{/usr/include}
-and @file{PREFIX/lib/tcc/include}. (@file{PREFIX} is usually
-@file{/usr} or @file{/usr/local}).
-
-@item -Dsym[=val]
-Define preprocessor symbol @samp{sym} to
-val. If val is not present, its value is @samp{1}. Function-like macros can
-also be defined: @option{-DF(a)=a+1}
-
-@item -Usym
-Undefine preprocessor symbol @samp{sym}.
-@end table
-
-Compilation flags:
-
-Note: each of the following warning options has a negative form beginning with
-@option{-fno-}.
-
-@table @option
-@item -funsigned-char
-Let the @code{char} type be unsigned.
-
-@item -fsigned-char
-Let the @code{char} type be signed.
-
-@item -fno-common
-Do not generate common symbols for uninitialized data.
-
-@item -fleading-underscore
-Add a leading underscore at the beginning of each C symbol.
-
-@end table
-
-Warning options:
-
-@table @option
-@item -w
-Disable all warnings.
-
-@end table
-
-Note: each of the following warning options has a negative form beginning with
-@option{-Wno-}.
-
-@table @option
-@item -Wimplicit-function-declaration
-Warn about implicit function declaration.
-
-@item -Wunsupported
-Warn about unsupported GCC features that are ignored by TCC.

-@option{-Wwrite-strings}.
-
-@end table
-
-Linker options:
-
-@table @option
-@item -Ldir
-Specify an additional static library path for the @option{-l} option. The
-default library paths are @file{/usr/local/lib}, @file{/usr/lib} and @file{/lib}.
-
-@item -lxxx
-Link your program with dynamic library libxxx.so or static library
-libxxx.a. The library is searched in the paths specified by the
-@option{-L} option.
-
-@item -shared
-Generate a shared library instead of an executable (@option{-o} option
-must also be given).
-
-@item -static
-Generate a statically linked executable (default is a shared linked
-executable) (@option{-o} option must also be given).
-
-@item -rdynamic
-Export global symbols to the dynamic linker. It is useful when a library
-opened with @code{dlopen()} needs to access executable symbols.
-
-@item -r
-Generate an object file combining all input files (@option{-o} option must
-also be given).
-
-@item -Wl,-Ttext,address
-Set the start of the .text section to @var{address}.

-
-Debugger options:
-
-@table @option
-@item -g
-Generate run time debug information so that you get clear run time

-invalid pointer} instead of the laconic @code{Segmentation
-fault}.
-
-@item -b
-Generate additional support code to check
-memory allocations and array/pointer bounds. @option{-g} is implied. Note
-that the generated code is slower and bigger in this case.
-
-@item -bt N
-Display N callers in stack traces. This is useful with @option{-g} or
-@option{-b}.
-
-@end table
-
-Note: GCC options @option{-Ox}, @option{-fx} and @option{-mx} are
-ignored.

