-<dl id="arg">
-<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="https://www.lua.org/manual/5.1/manual.html#2.5.9"><span class="ext">&raquo;</span>&nbsp;Lua 5.1
-vararg syntax</a>.</dd>

-<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.</dd>
-</dl>
-
-<dl id="ctrlc">
-<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
-ignored by compiled code. 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>
-You have to press Ctrl-C twice to stop your program. That's similar
-to when it's stuck running inside a C function under the Lua interpreter.</dd>
-</dl>
-
-<dl id="order">
-<dt>Q: Table iteration with <tt>pairs()</tt> does not result in the same order?</dt>
-<dd>The order of table iteration is explicitly <b>undefined</b> by
-the Lua language standard.<br>
-Different Lua implementations or versions may use different orders for
-otherwise identical tables. Different ways of constructing a table may
-result in different orders, too.<br>
-Due to improved VM security, LuaJIT 2.1 may even use a different order
-on separate VM invocations or when string keys are newly interned.<br><br>
-If your program relies on a deterministic order, it has a bug. Rewrite it,
-so it doesn't rely on the key order. Or sort the table keys, if you must.</dd>
-</dl>
-
-<dl id="sandbox">
-<dt>Q: Can Lua code be safely sandboxed?</dt>
-<dd>
-Maybe for an extremely restricted subset of Lua and if you relentlessly
-scrutinize every single interface function you offer to the untrusted code.<br>
-
-Although Lua provides some sandboxing functionality (<tt>setfenv()</tt>, hooks),
-it's very hard to get this right even for the Lua core libraries. Of course,
-you'll need to inspect any extension library, too. And there are libraries
-that are inherently unsafe, e.g. the <a href="ext_ffi.html">FFI library</a>.<br>
-
-More reading material at the <a href="http://lua-users.org/wiki/SandBoxes"><span class="ext">&raquo;</span>&nbsp;Lua Wiki</a> and <a href="https://en.wikipedia.org/wiki/Sandbox_(computer_security)"><span class="ext">&raquo;</span>&nbsp;Wikipedia</a>.<br><br>
-
-Relatedly, <b>loading untrusted bytecode is not safe!</b><br>
-
-It's trivial to crash the Lua or LuaJIT VM with maliciously crafted bytecode.
-This is well known and there's no bytecode verification on purpose, so please
-don't report a bug about it. Check the <tt>mode</tt> parameter for the
-<tt>load*()</tt> functions to disable loading of bytecode.<br><br>
-
-<b>In general, the only promising approach is to sandbox Lua code at the
-process level and not the VM level.</b>
-</dd>
-</dl>
-
-<dl id="arch">
-<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.<br>
-Other architectures may follow based on sufficient user demand and
-market-relevance of the architecture. Sponsoring is required to develop
-the port itself, to integrate it and to continuously maintain it in the
-actively developed branches.</dd>

-This documentation is for LuaJIT 2.1.0-beta3. Please check the <tt>doc</tt>
-directory in each git branch for the version-specific documentation.
-</p>
-<p>
-The currently developed branches are LuaJIT&nbsp;2.1 and LuaJIT&nbsp;2.0.
-</p>
-<p>
-LuaJIT&nbsp;2.0 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).
