-Android Port of LÖVE, the awesome 2D game engine LÖVE (http://love2d.org)
-Copyright (c) 2013-2014 Martin Felis <martin@fysx.org>
+Android Port of LÖVE, an awesome 2D game engine for Lua (http://love2d.org)  
+Copyright (c) 2006-2023 LOVE Development Team
+
+![Build Status](https://github.com/love2d/love-android/workflows/build/badge.svg)
+
+Download:
+---------
+
+You can download pre-built Android packages from https://github.com/love2d/love/releases/latest that allow
+you to run .love files by opening them using a file manager of your choice.
+
+Important:
+----------
+
+If you want to build from source, make sure to clone the submodules too. Often errors include missing
+liblove.so and "Missing LÖVE" error when building. A proper way to clone this repository is:
+
+```
+git clone --recurse-submodules https://github.com/love2d/love-android
+```
+
+Add `-b <branch/tag name>` and `--depth 1` if needed.
+
+If you already cloned the repository but forgot to initialize the submodules, execute:
+
+```
+git submodule sync --recursive
+git submodule update --init --force --recursive
+```
+
+In the repository directory. For the last command, add `--depth 1` if needed.
 
 Instructions:
 -------------
 
-For detailed instructions please refer to the [wiki](wiki).
+Detailed instructions can be viewed at https://github.com/love2d/love-android/wiki
 
 Quick Start:
 ------------
 
-Install the Android NDK and the Android SDK with SDK API 12 and run
+Before you start, install JDK 17 (not later not earlier). If you intend to build from Android Studio, skip this step as
+Android Studio bundles its own JDK 17.
 
-    ndk-build
+Install Android SDK with SDK API 34 (34.x.y) and Android NDK 25.2.9519653, set the environment variable
+`ANDROID_SDK_ROOT` to your Android SDK location and run:
 
-and after that
+```
+$ ./gradlew assembleNormalRecord
+```
 
-    ant debug
+in the root folder of this project. This should give you an .apk file in the `app/build/outputs/apk/normalRecord`
+subdirectory that you can then sign and install on your phone. The `normalRecord` .apk variant is what you normally have
+when downloading APK from https://love2d.org.
 
-in the root folder of this project or load the project using Eclipse and
-compile/run it using Eclipse.
+If you want to put your game inside the APK, you can either:
 
-This should give you a .apk file in the bin/ subdirectory that you can then
-install on your phone.
+1. Put all your games in `app/src/embed/assets` such that your `main.lua` path is `app/src/embed/assets/main.lua`; or
+2. Put your zipped \*.love in `app/src/embed/assets` with name `game.love`
+
+And change the application id, application version string and codes, application display name, and the icons (see
+[Game Packaging Wiki](https://github.com/love2d/love-android/wiki/Game-Packaging). Afterwards,
+run either `gradlew assembleEmbedNoRecordRelease` (or `gradlew assembleEmbedRecordRelease` if your game uses microphone) to
+generate APK which you can install or `gradlew bundleEmbedNoRecordRelease` (or `gradlew bundleEmbedRecordRelease`) to generate
+AAB which you can upload to Play Store.
+
+Alternatively, you can install Android Studio **2022.3.1** or later. After opening it for the first time, open its SDK Manager
+and on the tab "SDK Tools", tick "Show Package Details" then select NDK (Side By Side) version 25.2.9519653. After that, open
+the repository root.
+
+Notice: Previously, the embed + APKTool method is preferred, but recent announcements by Google render that method obsolete.
 
 Bugs:
 -----
 
-Bugs and feature requests should be reported to the [issue
-tracker](issues).
+Bugs and/or feature requests should be reported to the issue tracker at:
+* https://github.com/love2d/love-android/issues - LÖVE-Android-specific issues
+* https://github.com/love2d/love/issues - for LÖVE in general
+
+Note: If in doubt, fill an issue report to https://github.com/love2d/love/issues. We'll transfer the issue to this repository as needed.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt

-</p>
-
-<h2 id="LuaJIT-1.1.0">LuaJIT 1.1.0 &mdash; 2006-03-13</h2>
-<ul>
-<li>Merged with Lua 5.1 (final).</li>
-
-<li>New JIT call frame setup:
-<ul>
-<li>The C stack is kept 16 byte aligned (faster).
-Mandatory for Mac OS X on Intel, too.</li>
-<li>Faster calling conventions for internal C helper functions.</li>
-<li>Better instruction scheduling for function prologue, OP_CALL and
-OP_RETURN.</li>
-</ul></li>
-
-<li>Miscellaneous optimizations:
-<ul>
-<li>Faster loads of FP constants. Remove narrow-to-wide store-to-load
-forwarding stalls.</li>
-<li>Use (scalar) SSE2 ops (if the CPU supports it) to speed up slot moves
-and FP to integer conversions.</li>
-<li>Optimized the two-argument form of <tt>OP_CONCAT</tt> (<tt>a..b</tt>).</li>
-<li>Inlined <tt>OP_MOD</tt> (<tt>a%b</tt>).
-With better accuracy than the C variant, too.</li>
-<li>Inlined <tt>OP_POW</tt> (<tt>a^b</tt>). Unroll <tt>x^k</tt> or
-use <tt>k^x = 2^(log2(k)*x)</tt> or call <tt>pow()</tt>.</li>
-</ul></li>
-
-<li>Changes in the optimizer:
-<ul>
-<li>Improved hinting for table keys derived from table values
-(<tt>t1[t2[x]]</tt>).</li>
-<li>Lookup hinting now works with arbitrary object types and
-supports index chains, too.</li>
-<li>Generate type hints for arithmetic and comparison operators,
-OP_LEN, OP_CONCAT and OP_FORPREP.</li>
-<li>Remove several hint definitions in favour of a generic COMBINE hint.</li>
-<li>Complete rewrite of <tt>jit.opt_inline</tt> module
-(ex <tt>jit.opt_lib</tt>).</li>
-</ul></li>
-
-<li>Use adaptive deoptimization:
-<ul>
-<li>If runtime verification of a contract fails, the affected
-instruction is recompiled and patched on-the-fly.
-Regular programs will trigger deoptimization only occasionally.</li>
-<li>This avoids generating code for uncommon fallback cases
-most of the time. Generated code is up to 30% smaller compared to
-LuaJIT&nbsp;1.0.3.</li>
-<li>Deoptimization is used for many opcodes and contracts:
-<ul>
-<li>OP_CALL, OP_TAILCALL: type mismatch for callable.</li>
-<li>Inlined calls: closure mismatch, parameter number and type mismatches.</li>
-<li>OP_GETTABLE, OP_SETTABLE: table or key type and range mismatches.</li>
-<li>All arithmetic and comparison operators, OP_LEN, OP_CONCAT,
-OP_FORPREP: operand type and range mismatches.</li>
-</ul></li>
-<li>Complete redesign of the debug and traceback info
-(bytecode &harr; mcode) to support deoptimization.
-Much more flexible and needs only 50% of the space.</li>
-<li>The modules <tt>jit.trace</tt>, <tt>jit.dumphints</tt> and
-<tt>jit.dump</tt> handle deoptimization.</li>
-</ul></li>
-
-<li>Inlined many popular library functions
-(for commonly used arguments only):
-<ul>
-<li>Most <tt>math.*</tt> functions (the 18 most used ones)
-[2x-10x faster].</li>
-<li><tt>string.len</tt>, <tt>string.sub</tt> and <tt>string.char</tt>
-[2x-10x faster].</li>
-<li><tt>table.insert</tt>, <tt>table.remove</tt> and <tt>table.getn</tt>
-[3x-5x faster].</li>
-<li><tt>coroutine.yield</tt> and <tt>coroutine.resume</tt>
-[3x-5x faster].</li>
-<li><tt>pairs</tt>, <tt>ipairs</tt> and the corresponding iterators
-[8x-15x faster].</li>
-</ul></li>
-
-<li>Changes in the core and loadable modules and the stand-alone executable:
-<ul>
-<li>Added <tt>jit.version</tt>, <tt>jit.version_num</tt>
-and <tt>jit.arch</tt>.</li>
-<li>Reorganized some internal API functions (<tt>jit.util.*mcode*</tt>).</li>
-<li>The <tt>-j dump</tt> output now shows JSUB names, too.</li>
-<li>New x86 disassembler module written in pure Lua. No dependency
-on ndisasm anymore. Flexible API, very compact (500 lines)
-and complete (x87, MMX, SSE, SSE2, SSE3, SSSE3, privileged instructions).</li>
-<li><tt>luajit -v</tt> prints the LuaJIT version and copyright
-on a separate line.</li>
-</ul></li>
-
-<li>Added SSE, SSE2, SSE3 and SSSE3 support to DynASM.</li>
-<li>Miscellaneous doc changes. Added a section about
-<a href="install.html#embedding">embedding LuaJIT</a>.</li>
-</ul>
-<p>