-@section ISOC99 extensions
-
-TCC implements many features of the new C standard: ISO C99. Currently
-missing items are: complex and imaginary numbers and variable length
-arrays.
-
-Currently implemented ISOC99 features:
-
-@itemize
-
-@item 64 bit @code{long long} types are fully supported.
-
-@item The boolean type @code{_Bool} is supported.
-
-@item @code{__func__} is a string variable containing the current
-function name.
-
-@item Variadic macros: @code{__VA_ARGS__} can be used for
- function-like macros:
-@example
- #define dprintf(level, __VA_ARGS__) printf(__VA_ARGS__)
-@end example
-
-@noindent
-@code{dprintf} can then be used with a variable number of parameters.
-
-@item Declarations can appear anywhere in a block (as in C++).
-
-@item Array and struct/union elements can be initialized in any order by
- using designators:
-@example
- struct @{ int x, y; @} st[10] = @{ [0].x = 1, [0].y = 2 @};
-
- int tab[10] = @{ 1, 2, [5] = 5, [9] = 9@};
-@end example
-
-@item Compound initializers are supported:
-@example
- int *p = (int [])@{ 1, 2, 3 @};
-@end example
-to initialize a pointer pointing to an initialized array. The same
-works for structures and strings.
-
-@item Hexadecimal floating point constants are supported:
-@example
- double d = 0x1234p10;
-@end example
-
-@noindent
-is the same as writing
-@example
- double d = 4771840.0;
-@end example
-
-@item @code{inline} keyword is ignored.
-
-@item @code{restrict} keyword is ignored.
-@end itemize
-
-@section GNU C extensions
-
-TCC implements some GNU C extensions:
-
-@itemize
-
-@item array designators can be used without '=':
-@example
- int a[10] = @{ [0] 1, [5] 2, 3, 4 @};
-@end example
-
-@item Structure field designators can be a label:
-@example
- struct @{ int x, y; @} st = @{ x: 1, y: 1@};
-@end example
-instead of
-@example
- struct @{ int x, y; @} st = @{ .x = 1, .y = 1@};
-@end example
-
-@item @code{\e} is ASCII character 27.
-
-@item case ranges : ranges can be used in @code{case}s:
-@example
- switch(a) @{
- case 1 @dots{} 9:
- printf("range 1 to 9\n");
- break;
- default:
- printf("unexpected\n");
- break;
- @}
-@end example
-
-@cindex aligned attribute
-@cindex packed attribute
-@cindex section attribute
-@cindex unused attribute
-@cindex cdecl attribute
-@cindex stdcall attribute
-@cindex regparm attribute
-@cindex dllexport attribute
-
-@item The keyword @code{__attribute__} is handled to specify variable or
-function attributes. The following attributes are supported:
- @itemize
-
- @item @code{aligned(n)}: align a variable or a structure field to n bytes
-(must be a power of two).
-
- @item @code{packed}: force alignment of a variable or a structure field to
- 1.
-
- @item @code{section(name)}: generate function or data in assembly section
-name (name is a string containing the section name) instead of the default
-section.
-
- @item @code{unused}: specify that the variable or the function is unused.
-
- @item @code{cdecl}: use standard C calling convention (default).
-
- @item @code{stdcall}: use Pascal-like calling convention.
-
- @item @code{regparm(n)}: use fast i386 calling convention. @var{n} must be
-between 1 and 3. The first @var{n} function parameters are respectively put in
-registers @code{%eax}, @code{%edx} and @code{%ecx}.
-
- @item @code{dllexport}: export function from dll/executable (win32 only)
-
- @end itemize
-
-Here are some examples:
-@example
- int a __attribute__ ((aligned(8), section(".mysection")));
-@end example
-
-@noindent
-align variable @code{a} to 8 bytes and put it in section @code{.mysection}.
-
-@example
- int my_add(int a, int b) __attribute__ ((section(".mycodesection")))
- @{
- return a + b;
- @}
-@end example
-
-@noindent
-generate function @code{my_add} in section @code{.mycodesection}.
-
-@item GNU style variadic macros:
-@example
- #define dprintf(fmt, args@dots{}) printf(fmt, ## args)
-
- dprintf("no arg\n");
- dprintf("one arg %d\n", 1);
-@end example
-
-@item @code{__FUNCTION__} is interpreted as C99 @code{__func__}
-(so it has not exactly the same semantics as string literal GNUC
-where it is a string literal).
-
-@item The @code{__alignof__} keyword can be used as @code{sizeof}
-to get the alignment of a type or an expression.
-
-@item The @code{typeof(x)} returns the type of @code{x}.
-@code{x} is an expression or a type.
-
-@item Computed gotos: @code{&&label} returns a pointer of type
-@code{void *} on the goto label @code{label}. @code{goto *expr} can be
-used to jump on the pointer resulting from @code{expr}.
-
-@item Inline assembly with asm instruction:
-@cindex inline assembly
-@cindex assembly, inline
-@cindex __asm__
-@example
-static inline void * my_memcpy(void * to, const void * from, size_t n)
-@{
-int d0, d1, d2;
-__asm__ __volatile__(
- "rep ; movsl\n\t"
- "testb $2,%b4\n\t"
- "je 1f\n\t"
- "movsw\n"
- "1:\ttestb $1,%b4\n\t"
- "je 2f\n\t"
- "movsb\n"
- "2:"
- : "=&c" (d0), "=&D" (d1), "=&S" (d2)
- :"0" (n/4), "q" (n),"1" ((long) to),"2" ((long) from)
- : "memory");
-return (to);
-@}
-@end example
-
-@noindent
-@cindex gas
-TCC includes its own x86 inline assembler with a @code{gas}-like (GNU
-assembler) syntax. No intermediate files are generated. GCC 3.x named
-operands are supported.
-
-@item @code{__builtin_types_compatible_p()} and @code{__builtin_constant_p()}
-are supported.
-
-@item @code{#pragma pack} is supported for win32 compatibility.

