<div>
<p>These intrinsic functions expand the "universal IR" of LLVM to represent
hardware constructs for atomic operations and memory synchronization. This
provides an interface to the hardware, not an interface to the programmer. It
is aimed at a low enough level to allow any programming models or APIs
(Application Programming Interfaces) which need atomic behaviors to map
cleanly onto it. It is also modeled primarily on hardware behavior. Just as
hardware provides a "universal IR" for source languages, it also provides a
starting point for developing a "universal" atomic operation and
synchronization IR.</p>
<p>These do <em>not</em> form an API such as high-level threading libraries,
software transaction memory systems, atomic primitives, and intrinsic
functions as found in BSD, GNU libc, atomic_ops, APR, and other system and
application libraries. The hardware interface provided by LLVM should allow
a clean implementation of all of these APIs and parallel programming models.
No one model or paradigm should be selected above others unless the hardware
itself ubiquitously does so.</p>

<h4>
<a name="int_memory_barrier">'<tt>llvm.memory.barrier</tt>' Intrinsic</a>
</h4>
<div>
<h5>Syntax:</h5>
<pre>
declare void @llvm.memory.barrier(i1 &lt;ll&gt;, i1 &lt;ls&gt;, i1 &lt;sl&gt;, i1 &lt;ss&gt;, i1 &lt;device&gt;)
</pre>
<h5>Overview:</h5>
<p>The <tt>llvm.memory.barrier</tt> intrinsic guarantees ordering between
specific pairs of memory access types.</p>
<h5>Arguments:</h5>
<p>The <tt>llvm.memory.barrier</tt> intrinsic requires five boolean arguments.
The first four arguments enables a specific barrier as listed below. The
fifth argument specifies that the barrier applies to io or device or uncached
memory.</p>
<ul>
<li><tt>ll</tt>: load-load barrier</li>
<li><tt>ls</tt>: load-store barrier</li>
<li><tt>sl</tt>: store-load barrier</li>
<li><tt>ss</tt>: store-store barrier</li>
<li><tt>device</tt>: barrier applies to device and uncached memory also.</li>
</ul>
<h5>Semantics:</h5>
<p>This intrinsic causes the system to enforce some ordering constraints upon
the loads and stores of the program. This barrier does not
indicate <em>when</em> any events will occur, it only enforces
an <em>order</em> in which they occur. For any of the specified pairs of load
and store operations (f.ex. load-load, or store-load), all of the first
operations preceding the barrier will complete before any of the second
operations succeeding the barrier begin. Specifically the semantics for each
pairing is as follows:</p>
<ul>
<li><tt>ll</tt>: All loads before the barrier must complete before any load
after the barrier begins.</li>
<li><tt>ls</tt>: All loads before the barrier must complete before any
store after the barrier begins.</li>
<li><tt>ss</tt>: All stores before the barrier must complete before any
store after the barrier begins.</li>
<li><tt>sl</tt>: All stores before the barrier must complete before any
load after the barrier begins.</li>
</ul>
<p>These semantics are applied with a logical "and" behavior when more than one
is enabled in a single memory barrier intrinsic.</p>
<p>Backends may implement stronger barriers than those requested when they do
not support as fine grained a barrier as requested. Some architectures do
not need all types of barriers and on such architectures, these become
noops.</p>
<h5>Example:</h5>
<pre>
%mallocP = tail call i8* @malloc(i32 ptrtoint (i32* getelementptr (i32* null, i32 1) to i32))
%ptr = bitcast i8* %mallocP to i32*
store i32 4, %ptr
%result1 = load i32* %ptr <i>; yields {i32}:result1 = 4</i>
call void @llvm.memory.barrier(i1 false, i1 true, i1 false, i1 false, i1 true)
<i>; guarantee the above finishes</i>
store i32 8, %ptr <i>; before this begins</i>