-LuaJIT is fully upwards-compatible with Lua 5.1. It supports all
-<a href="http://www.lua.org/manual/5.1/manual.html#5"><span class="ext">&raquo;</span>&nbsp;standard Lua
-library functions</a> and the full set of
-<a href="http://www.lua.org/manual/5.1/manual.html#3"><span class="ext">&raquo;</span>&nbsp;Lua/C API
-functions</a>.
-</p>
-<p>
-LuaJIT is also fully ABI-compatible to Lua 5.1 at the linker/dynamic
-loader level. This means you can compile a C&nbsp;module against the
-standard Lua headers and load the same shared library from either Lua
-or LuaJIT.
-</p>
-<p>
-LuaJIT extends the standard Lua VM with new functionality and adds
-several extension modules. Please note this page is only about
-<em>functional</em> enhancements and not about performance enhancements,
-such as the optimized VM, the faster interpreter or the JIT compiler.
-</p>
-
-<h2 id="modules">Extensions Modules</h2>
-<p>
-LuaJIT comes with several built-in extension modules:
-</p>
-
-<h3 id="bit"><tt>bit.*</tt> &mdash; Bitwise operations</h3>
-<p>
-LuaJIT supports all bitwise operations as defined by
-<a href="http://bitop.luajit.org"><span class="ext">&raquo;</span>&nbsp;Lua BitOp</a>:
-</p>
-<pre class="code">
-bit.tobit  bit.tohex  bit.bnot    bit.band bit.bor  bit.bxor
-bit.lshift bit.rshift bit.arshift bit.rol  bit.ror  bit.bswap
-</pre>
-<p>
-This module is a LuaJIT built-in &mdash; you don't need to download or
-install Lua BitOp. The Lua BitOp site has full documentation for all
-<a href="http://bitop.luajit.org/api.html"><span class="ext">&raquo;</span>&nbsp;Lua BitOp API functions</a>.
-</p>
-<p>
-Please make sure to <tt>require</tt> the module before using any of
-its functions:
-</p>
-<pre class="code">
-local bit = require("bit")
-</pre>
-<p>
-An already installed Lua BitOp module is ignored by LuaJIT.
-This way you can use bit operations from both Lua and LuaJIT on a
-shared installation.
-</p>