-@chapter TinyCC Assembler
-
-Since version 0.9.16, TinyCC integrates its own assembler. TinyCC
-assembler supports a gas-like syntax (GNU assembler). You can
-desactivate assembler support if you want a smaller TinyCC executable
-(the C compiler does not rely on the assembler).
-
-TinyCC Assembler is used to handle files with @file{.S} (C
-preprocessed assembler) and @file{.s} extensions. It is also used to
-handle the GNU inline assembler with the @code{asm} keyword.
-
-@section Syntax
-
-TinyCC Assembler supports most of the gas syntax. The tokens are the
-same as C.
-
-@itemize
-
-@item C and C++ comments are supported.
-
-@item Identifiers are the same as C, so you cannot use '.' or '$'.
-
-@item Only 32 bit integer numbers are supported.
-
-@end itemize
-
-@section Expressions
-
-@itemize
-
-@item Integers in decimal, octal and hexa are supported.
-
-@item Unary operators: +, -, ~.
-
-@item Binary operators in decreasing priority order:
-
-@enumerate
-@item *, /, %
-@item &, |, ^
-@item +, -
-@end enumerate
-
-@item A value is either an absolute number or a label plus an offset.
-All operators accept absolute values except '+' and '-'. '+' or '-' can be
-used to add an offset to a label. '-' supports two labels only if they
-are the same or if they are both defined and in the same section.
-
-@end itemize
-
-@section Labels
-
-@itemize
-
-@item All labels are considered as local, except undefined ones.
-
-@item Numeric labels can be used as local @code{gas}-like labels.
-They can be defined several times in the same source. Use 'b'
-(backward) or 'f' (forward) as suffix to reference them:
-
-@example
- 1:
- jmp 1b /* jump to '1' label before */
- jmp 1f /* jump to '1' label after */

-@cindex assembler
-
-All X86 opcodes are supported. Only ATT syntax is supported (source

-@section ELF file generation
-@cindex ELF
-
-TCC can directly output relocatable ELF files (object files),
-executable ELF files and dynamic ELF libraries without relying on an
-external linker.
-
-Dynamic ELF libraries can be output but the C compiler does not generate
-position independent code (PIC). It means that the dynamic library
-code generated by TCC cannot be factorized among processes yet.
-
-TCC linker eliminates unreferenced object code in libraries. A single pass is
-done on the object and library list, so the order in which object files and
-libraries are specified is important (same constraint as GNU ld). No grouping
-options (@option{--start-group} and @option{--end-group}) are supported.
-
-@section ELF file loader
-
-TCC can load ELF object files, archives (.a files) and dynamic
-libraries (.so).
-
-@section PE-i386 file generation
-@cindex PE-i386
-
-TCC for Windows supports the native Win32 executable file format (PE-i386). It
-generates EXE files (console and gui) and DLL files.
-
-For usage on Windows, see also tcc-win32.txt.

-@cindex scripts, linker
-@cindex linker scripts
-@cindex GROUP, linker command

-
-Because on many Linux systems some dynamic libraries (such as
-@file{/usr/lib/libc.so}) are in fact GNU ld link scripts (horrible!),
-the TCC linker also supports a subset of GNU ld scripts.
-
-The @code{GROUP} and @code{FILE} commands are supported. @code{OUTPUT_FORMAT}
-and @code{TARGET} are ignored.
-
-Example from @file{/usr/lib/libc.so}:
-@example
-/* GNU ld script
- Use the shared library, but some functions are only in
- the static library, so try that secondarily. */
-GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a )

-@node Bounds
-@chapter TinyCC Memory and Bound checks
-@cindex bound checks
-@cindex memory checks
-
-This feature is activated with the @option{-b} (@pxref{Invoke}).
-
-Note that pointer size is @emph{unchanged} and that code generated
-with bound checks is @emph{fully compatible} with unchecked
-code. When a pointer comes from unchecked code, it is assumed to be
-valid. Even very obscure C code with casts should work correctly.
-
-For more information about the ideas behind this method, see
-@url{http://www.doc.ic.ac.uk/~phjk/BoundsChecking.html}.
-
-Here are some examples of caught errors:
-
-@table @asis
-
-@item Invalid range with standard string function:
-@example
-@{
- char tab[10];
- memset(tab, 0, 11);
-@}
-@end example
-
-@item Out of bounds-error in global or local arrays:
-@example
-@{
- int tab[10];
- for(i=0;i<11;i++) @{
- sum += tab[i];
- @}
-@}
-@end example
-
-@item Out of bounds-error in malloc'ed data:
-@example
-@{
- int *tab;
- tab = malloc(20 * sizeof(int));
- for(i=0;i<21;i++) @{
- sum += tab4[i];

-@chapter The @code{libtcc} library
-
-The @code{libtcc} library enables you to use TCC as a backend for
-dynamic code generation.
-
-Read the @file{libtcc.h} to have an overview of the API. Read
-@file{libtcc_test.c} to have a very simple example.
-
-The idea consists in giving a C string containing the program you want
-to compile directly to @code{libtcc}. Then you can access to any global
-symbol (function or variable) defined.
-
-@node devel
-@chapter Developer's guide
-
-This chapter gives some hints to understand how TCC works. You can skip
-it if you do not intend to modify the TCC code.
-
-@section File reading
-
-The @code{BufferedFile} structure contains the context needed to read a
-file, including the current line number. @code{tcc_open()} opens a new
-file and @code{tcc_close()} closes it. @code{inp()} returns the next
-character.
-
-@section Lexer
-
-@code{next()} reads the next token in the current
-file. @code{next_nomacro()} reads the next token without macro
-expansion.
-
-@code{tok} contains the current token (see @code{TOK_xxx})
-constants. Identifiers and keywords are also keywords. @code{tokc}
-contains additional infos about the token (for example a constant value
-if number or string token).
-
-@section Parser
-
-The parser is hardcoded (yacc is not necessary). It does only one pass,
-except:
-
-@itemize
-
-@item For initialized arrays with unknown size, a first pass
-is done to count the number of elements.
-
-@item For architectures where arguments are evaluated in
-reverse order, a first pass is done to reverse the argument order.
-
-@end itemize
-
-@section Types
-
-The types are stored in a single 'int' variable. It was choosen in the
-first stages of development when tcc was much simpler. Now, it may not
-be the best solution.
-
-@example
-#define VT_INT 0 /* integer type */
-#define VT_BYTE 1 /* signed byte type */
-#define VT_SHORT 2 /* short type */
-#define VT_VOID 3 /* void type */
-#define VT_PTR 4 /* pointer */
-#define VT_ENUM 5 /* enum definition */
-#define VT_FUNC 6 /* function type */
-#define VT_STRUCT 7 /* struct/union definition */
-#define VT_FLOAT 8 /* IEEE float */
-#define VT_DOUBLE 9 /* IEEE double */
-#define VT_LDOUBLE 10 /* IEEE long double */
-#define VT_BOOL 11 /* ISOC99 boolean type */
-#define VT_LLONG 12 /* 64 bit integer */
-#define VT_LONG 13 /* long integer (NEVER USED as type, only
- during parsing) */