-<h3 id="ffi"><tt>ffi.*</tt> &mdash; FFI library</h3>
-<p>
-The <a href="ext_ffi.html">FFI library</a> allows calling external
-C&nbsp;functions and the use of C&nbsp;data structures from pure Lua
-code.
-</p>
-
-<h3 id="jit"><tt>jit.*</tt> &mdash; JIT compiler control</h3>
-<p>
-The functions in this module
-<a href="ext_jit.html">control the behavior of the JIT compiler engine</a>.
-</p>
-
-<h3 id="c_api">C API extensions</h3>
-<p>
-LuaJIT adds some
-<a href="ext_c_api.html">extra functions to the Lua/C API</a>.
-</p>
-
-<h2 id="library">Enhanced Standard Library Functions</h2>
-
-<h3 id="xpcall"><tt>xpcall(f, err [,args...])</tt> passes arguments</h3>
-<p>
-Unlike the standard implementation in Lua 5.1, <tt>xpcall()</tt>
-passes any arguments after the error function to the function
-which is called in a protected context.
-</p>
-
-<h3 id="load"><tt>loadfile()</tt> etc. handle UTF-8 source code</h3>
-<p>
-Non-ASCII characters are handled transparently by the Lua source code parser.
-This allows the use of UTF-8 characters in identifiers and strings.
-A UTF-8 BOM is skipped at the start of the source code.
-</p>
-
-<h3 id="tostring"><tt>tostring()</tt> etc. canonicalize NaN and &plusmn;Inf</h3>
-<p>
-All number-to-string conversions consistently convert non-finite numbers
-to the same strings on all platforms. NaN results in <tt>"nan"</tt>,
-positive infinity results in <tt>"inf"</tt> and negative infinity results
-in <tt>"-inf"</tt>.
-</p>
-
-<h3 id="tonumber"><tt>tonumber()</tt> etc. use builtin string to number conversion</h3>
-<p>
-All string-to-number conversions consistently convert integer and
-floating-point inputs in decimal and hexadecimal on all platforms.
-<tt>strtod()</tt> is <em>not</em> used anymore, which avoids numerous
-problems with poor C library implementations. The builtin conversion
-function provides full precision according to the IEEE-754 standard, it
-works independently of the current locale and it supports hex floating-point
-numbers (e.g. <tt>0x1.5p-3</tt>).
-</p>
-
-<h3 id="string_dump"><tt>string.dump(f [,strip])</tt> generates portable bytecode</h3>
-<p>
-An extra argument has been added to <tt>string.dump()</tt>. If set to
-<tt>true</tt>, 'stripped' bytecode without debug information is
-generated. This speeds up later bytecode loading and reduces memory
-usage. See also the
-<a href="running.html#opt_b"><tt>-b</tt> command line option</a>.
-</p>
-<p>
-The generated bytecode is portable and can be loaded on any architecture
-that LuaJIT supports, independent of word size or endianess. However the
-bytecode compatibility versions must match. Bytecode stays compatible
-for dot releases (x.y.0 &rarr; x.y.1), but may change with major or
-minor releases (2.0 &rarr; 2.1) or between any beta release. Foreign
-bytecode (e.g. from Lua 5.1) is incompatible and cannot be loaded.
-</p>
-
-<h3 id="math_random">Enhanced PRNG for <tt>math.random()</tt></h3>
-<p>
-LuaJIT uses a Tausworthe PRNG with period 2^223 to implement
-<tt>math.random()</tt> and <tt>math.randomseed()</tt>. The quality of
-the PRNG results is much superior compared to the standard Lua
-implementation which uses the platform-specific ANSI rand().
-</p>
-<p>
-The PRNG generates the same sequences from the same seeds on all
-platforms and makes use of all bits in the seed argument.
-<tt>math.random()</tt> without arguments generates 52 pseudo-random bits
-for every call. The result is uniformly distributed between 0.0 and 1.0.
-It's correctly scaled up and rounded for <tt>math.random(n&nbsp;[,m])</tt> to
-preserve uniformity.
-</p>
-
-<h3 id="io"><tt>io.*</tt> functions handle 64&nbsp;bit file offsets</h3>
-<p>
-The file I/O functions in the standard <tt>io.*</tt> library handle
-64&nbsp;bit file offsets. In particular this means it's possible
-to open files larger than 2&nbsp;Gigabytes and to reposition or obtain
-the current file position for offsets beyond 2&nbsp;GB
-(<tt>fp:seek()</tt> method).
-</p>
-
-<h3 id="debug_meta"><tt>debug.*</tt> functions identify metamethods</h3>
-<p>
-<tt>debug.getinfo()</tt> and <tt>lua_getinfo()</tt> also return information
-about invoked metamethods. The <tt>namewhat</tt> field is set to
-<tt>"metamethod"</tt> and the <tt>name</tt> field has the name of
-the corresponding metamethod (e.g. <tt>"__index"</tt>).
-</p>
-
-<h2 id="resumable">Fully Resumable VM</h2>
-<p>
-The LuaJIT VM is fully resumable. This means you can yield from a
-coroutine even across contexts, where this would not possible with
-the standard Lua&nbsp;5.1 VM: e.g. you can yield across <tt>pcall()</tt>
-and <tt>xpcall()</tt>, across iterators and across metamethods.
-</p>
-
-<h2 id="lua52">Extensions from Lua 5.2</h2>
-<p>
-LuaJIT supports some language and library extensions from Lua&nbsp;5.2.
-Features that are unlikely to break existing code are unconditionally
-enabled:
-</p>
-<ul>
-<li><tt>goto</tt> and <tt>::labels::</tt>.</li>
-<li>Hex escapes <tt>'\x3F'</tt> and <tt>'\*'</tt> escape in strings.</li>
-<li><tt>load(string|reader, chunkname [,mode [,env]])</tt>.
-<tt>loadstring()</tt> is an alias.</li>
-<li><tt>math.log(x [,base])</tt>.
-<li><tt>string.rep(s, n [,sep])</tt>.
-<li><tt>string.format()</tt>: <tt>%q</tt> reversible.
-<tt>%s</tt> checks <tt>__tostring</tt>.
-<tt>%a</tt> and <tt>"%A</tt> added.</li>
-<li>String matching pattern <tt>%g</tt> added.</li>
-<li><tt>io.read("*L")</tt>.</li>
-<li><tt>io.lines()</tt> and <tt>file:lines()</tt> process
-<tt>io.read()</tt> options.</li>
-<li><tt>os.exit(status|true|false [,close])</tt>.</li>
-<li><tt>package.searchpath(name, path [, sep [, rep]])</tt>.</li>
-<li><tt>package.loadlib(name, "*")</tt>.</li>
-<li><tt>debug.getinfo()</tt> returns <tt>nparams</tt> and <tt>isvararg</tt>
-for option <tt>"u"</tt>.</li>
-<li><tt>debug.getlocal()</tt> accepts function instead of level.</li>
-<li><tt>debug.getlocal()</tt> and <tt>debug.setlocal()</tt> accept negative
-indexes for varargs.</li>
-<li><tt>debug.getupvalue()</tt> and <tt>debug.setupvalue()</tt> handle
-C&nbsp;functions.</li>
-<li><tt>debug.upvalueid()</tt> and <tt>debug.upvaluejoin()</tt>.</li>
-<li>Command line option <tt>-E</tt>.</li>
-<li>Command line checks <tt>__tostring</tt> for errors.</li>
-</ul>
-<p>
-Other features are only enabled, if LuaJIT is built with
-<tt>-DLUAJIT_ENABLE_LUA52COMPAT</tt>:
-</p>
-<ul>
-<li><tt>goto</tt> is a keyword and not a valid variable name anymore.</li>
-<li><tt>break</tt> can be placed anywhere. Empty statements (<tt>;;</tt>)
-are allowed.</li>
-<li><tt>__lt</tt>, <tt>__le</tt> are invoked for mixed types.</li>
-<li><tt>__len</tt> for tables. <tt>rawlen()</tt> library function.</li>
-<li><tt>pairs()</tt> and <tt>ipairs()</tt> check for <tt>__pairs</tt> and
-<tt>__ipairs</tt>.</li>
-<li><tt>coroutine.running()</tt> returns two results.</li>
-<li><tt>table.pack()</tt> and <tt>table.unpack()</tt>
-(same as <tt>unpack()</tt>).</li>
-<li><tt>io.write()</tt> and <tt>file:write()</tt> return file handle
-instead of <tt>true</tt>.</li>
-<li><tt>os.execute()</tt> and <tt>pipe:close()</tt> return detailed
-exit status.</li>
-<li><tt>debug.setmetatable()</tt> returns object.</li>
-<li><tt>debug.getuservalue()</tt> and <tt>debug.setuservalue()</tt>.</li>
-<li>Remove <tt>math.mod()</tt>, <tt>string.gfind()</tt>.
-</ul>
-<p>
-Note: this provides only partial compatibility with Lua 5.2 at the
-language and Lua library level. LuaJIT is API+ABI-compatible with
-Lua&nbsp;5.1, which prevents implementing features that would otherwise
-break the Lua/C API and ABI (e.g. <tt>_ENV</tt>).
-</p>
-
-<h2 id="exceptions">C++ Exception Interoperability</h2>
-<p>
-LuaJIT has built-in support for interoperating with C++&nbsp;exceptions.
-The available range of features depends on the target platform and
-the toolchain used to compile LuaJIT:
-</p>
-<table class="exc">
-<tr class="exchead">
-<td class="excplatform">Platform</td>
-<td class="exccompiler">Compiler</td>
-<td class="excinterop">Interoperability</td>

-</tr>
-</table>
-<p>
-<b style="color: #00a000;">Full interoperability</b> means:
-</p>
-<ul>
-<li>C++&nbsp;exceptions can be caught on the Lua side with <tt>pcall()</tt>,
-<tt>lua_pcall()</tt> etc.</li>
-<li>C++&nbsp;exceptions will be converted to the generic Lua error
-<tt>"C++&nbsp;exception"</tt>, unless you use the
-<a href="ext_c_api.html#mode_wrapcfunc">C&nbsp;call wrapper</a> feature.</li>
-<li>It's safe to throw C++&nbsp;exceptions across non-protected Lua frames
-on the C&nbsp;stack. The contents of the C++&nbsp;exception object
-pass through unmodified.</li>
-<li>Lua errors can be caught on the C++ side with <tt>catch(...)</tt>.
-The corresponding Lua error message can be retrieved from the Lua stack.</li>
-<li>Throwing Lua errors across C++ frames is safe. C++ destructors
-will be called.</li>
-</ul>
-<p>
-<b style="color: #c06000;">Limited interoperability</b> means:
-</p>
-<ul>
-<li>C++&nbsp;exceptions can be caught on the Lua side with <tt>pcall()</tt>,
-<tt>lua_pcall()</tt> etc.</li>
-<li>C++&nbsp;exceptions will be converted to the generic Lua error
-<tt>"C++&nbsp;exception"</tt>, unless you use the
-<a href="ext_c_api.html#mode_wrapcfunc">C&nbsp;call wrapper</a> feature.</li>
-<li>C++&nbsp;exceptions will be caught by non-protected Lua frames and
-are rethrown as a generic Lua error. The C++&nbsp;exception object will
-be destroyed.</li>
-<li>Lua errors <b>cannot</b> be caught on the C++ side.</li>
-<li>Throwing Lua errors across C++ frames will <b>not</b> call
-C++ destructors.</li>
-</ul>
-
-<p>
-<b style="color: #a00000;">No interoperability</b> means:
-</p>
-<ul>
-<li>It's <b>not</b> safe to throw C++&nbsp;exceptions across Lua frames.</li>
-<li>C++&nbsp;exceptions <b>cannot</b> be caught on the Lua side.</li>
-<li>Lua errors <b>cannot</b> be caught on the C++ side.</li>
-<li>Throwing Lua errors across C++ frames will <b>not</b> call
-C++ destructors.</li>
-<li>Additionally, on Windows/x86 with SEH-based C++&nbsp;exceptions:
-it's <b>not</b> safe to throw a Lua error across any frames containing
-a C++ function with any try/catch construct or using variables with
-(implicit) destructors. This also applies to any functions which may be
-inlined in such a function. It doesn't matter whether <tt>lua_error()</tt>
-is called inside or outside of a try/catch or whether any object actually
-needs to be destroyed: the SEH chain is corrupted and this will eventually
-lead to the termination of the process.</li>

-<dt>Q: Why do I get this error: "attempt to index global 'arg' (a nil value)"?<br>
-Q: My vararg functions fail after switching to LuaJIT!</dt>
-<dd>LuaJIT is compatible to the Lua 5.1 language standard. It doesn't
-support the implicit <tt>arg</tt> parameter for old-style vararg
-functions from Lua 5.0.<br>Please convert your code to the
-<a href="http://www.lua.org/manual/5.1/manual.html#2.5.9"><span class="ext">&raquo;</span>&nbsp;Lua 5.1
-vararg syntax</a>.</dd>
-</dl>
-
-<dl>
-<dt>Q: Why do I get this error: "bad FPU precision"?<br>
-<dt>Q: I get weird behavior after initializing Direct3D.<br>
-<dt>Q: Some FPU operations crash after I load a Delphi DLL.<br>
-</dt>
-<dd>
-
-DirectX/Direct3D (up to version 9) sets the x87 FPU to single-precision
-mode by default. This violates the Windows ABI and interferes with the
-operation of many programs &mdash; LuaJIT is affected, too. Please make
-sure you always use the <tt>D3DCREATE_FPU_PRESERVE</tt> flag when
-initializing Direct3D.<br>
-
-Direct3D version 10 or higher do not show this behavior anymore.
-Consider testing your application with older versions, too.<br>
-
-Similarly, the Borland/Delphi runtime modifies the FPU control word and
-enables FP exceptions. Of course this violates the Windows ABI, too.
-Please check the Delphi docs for the Set8087CW method.
-
-</dl>
-
-<dl>
-<dt>Q: Sometimes Ctrl-C fails to stop my Lua program. Why?</dt>
-<dd>The interrupt signal handler sets a Lua debug hook. But this is
-currently ignored by compiled code (this will eventually be fixed). If
-your program is running in a tight loop and never falls back to the
-interpreter, the debug hook never runs and can't throw the
-"interrupted!" error.<br> In the meantime you have to press Ctrl-C
-twice to get stop your program. That's similar to when it's stuck
-running inside a C function under the Lua interpreter.</dd>
-</dl>
-
-<dl>
-<dt>Q: Why doesn't my favorite power-patch for Lua apply against LuaJIT?</dt>
-<dd>Because it's a completely redesigned VM and has very little code
-in common with Lua anymore. Also, if the patch introduces changes to
-the Lua semantics, these would need to be reflected everywhere in the
-VM, from the interpreter up to all stages of the compiler.<br> Please
-use only standard Lua language constructs. For many common needs you
-can use source transformations or use wrapper or proxy functions.
-The compiler will happily optimize away such indirections.</dd>
-</dl>
-
-<dl>
-<dt>Q: Lua runs everywhere. Why doesn't LuaJIT support my CPU?</dt>
-<dd>Because it's a compiler &mdash; it needs to generate native
-machine code. This means the code generator must be ported to each
-architecture. And the fast interpreter is written in assembler and
-must be ported, too. This is quite an undertaking.<br>
-The <a href="install.html">install documentation</a> shows the supported
-architectures. Other architectures will follow based on sufficient user
-demand and/or sponsoring.</dd>
-</dl>
-
-<dl>
-<dt>Q: When will feature X be added? When will the next version be released?</dt>
-<dd>When it's ready.<br>
-C'mon, it's open source &mdash; I'm doing it on my own time and you're
-getting it for free. You can either contribute a patch or sponsor
-the development of certain features, if they are important to you.

-LuaJIT is only distributed as a source package. This page explains
-how to build and install LuaJIT with different operating systems
-and C&nbsp;compilers.
-</p>
-<p>
-For the impatient (on POSIX systems):
-</p>
-<pre class="code">

-<p>
-LuaJIT currently builds out-of-the box on most systems.