-#define VT_BTYPE 0x000f /* mask for basic type */
-#define VT_UNSIGNED 0x0010 /* unsigned type */
-#define VT_ARRAY 0x0020 /* array type (also has VT_PTR) */
-#define VT_BITFIELD 0x0040 /* bitfield modifier */
-
-#define VT_STRUCT_SHIFT 16 /* structure/enum name shift (16 bits left) */
-@end example
-
-When a reference to another type is needed (for pointers, functions and
-structures), the @code{32 - VT_STRUCT_SHIFT} high order bits are used to
-store an identifier reference.
-
-The @code{VT_UNSIGNED} flag can be set for chars, shorts, ints and long
-longs.
-
-Arrays are considered as pointers @code{VT_PTR} with the flag
-@code{VT_ARRAY} set.
-
-The @code{VT_BITFIELD} flag can be set for chars, shorts, ints and long
-longs. If it is set, then the bitfield position is stored from bits
-VT_STRUCT_SHIFT to VT_STRUCT_SHIFT + 5 and the bit field size is stored
-from bits VT_STRUCT_SHIFT + 6 to VT_STRUCT_SHIFT + 11.
-
-@code{VT_LONG} is never used except during parsing.
-
-During parsing, the storage of an object is also stored in the type
-integer:
-
-@example
-#define VT_EXTERN 0x00000080 /* extern definition */
-#define VT_STATIC 0x00000100 /* static variable */
-#define VT_TYPEDEF 0x00000200 /* typedef definition */
-@end example
-
-@section Symbols
-
-All symbols are stored in hashed symbol stacks. Each symbol stack
-contains @code{Sym} structures.
-
-@code{Sym.v} contains the symbol name (remember
-an idenfier is also a token, so a string is never necessary to store
-it). @code{Sym.t} gives the type of the symbol. @code{Sym.r} is usually
-the register in which the corresponding variable is stored. @code{Sym.c} is
-usually a constant associated to the symbol.
-
-Four main symbol stacks are defined:
-
-@table @code
-
-@item define_stack
-for the macros (@code{#define}s).
-
-@item global_stack
-for the global variables, functions and types.
-
-@item local_stack
-for the local variables, functions and types.
-
-@item global_label_stack
-for the local labels (for @code{goto}).
-
-@item label_stack
-for GCC block local labels (see the @code{__label__} keyword).
-
-@end table
-
-@code{sym_push()} is used to add a new symbol in the local symbol
-stack. If no local symbol stack is active, it is added in the global
-symbol stack.
-
-@code{sym_pop(st,b)} pops symbols from the symbol stack @var{st} until
-the symbol @var{b} is on the top of stack. If @var{b} is NULL, the stack
-is emptied.
-
-@code{sym_find(v)} return the symbol associated to the identifier
-@var{v}. The local stack is searched first from top to bottom, then the
-global stack.
-
-@section Sections
-
-The generated code and datas are written in sections. The structure
-@code{Section} contains all the necessary information for a given
-section. @code{new_section()} creates a new section. ELF file semantics
-is assumed for each section.
-
-The following sections are predefined:
-
-@table @code
-
-@item text_section
-is the section containing the generated code. @var{ind} contains the
-current position in the code section.
-
-@item data_section
-contains initialized data
-
-@item bss_section
-contains uninitialized data
-
-@item bounds_section
-@itemx lbounds_section
-are used when bound checking is activated
-
-@item stab_section
-@itemx stabstr_section
-are used when debugging is actived to store debug information
-
-@item symtab_section
-@itemx strtab_section
-contain the exported symbols (currently only used for debugging).