-<h2>Configuring LuaJIT</h2>
-<p>
-The standard configuration should work fine for most installations.
-Usually there is no need to tweak the settings. The following files
-hold all user-configurable settings:
-</p>
-<ul>
-<li><tt>src/luaconf.h</tt> sets some configuration variables.</li>
-<li><tt>Makefile</tt> has settings for <b>installing</b> LuaJIT (POSIX
-only).</li>
-<li><tt>src/Makefile</tt> has settings for <b>compiling</b> LuaJIT
-under POSIX, MinGW or Cygwin.</li>
-<li><tt>src/msvcbuild.bat</tt> has settings for compiling LuaJIT with
-MSVC or WinSDK.</li>
-</ul>
-<p>
-Please read the instructions given in these files, before changing
-any settings.
-</p>
-
-<h2 id="posix">POSIX Systems (Linux, OSX, *BSD etc.)</h2>
-<h3>Prerequisites</h3>
-<p>
-Depending on your distribution, you may need to install a package for
-GCC, the development headers and/or a complete SDK. E.g. on a current
-Debian/Ubuntu, install <tt>libc6-dev</tt> with the package manager.
-</p>
-<p>
-Download the current source package of LuaJIT (pick the .tar.gz),
-if you haven't already done so. Move it to a directory of your choice,
-open a terminal window and change to this directory. Now unpack the archive
-and change to the newly created directory:
-</p>
-<pre class="code">
-tar zxf LuaJIT-2.0.1.tar.gz
-cd LuaJIT-2.0.1</pre>
-<h3>Building LuaJIT</h3>
-<p>
-The supplied Makefiles try to auto-detect the settings needed for your
-operating system and your compiler. They need to be run with GNU Make,
-which is probably the default on your system, anyway. Simply run:
-</p>
-<pre class="code">
-make
-</pre>
-<p>
-This always builds a native x86, x64 or PPC binary, depending on the host OS
-you're running this command on. Check the section on
-<a href="#cross">cross-compilation</a> for more options.
-</p>
-<p>
-By default, modules are only searched under the prefix <tt>/usr/local</tt>.
-You can add an extra prefix to the search paths by appending the
-<tt>PREFIX</tt> option, e.g.:
-</p>
-<pre class="code">
-make PREFIX=/home/myself/lj2
-</pre>
-<p>
-Note for OSX: if the <tt>MACOSX_DEPLOYMENT_TARGET</tt> environment
-variable is not set, then it's forced to <tt>10.4</tt>.
-</p>
-<h3>Installing LuaJIT</h3>
-<p>
-The top-level Makefile installs LuaJIT by default under
-<tt>/usr/local</tt>, i.e. the executable ends up in
-<tt>/usr/local/bin</tt> and so on. You need root privileges
-to write to this path. So, assuming sudo is installed on your system,
-run the following command and enter your sudo password:
-</p>
-<pre class="code">
-sudo make install
-</pre>
-<p>
-Otherwise specify the directory prefix as an absolute path, e.g.:
-</p>
-<pre class="code">
-make install PREFIX=/home/myself/lj2
-</pre>
-<p>
-Obviously the prefixes given during build and installation need to be the same.
-</p>
-
-<h2 id="windows">Windows Systems</h2>
-<h3>Prerequisites</h3>
-<p>
-Either install one of the open source SDKs
-(<a href="http://mingw.org/"><span class="ext">&raquo;</span>&nbsp;MinGW</a> or
-<a href="http://www.cygwin.com/"><span class="ext">&raquo;</span>&nbsp;Cygwin</a>), which come with a modified
-GCC plus the required development headers.
-</p>
-<p>
-Or install Microsoft's Visual C++ (MSVC). The freely downloadable
-<a href="http://www.microsoft.com/Express/VC/"><span class="ext">&raquo;</span>&nbsp;Express Edition</a>
-works just fine, but only contains an x86 compiler.
-</p>
-<p>
-The freely downloadable
-<a href="http://msdn.microsoft.com/en-us/windowsserver/bb980924.aspx"><span class="ext">&raquo;</span>&nbsp;Windows SDK</a>
-only comes with command line tools, but this is all you need to build LuaJIT.
-It contains x86 and x64 compilers.
-</p>
-<p>
-Next, download the source package and unpack it using an archive manager
-(e.g. the Windows Explorer) to a directory of your choice.
-</p>
-<h3>Building with MSVC</h3>
-<p>
-Open a "Visual Studio .NET Command Prompt", <tt>cd</tt> to the
-directory where you've unpacked the sources and run these commands:
-</p>
-<pre class="code">
-cd src
-msvcbuild
-</pre>
-<p>
-Then follow the installation instructions below.
-</p>
-<h3>Building with the Windows SDK</h3>
-<p>
-Open a "Windows SDK Command Shell" and select the x86 compiler:
-</p>
-<pre class="code">
-setenv /release /x86
-</pre>
-<p>
-Or select the x64 compiler:
-</p>
-<pre class="code">
-setenv /release /x64
-</pre>
-<p>
-Then <tt>cd</tt> to the directory where you've unpacked the sources
-and run these commands:
-</p>
-<pre class="code">
-cd src
-msvcbuild
-</pre>
-<p>
-Then follow the installation instructions below.
-</p>
-<h3>Building with MinGW or Cygwin</h3>
-<p>
-Open a command prompt window and make sure the MinGW or Cygwin programs
-are in your path. Then <tt>cd</tt> to the directory where
-you've unpacked the sources and run this command for MinGW:
-</p>
-<pre class="code">
-mingw32-make
-</pre>
-<p>
-Or this command for Cygwin:
-</p>
-<pre class="code">
-make
-</pre>
-<p>
-Then follow the installation instructions below.
-</p>
-<h3>Installing LuaJIT</h3>
-<p>
-Copy <tt>luajit.exe</tt> and <tt>lua51.dll</tt> (built in the <tt>src</tt>
-directory) to a newly created directory (any location is ok).
-Add <tt>lua</tt> and <tt>lua\jit</tt> directories below it and copy
-all Lua files from the <tt>src\jit</tt> directory of the distribution
-to the latter directory.
-</p>
-<p>
-There are no hardcoded
-absolute path names &mdash; all modules are loaded relative to the
-directory where <tt>luajit.exe</tt> is installed
-(see <tt>src/luaconf.h</tt>).
-</p>
-
-<h2 id="cross">Cross-compiling LuaJIT</h2>
-<p>
-The GNU Makefile-based build system allows cross-compiling on any host
-for any supported target, as long as both architectures have the same
-pointer size. If you want to cross-compile to any 32 bit target on an
-x64 OS, you need to install the multilib development package (e.g.
-<tt>libc6-dev-i386</tt> on Debian/Ubuntu) and build a 32 bit host part
-(<tt>HOST_CC="gcc -m32"</tt>).
-</p>
-<p>
-You need to specify <tt>TARGET_SYS</tt> whenever the host OS and the
-target OS differ, or you'll get assembler or linker errors. E.g. if
-you're compiling on a Windows or OSX host for embedded Linux or Android,
-you need to add <tt>TARGET_SYS=Linux</tt> to the examples below. For a
-minimal target OS, you may need to disable the built-in allocator in
-<tt>src/Makefile</tt> and use <tt>TARGET_SYS=Other</tt>. The examples
-below only show some popular targets &mdash; please check the comments
-in <tt>src/Makefile</tt> for more details.
-</p>
-<pre class="code">
-# Cross-compile to a 32 bit binary on a multilib x64 OS
-make CC="gcc -m32"
-
-# Cross-compile on Debian/Ubuntu for Windows (mingw32 package)
-make HOST_CC="gcc -m32" CROSS=i586-mingw32msvc- TARGET_SYS=Windows
-</pre>
-<p id="cross2">
-The <tt>CROSS</tt> prefix allows specifying a standard GNU cross-compile
-toolchain (Binutils, GCC and a matching libc). The prefix may vary
-depending on the <tt>--target</tt> the toolchain was built for (note the
-<tt>CROSS</tt> prefix has a trailing <tt>"-"</tt>). The examples below
-use the canonical toolchain triplets for Linux.
-</p>
-<p>
-Since there's often no easy way to detect CPU features at runtime, it's
-important to compile with the proper CPU or architecture settings. You
-can specify these when building the toolchain yourself. Or add
-<tt>-mcpu=...</tt> or <tt>-march=...</tt> to <tt>TARGET_CFLAGS</tt>. For
-ARM it's important to have the correct <tt>-mfloat-abi=...</tt> setting,
-too. Otherwise LuaJIT may not run at the full performance of your target
-CPU.
-</p>
-<pre class="code">
-# ARM soft-float
-make HOST_CC="gcc -m32" CROSS=arm-linux-gnueabi- \
-     TARGET_CFLAGS="-mfloat-abi=soft"
-
-# ARM soft-float ABI with VFP (example for Cortex-A8)
-make HOST_CC="gcc -m32" CROSS=arm-linux-gnueabi- \
-     TARGET_CFLAGS="-mcpu=cortex-a8 -mfloat-abi=softfp"
-
-# ARM hard-float ABI with VFP (armhf, requires recent toolchain)
-make HOST_CC="gcc -m32" CROSS=arm-linux-gnueabihf-
-
-# PPC
-make HOST_CC="gcc -m32" CROSS=powerpc-linux-gnu-
-# PPC/e500v2 (fast interpreter only)
-make HOST_CC="gcc -m32" CROSS=powerpc-e500v2-linux-gnuspe-
-
-# MIPS big-endian
-make HOST_CC="gcc -m32" CROSS=mips-linux-
-# MIPS little-endian
-make HOST_CC="gcc -m32" CROSS=mipsel-linux-
-</pre>
-<p>
-You can cross-compile for <b id="android">Android</b> using the <a href="http://developer.android.com/sdk/ndk/index.html"><span class="ext">&raquo;</span>&nbsp;Android NDK</a>.
-The environment variables need to match the install locations and the
-desired target platform. E.g. Android&nbsp;4.0 corresponds to ABI level&nbsp;14.
-For details check the folder <tt>docs</tt> in the NDK directory.
-</p>
-<p>
-Only a few common variations for the different CPUs, ABIs and platforms
-are listed. Please use your own judgement for which combination you want
-to build/deploy or which lowest common denominator you want to pick:

-You can cross-compile for <b id="ios">iOS 3.0+</b> (iPhone/iPad) using the <a href="http://developer.apple.com/devcenter/ios/index.action"><span class="ext">&raquo;</span>&nbsp;iOS SDK</a>.
-The environment variables need to match the iOS SDK version:
-</p>
-<p style="font-size: 8pt;">
-Note: <b>the JIT compiler is disabled for iOS</b>, because regular iOS Apps
-are not allowed to generate code at runtime. You'll only get the performance
-of the LuaJIT interpreter on iOS. This is still faster than plain Lua, but
-much slower than the JIT compiler. Please complain to Apple, not me.
-Or use Android. :-p
-</p>
-<pre class="code">

-make HOST_CC="gcc -m32 -arch i386" CROSS=$ISDKP TARGET_FLAGS="$ISDKF" \
-     TARGET_SYS=iOS
-</pre>
-<p>
-You can cross-compile for <b id="ps3">PS3</b> using the PS3&nbsp;SDK from
-a Linux host or a Windows host (requires 32 bit MinGW (GCC) on the host,
-too). Due to restrictions on consoles, the JIT compiler is disabled and
-only the fast interpreter is built:
-</p>
-<pre class="code">
-make HOST_CC="gcc -m32" CROSS=ppu-lv2-
-</pre>
-<p>
-You can cross-compile for <b id="xbox360">Xbox 360</b> using the
-Xbox&nbsp;360 SDK (MSVC + XEDK). Due to restrictions on consoles, the
-JIT compiler is disabled and only the fast interpreter is built.
-</p>
-<p>
-Open a "Visual Studio .NET Command Prompt" (32&nbsp;bit host compiler),
-<tt>cd</tt> to the directory where you've unpacked the sources and run
-the following commands. This builds a static library <tt>luajit20.lib</tt>,
-which can be linked against your game, just like the Lua library.
-</p>
-<pre class="code">
-cd src
-xedkbuild
-</pre>
-
-<h2 id="embed">Embedding LuaJIT</h2>
-<p>
-LuaJIT is API-compatible with Lua 5.1. If you've already embedded Lua
-into your application, you probably don't need to do anything to switch
-to LuaJIT, except link with a different library:
-</p>
-<ul>
-<li>It's strongly suggested to build LuaJIT separately using the supplied
-build system. Please do <em>not</em> attempt to integrate the individual
-source files into your build tree. You'll most likely get the internal build
-dependencies wrong or mess up the compiler flags. Treat LuaJIT like any
-other external library and link your application with either the dynamic
-or static library, depending on your needs.</li>
-<li>If you want to load C modules compiled for plain Lua
-with <tt>require()</tt>, you need to make sure the public symbols
-(e.g. <tt>lua_pushnumber</tt>) are exported, too:
-<ul><li>On POSIX systems you can either link to the shared library
-or link the static library into your application. In the latter case
-you'll need to export all public symbols from your main executable
-(e.g. <tt>-Wl,-E</tt> on Linux) and add the external dependencies
-(e.g. <tt>-lm -ldl</tt> on Linux).</li>
-<li>Since Windows symbols are bound to a specific DLL name, you need to
-link to the <tt>lua51.dll</tt> created by the LuaJIT build (do not rename
-the DLL). You may link LuaJIT statically on Windows only if you don't
-intend to load Lua/C modules at runtime.
-</li></ul>
-</li>
-<li>
-If you're building a 64 bit application on OSX which links directly or
-indirectly against LuaJIT, you need to link your main executable
-with these flags:
-<pre class="code">
--pagezero_size 10000 -image_base 100000000
-</pre>
-Also, it's recommended to <tt>rebase</tt> all (self-compiled) shared libraries
-which are loaded at runtime on OSX/x64 (e.g. C extension modules for Lua).
-See: <tt>man rebase</tt>
-</li>
-</ul>
-<p>Additional hints for initializing LuaJIT using the C API functions:</p>
-<ul>
-<li>Here's a
-<a href="http://lua-users.org/wiki/SimpleLuaApiExample"><span class="ext">&raquo;</span>&nbsp;simple example</a>
-for embedding Lua or LuaJIT into your application.</li>
-<li>Make sure you use <tt>luaL_newstate</tt>. Avoid using
-<tt>lua_newstate</tt>, since this uses the (slower) default memory
-allocator from your system (no support for this on x64).</li>
-<li>Make sure you use <tt>luaL_openlibs</tt> and not the old Lua 5.0 style
-of calling <tt>luaopen_base</tt> etc. directly.</li>
-<li>To change or extend the list of standard libraries to load, copy
-<tt>src/lib_init.c</tt> to your project and modify it accordingly.
-Make sure the <tt>jit</tt> library is loaded or the JIT compiler
-will not be activated.</li>
-<li>The <tt>bit.*</tt> module for bitwise operations
-is already built-in. There's no need to statically link
-<a href="http://bitop.luajit.org/"><span class="ext">&raquo;</span>&nbsp;Lua BitOp</a> to your application.</li>
-</ul>
-
-<h2 id="distro">Hints for Distribution Maintainers</h2>
-<p>
-The LuaJIT build system has extra provisions for the needs of most
-POSIX-based distributions. If you're a package maintainer for
-a distribution, <em>please</em> make use of these features and
-avoid patching, subverting, autotoolizing or messing up the build system
-in unspeakable ways.
-</p>
-<p>
-There should be absolutely no need to patch <tt>luaconf.h</tt> or any
-of the Makefiles. And please do not hand-pick files for your packages &mdash;
-simply use whatever <tt>make install</tt> creates. There's a reason
-for all of the files <em>and</em> directories it creates.
-</p>
-<p>
-The build system uses GNU make and auto-detects most settings based on
-the host you're building it on. This should work fine for native builds,
-even when sandboxed. You may need to pass some of the following flags to
-<em>both</em> the <tt>make</tt> and the <tt>make install</tt> command lines
-for a regular distribution build:
-</p>
-<ul>
-<li><tt>PREFIX</tt> overrides the installation path and should usually
-be set to <tt>/usr</tt>. Setting this also changes the module paths and
-the <tt>-rpath</tt> of the shared library.</li>
-<li><tt>DESTDIR</tt> is an absolute path which allows you to install
-to a shadow tree instead of the root tree of the build system.</li>
-<li>Have a look at the top-level <tt>Makefile</tt> and <tt>src/Makefile</tt>
-for additional variables to tweak. The following variables <em>may</em> be
-overridden, but it's <em>not</em> recommended, except for special needs
-like cross-builds:
-<tt>BUILDMODE, CC, HOST_CC, STATIC_CC, DYNAMIC_CC, CFLAGS, HOST_CFLAGS,
-TARGET_CFLAGS, LDFLAGS, HOST_LDFLAGS, TARGET_LDFLAGS, TARGET_SHLDFLAGS,
-TARGET_FLAGS, LIBS, HOST_LIBS, TARGET_LIBS, CROSS, HOST_SYS, TARGET_SYS
-</tt></li>
-</ul>
-<p>
-The build system has a special target for an amalgamated build, i.e.
-<tt>make amalg</tt>. This compiles the LuaJIT core as one huge C file
-and allows GCC to generate faster and shorter code. Alas, this requires
-lots of memory during the build. This may be a problem for some users,
-that's why it's not enabled by default. But it shouldn't be a problem for
-most build farms. It's recommended that binary distributions use this
-target for their LuaJIT builds.
-</p>
-<p>
-The tl;dr version of the above:
-</p>
-<pre class="code">
-make amalg PREFIX=/usr && \
-make install PREFIX=/usr DESTDIR=/tmp/buildroot
-</pre>
-<p>
-Finally, if you encounter any difficulties, please
-<a href="contact.html">contact me</a> first, instead of releasing a broken
-package onto unsuspecting users. Because they'll usually gonna complain
-to me (the upstream) and not you (the package maintainer), anyway.