-@section Code generation
-@cindex code generation
-
-@subsection Introduction
-
-The TCC code generator directly generates linked binary code in one
-pass. It is rather unusual these days (see gcc for example which
-generates text assembly), but it can be very fast and surprisingly
-little complicated.
-
-The TCC code generator is register based. Optimization is only done at
-the expression level. No intermediate representation of expression is
-kept except the current values stored in the @emph{value stack}.
-
-On x86, three temporary registers are used. When more registers are
-needed, one register is spilled into a new temporary variable on the stack.
-
-@subsection The value stack
-@cindex value stack, introduction
-
-When an expression is parsed, its value is pushed on the value stack
-(@var{vstack}). The top of the value stack is @var{vtop}. Each value
-stack entry is the structure @code{SValue}.
-
-@code{SValue.t} is the type. @code{SValue.r} indicates how the value is
-currently stored in the generated code. It is usually a CPU register
-index (@code{REG_xxx} constants), but additional values and flags are
-defined:
-
-@example
-#define VT_CONST 0x00f0
-#define VT_LLOCAL 0x00f1
-#define VT_LOCAL 0x00f2
-#define VT_CMP 0x00f3
-#define VT_JMP 0x00f4
-#define VT_JMPI 0x00f5
-#define VT_LVAL 0x0100
-#define VT_SYM 0x0200
-#define VT_MUSTCAST 0x0400
-#define VT_MUSTBOUND 0x0800
-#define VT_BOUNDED 0x8000
-#define VT_LVAL_BYTE 0x1000
-#define VT_LVAL_SHORT 0x2000
-#define VT_LVAL_UNSIGNED 0x4000
-#define VT_LVAL_TYPE (VT_LVAL_BYTE | VT_LVAL_SHORT | VT_LVAL_UNSIGNED)
-@end example
-
-@table @code
-
-@item VT_CONST
-indicates that the value is a constant. It is stored in the union
-@code{SValue.c}, depending on its type.
-
-@item VT_LOCAL
-indicates a local variable pointer at offset @code{SValue.c.i} in the
-stack.
-
-@item VT_CMP
-indicates that the value is actually stored in the CPU flags (i.e. the
-value is the consequence of a test). The value is either 0 or 1. The
-actual CPU flags used is indicated in @code{SValue.c.i}.
-
-If any code is generated which destroys the CPU flags, this value MUST be
-put in a normal register.
-
-@item VT_JMP
-@itemx VT_JMPI
-indicates that the value is the consequence of a conditional jump. For VT_JMP,
-it is 1 if the jump is taken, 0 otherwise. For VT_JMPI it is inverted.
-
-These values are used to compile the @code{||} and @code{&&} logical
-operators.
-
-If any code is generated, this value MUST be put in a normal
-register. Otherwise, the generated code won't be executed if the jump is
-taken.
-
-@item VT_LVAL
-is a flag indicating that the value is actually an lvalue (left value of
-an assignment). It means that the value stored is actually a pointer to
-the wanted value.
-
-Understanding the use @code{VT_LVAL} is very important if you want to
-understand how TCC works.
-
-@item VT_LVAL_BYTE
-@itemx VT_LVAL_SHORT
-@itemx VT_LVAL_UNSIGNED
-if the lvalue has an integer type, then these flags give its real
-type. The type alone is not enough in case of cast optimisations.
-
-@item VT_LLOCAL
-is a saved lvalue on the stack. @code{VT_LLOCAL} should be eliminated
-ASAP because its semantics are rather complicated.
-
-@item VT_MUSTCAST
-indicates that a cast to the value type must be performed if the value
-is used (lazy casting).
-
-@item VT_SYM
-indicates that the symbol @code{SValue.sym} must be added to the constant.
-
-@item VT_MUSTBOUND
-@itemx VT_BOUNDED
-are only used for optional bound checking.
-
-@end table
-
-@subsection Manipulating the value stack
-@cindex value stack
-
-@code{vsetc()} and @code{vset()} pushes a new value on the value
-stack. If the previous @var{vtop} was stored in a very unsafe place(for
-example in the CPU flags), then some code is generated to put the
-previous @var{vtop} in a safe storage.
-
-@code{vpop()} pops @var{vtop}. In some cases, it also generates cleanup
-code (for example if stacked floating point registers are used as on
-x86).
-
-The @code{gv(rc)} function generates code to evaluate @var{vtop} (the
-top value of the stack) into registers. @var{rc} selects in which
-register class the value should be put. @code{gv()} is the @emph{most
-important function} of the code generator.
-
-@code{gv2()} is the same as @code{gv()} but for the top two stack
-entries.
-

-must generate the binary integer operation @var{op} on the two top
-entries of the stack which are guaranted to contain integer types.
-
-The result value should be put on the stack.
-
-@item gen_opf(op)
-same as @code{gen_opi()} for floating point operations. The two top

-@cindex constant propagation
-@cindex strength reduction
-@cindex comparison operators
-@cindex caching processor flags
-@cindex flags, caching
-@cindex jump optimization
-Constant propagation is done for all operations. Multiplications and
-divisions are optimized to shifts when appropriate. Comparison
-operators are optimized by maintaining a special cache for the
-processor flags. &&, || and ! are optimized by maintaining a special
-'jump target' value. No other jump optimization is currently performed
-because it would require to store the code in a more abstract fashion.