-LuaJIT has been successfully used as a <b>scripting middleware</b> in
-games, appliances, network and graphics apps, numerical simulations,
-trading platforms and many other specialty applications. It scales from
-embedded devices, smartphones, desktops up to server farms. It combines
-high flexibility with <a href="http://luajit.org/performance.html"><span class="ext">&raquo;</span>&nbsp;high performance</a>
-and an unmatched <b>low memory footprint</b>.
-</p>
-<p>
-LuaJIT has been in continuous development since 2005. It's widely
-considered to be <b>one of the fastest dynamic language
-implementations</b>. It has outperformed other dynamic languages on many
-cross-language benchmarks since its first release &mdash; often by a
-substantial margin.
-</p>
-<p>
-For <b>LuaJIT 2.0</b>, the whole VM has been rewritten from the ground up
-and relentlessly optimized for performance. It combines a <b>high-speed
-interpreter</b>, written in assembler, with a <b>state-of-the-art JIT
-compiler</b>.
-</p>
-<p>
-An innovative <b>trace compiler</b> is integrated with advanced,
-SSA-based optimizations and highly tuned code generation backends.
-A substantial reduction of the overhead associated with dynamic languages
-allows it to break into the performance range traditionally reserved for
-offline, static language compilers.

-<span style="color: #0000c0;">LuaJIT&nbsp;2.0</span> is the current
-<span style="color: #0000c0;">stable branch</span>. This branch is in
-feature-freeze &mdash; new features will only be added to LuaJIT&nbsp;2.1.
-</p>
-
-<h2>Current Status</h2>
-<p>
-LuaJIT ought to run all Lua&nbsp;5.1-compatible source code just fine.
-It's considered a serious bug if the VM crashes or produces unexpected
-results &mdash; please report this.
-</p>
-<p>
-Known incompatibilities and issues in LuaJIT&nbsp;2.0:
-</p>
-<ul>
-<li>
-There are some differences in <b>implementation-defined</b> behavior.
-These either have a good reason, are arbitrary design choices
-or are due to quirks in the VM. The latter cases may get fixed if a
-demonstrable need is shown.
-</li>
-<li>
-The Lua <b>debug API</b> is missing a couple of features (return
-hooks for non-Lua functions) and shows slightly different behavior
-in LuaJIT (no per-coroutine hooks, no tail call counting).
-</li>
-<li>
-Some checks are missing in the JIT-compiled code for obscure situations
-with <b>open upvalues aliasing</b> one of the SSA slots later on (or
-vice versa). Bonus points, if you can find a real world test case for
-this.
-</li>
-<li>
-Currently some <b>out-of-memory</b> errors from <b>on-trace code</b> are not
-handled correctly. The error may fall through an on-trace
-<tt>pcall</tt> or it may be passed on to the function set with
-<tt>lua_atpanic</tt> on x64. This issue will be fixed with the new
-garbage collector.
-</li>
-</ul>

-##############################################################################
-# These options mainly affect the speed of the JIT compiler itself, not the

-# Use this if you want to force a 32 bit build on a 64 bit multilib OS.
-#CC= gcc -m32
-#
-# Since the assembler part does NOT maintain a frame pointer, it's pointless
-# to slow down the C part by not omitting it. Debugging, tracebacks and
-# unwinding are not affected -- the assembler part has frame unwind
-# information and GCC emits it where needed (x64) or with -g (see CCDEBUG).
-CCOPT= -O2 -fomit-frame-pointer
-# Use this if you want to generate a smaller binary (but it's slower):
-#CCOPT= -Os -fomit-frame-pointer
-# Note: it's no longer recommended to use -O3 with GCC 4.x.
-# The I-Cache bloat usually outweighs the benefits from aggressive inlining.
-#
-# Target-specific compiler options:
-#
-# x86 only: it's recommended to compile at least for i686. Better yet,
-# compile for an architecture that has SSE2, too (-msse -msse2).
-#
-# x86/x64 only: For GCC 4.2 or higher and if you don't intend to distribute
-# the binaries to a different machine you could also use: -march=native

--- Released under the MIT license. See Copyright Notice in luajit.h
-----------------------------------------------------------------------------
---
--- This module lists the bytecode of a Lua function. If it's loaded by -jbc
--- it hooks into the parser and lists all functions of a chunk as they
--- are parsed.
---
--- Example usage:
---
---   luajit -jbc -e 'local x=0; for i=1,1e6 do x=x+i end; print(x)'
---   luajit -jbc=- foo.lua
---   luajit -jbc=foo.list foo.lua
---
--- Default output is to stderr. To redirect the output to a file, pass a
--- filename as an argument (use '-' for stdout) or set the environment
--- variable LUAJIT_LISTFILE. The file is overwritten every time the module
--- is started.
---
--- This module can also be used programmatically:
---
---   local bc = require("jit.bc")
---
---   local function foo() print("hello") end
---
---   bc.dump(foo)           --> -- BYTECODE -- [...]

--- Released under the MIT license. See Copyright Notice in luajit.h
-----------------------------------------------------------------------------
--- This is a helper module used by the LuaJIT machine code dumper module.
---
--- Sending small code snippets to an external disassembler and mixing the
--- output with our own stuff was too fragile. So I had to bite the bullet
--- and write yet another x86 disassembler. Oh well ...
---
--- The output format is very similar to what ndisasm generates. But it has
--- been developed independently by looking at the opcode tables from the
--- Intel and AMD manuals. The supported instruction set is quite extensive
--- and reflects what a current generation Intel or AMD CPU implements in
--- 32 bit and 64 bit mode. Yes, this includes MMX, SSE, SSE2, SSE3, SSSE3,
--- SSE4.1, SSE4.2, SSE4a and even privileged and hypervisor (VMX/SVM)
--- instructions.
---
--- Notes:
--- * The (useless) a16 prefix, 3DNow and pre-586 opcodes are unsupported.
--- * No attempt at optimization has been made -- it's fast enough for my needs.
--- * The public API may change when more architectures are added.

--- LuaJIT compiler dump module.
---
--- Copyright (C) 2005-2013 Mike Pall. All rights reserved.
--- Released under the MIT license. See Copyright Notice in luajit.h
-----------------------------------------------------------------------------
---
--- This module can be used to debug the JIT compiler itself. It dumps the
--- code representations and structures used in various compiler stages.
---
--- Example usage:
---
---   luajit -jdump -e "local x=0; for i=1,1e6 do x=x+i end; print(x)"
---   luajit -jdump=im -e "for i=1,1000 do for j=1,1000 do end end" | less -R
---   luajit -jdump=is myapp.lua | less -R
---   luajit -jdump=-b myapp.lua
---   luajit -jdump=+aH,myapp.html myapp.lua
---   luajit -jdump=ixT,myapp.dump myapp.lua
---
--- The first argument specifies the dump mode. The second argument gives
--- the output file name. Default output is to stdout, unless the environment
--- variable LUAJIT_DUMPFILE is set. The file is overwritten every time the
--- module is started.
---
--- Different features can be turned on or off with the dump mode. If the
--- mode starts with a '+', the following features are added to the default
--- set of features; a '-' removes them. Otherwise the features are replaced.
---
--- The following dump features are available (* marks the default):
---
---  * t  Print a line for each started, ended or aborted trace (see also -jv).
---  * b  Dump the traced bytecode.
---  * i  Dump the IR (intermediate representation).
---    r  Augment the IR with register/stack slots.
---    s  Dump the snapshot map.
---  * m  Dump the generated machine code.
---    x  Print each taken trace exit.
---    X  Print each taken trace exit and the contents of all registers.
---
--- The output format can be set with the following characters:
---
---    T  Plain text output.
---    A  ANSI-colored text output
---    H  Colorized HTML + CSS output.
---
--- The default output format is plain text. It's set to ANSI-colored text
--- if the COLORTERM variable is set. Note: this is independent of any output
--- redirection, which is actually considered a feature.
---
--- You probably want to use less -R to enjoy viewing ANSI-colored text from
--- a pipe or a file. Add this to your ~/.bashrc: export LESS="-R"

-----------------------------------------------------------------------------
---
--- This module shows verbose information about the progress of the
--- JIT compiler. It prints one line for each generated trace. This module
--- is useful to see which code has been compiled or where the compiler
--- punts and falls back to the interpreter.
---
--- Example usage:
---
---   luajit -jv -e "for i=1,1000 do for j=1,1000 do end end"
---   luajit -jv=myapp.out myapp.lua
---
--- Default output is to stderr. To redirect the output to a file, pass a
--- filename as an argument (use '-' for stdout) or set the environment
--- variable LUAJIT_VERBOSEFILE. The file is overwritten every time the
--- module is started.
---
--- The output from the first example should look like this:
---
--- [TRACE   1 (command line):1 loop]
--- [TRACE   2 (1/3) (command line):1 -> 1]
---
--- The first number in each line is the internal trace number. Next are
--- the file name ('(command line)') and the line number (':1') where the
--- trace has started. Side traces also show the parent trace number and
--- the exit number where they are attached to in parentheses ('(1/3)').
--- An arrow at the end shows where the trace links to ('-> 1'), unless
--- it loops to itself.
---
--- In this case the inner loop gets hot and is traced first, generating
--- a root trace. Then the last exit from the 1st trace gets hot, too,
--- and triggers generation of the 2nd trace. The side trace follows the
--- path along the outer loop and *around* the inner loop, back to its
--- start, and then links to the 1st trace. Yes, this may seem unusual,
--- if you know how traditional compilers work. Trace compilers are full
--- of surprises like this -- have fun! :-)
---
--- Aborted traces are shown like this:
---
--- [TRACE --- foo.lua:44 -- leaving loop in root trace at foo:lua:50]
---
--- Don't worry -- trace aborts are quite common, even in programs which
--- can be fully compiled. The compiler may retry several times until it
--- finds a suitable trace.
---
--- Of course this doesn't work with features that are not-yet-implemented
--- (NYI error messages). The VM simply falls back to the interpreter. This
--- may not matter at all if the particular trace is not very high up in
--- the CPU usage profile. Oh, and the interpreter is quite fast, too.
---
--- Also check out the -jdump module, which prints all the gory details.

-** LuaJIT can either use internal or external frame unwinding:
-**
-** - Internal frame unwinding (INT) is free-standing and doesn't require
-**   any OS or library support.
-**
-** - External frame unwinding (EXT) uses the system-provided unwind handler.
-**
-** Pros and Cons:
-**
-** - EXT requires unwind tables for *all* functions on the C stack between
-**   the pcall/catch and the error/throw. This is the default on x64,
-**   but needs to be manually enabled on x86/PPC for non-C++ code.
-**
-** - INT is faster when actually throwing errors (but this happens rarely).
-**   Setting up error handlers is zero-cost in any case.
-**
-** - EXT provides full interoperability with C++ exceptions. You can throw
-**   Lua errors or C++ exceptions through a mix of Lua frames and C++ frames.
-**   C++ destructors are called as needed. C++ exceptions caught by pcall
-**   are converted to the string "C++ exception". Lua errors can be caught
-**   with catch (...) in C++.
-**
-** - INT has only limited support for automatically catching C++ exceptions
-**   on POSIX systems using DWARF2 stack unwinding. Other systems may use
-**   the wrapper function feature. Lua errors thrown through C++ frames
-**   cannot be caught by C++ code and C++ destructors are not run.
-**
-** EXT is the default on x64 systems, INT is the default on all other systems.
-**
-** EXT can be manually enabled on POSIX systems using GCC and DWARF2 stack
-** unwinding with -DLUAJIT_UNWIND_EXTERNAL. *All* C code must be compiled
-** with -funwind-tables (or -fexceptions). This includes LuaJIT itself (set
-** TARGET_CFLAGS), all of your C/Lua binding code, all loadable C modules
-** and all C libraries that have callbacks which may be used to call back
-** into Lua. C++ code must *not* be compiled with -fno-exceptions.
-**
-** EXT cannot be enabled on WIN32 since system exceptions use code-driven SEH.
-** EXT is mandatory on WIN64 since the calling convention has an abundance
-** of callee-saved registers (rbx, rbp, rsi, rdi, r12-r15, xmm6-xmm15).
-** EXT is mandatory on POSIX/x64 since the interpreter doesn't save r12/r13.

-** valid and type-specialized references. J->base[J->maxslot] is set to 0
-** as a sentinel. The runtime argument values start at rd->argv[0].
-**
-** In general fast functions should check for presence of all of their
-** arguments and for the correct argument types. Some simplifications
-** are allowed if the interpreter throws instead. But even if recording
-** is aborted, the generated IR must be consistent (no zero-refs).
-**
-** The number of results in rd->nres is set to 1. Handlers that return
-** a different number of results need to override it. A negative value
-** prevents return processing (e.g. for pending calls).
-**
-** Results need to be stored starting at J->base[0]. Return processing
-** moves them to the right slots later.
-**
-** The per-ffid auxiliary data is the value of the 2nd part of the
-** LJLIB_REC() annotation. This allows handling similar functionality
-** in a common handler.

-**
-** Calls to metamethods store their arguments beyond the current top
-** without checking for the stack limit. This avoids stack resizes which
-** would invalidate passed TValue pointers. The stack check is performed
-** later by the function header. This can safely resize the stack or raise
-** an error. Thus we need some extra slots beyond the current stack limit.
-**
-** Most metamethods need 4 slots above top (cont, mobj, arg1, arg2) plus
-** one extra slot if mobj is not a function. Only lj_meta_tset needs 5
-** slots above top, but then mobj is always a function. So we can get by
-** with 5 extra slots.