<h4>
<a name="int_atomic_cmp_swap">'<tt>llvm.atomic.cmp.swap.*</tt>' Intrinsic</a>
</h4>
<div>
<h5>Syntax:</h5>
<p>This is an overloaded intrinsic. You can use <tt>llvm.atomic.cmp.swap</tt> on
any integer bit width and for different address spaces. Not all targets
support all bit widths however.</p>
<pre>
declare i8 @llvm.atomic.cmp.swap.i8.p0i8(i8* &lt;ptr&gt;, i8 &lt;cmp&gt;, i8 &lt;val&gt;)
declare i16 @llvm.atomic.cmp.swap.i16.p0i16(i16* &lt;ptr&gt;, i16 &lt;cmp&gt;, i16 &lt;val&gt;)
declare i32 @llvm.atomic.cmp.swap.i32.p0i32(i32* &lt;ptr&gt;, i32 &lt;cmp&gt;, i32 &lt;val&gt;)
declare i64 @llvm.atomic.cmp.swap.i64.p0i64(i64* &lt;ptr&gt;, i64 &lt;cmp&gt;, i64 &lt;val&gt;)
</pre>
<h5>Overview:</h5>
<p>This loads a value in memory and compares it to a given value. If they are
equal, it stores a new value into the memory.</p>
<h5>Arguments:</h5>
<p>The <tt>llvm.atomic.cmp.swap</tt> intrinsic takes three arguments. The result
as well as both <tt>cmp</tt> and <tt>val</tt> must be integer values with the
same bit width. The <tt>ptr</tt> argument must be a pointer to a value of
this integer type. While any bit width integer may be used, targets may only
lower representations they support in hardware.</p>
<h5>Semantics:</h5>
<p>This entire intrinsic must be executed atomically. It first loads the value
in memory pointed to by <tt>ptr</tt> and compares it with the
value <tt>cmp</tt>. If they are equal, <tt>val</tt> is stored into the
memory. The loaded value is yielded in all cases. This provides the
equivalent of an atomic compare-and-swap operation within the SSA
framework.</p>
<h5>Examples:</h5>
<pre>
%mallocP = tail call i8* @malloc(i32 ptrtoint (i32* getelementptr (i32* null, i32 1) to i32))
%ptr = bitcast i8* %mallocP to i32*
store i32 4, %ptr
%val1 = add i32 4, 4
%result1 = call i32 @llvm.atomic.cmp.swap.i32.p0i32(i32* %ptr, i32 4, %val1)
<i>; yields {i32}:result1 = 4</i>
%stored1 = icmp eq i32 %result1, 4 <i>; yields {i1}:stored1 = true</i>
%memval1 = load i32* %ptr <i>; yields {i32}:memval1 = 8</i>
%val2 = add i32 1, 1
%result2 = call i32 @llvm.atomic.cmp.swap.i32.p0i32(i32* %ptr, i32 5, %val2)
<i>; yields {i32}:result2 = 8</i>
%stored2 = icmp eq i32 %result2, 5 <i>; yields {i1}:stored2 = false</i>
%memval2 = load i32* %ptr <i>; yields {i32}:memval2 = 8</i>

<h5>Overview:</h5>
<p>This intrinsic loads the value stored in memory at <tt>ptr</tt> and yields
the value from memory. It then stores the value in <tt>val</tt> in the memory
at <tt>ptr</tt>.</p>
<h5>Arguments:</h5>
<p>The <tt>llvm.atomic.swap</tt> intrinsic takes two arguments. Both
the <tt>val</tt> argument and the result must be integers of the same bit

<h5>Syntax:</h5>
<p>This is an overloaded intrinsic. You can use <tt>llvm.atomic.load.add</tt> on
any integer bit width. Not all targets support all bit widths however.</p>

</pre>
<h5>Overview:</h5>
<p>This intrinsic adds <tt>delta</tt> to the value stored in memory
at <tt>ptr</tt>. It yields the original value at <tt>ptr</tt>.</p>
<h5>Arguments:</h5>
<p>The intrinsic takes two arguments, the first a pointer to an integer value
and the second an integer value. The result is also an integer value. These
integer types can have any bit width, but they must all have the same bit
width. The targets may only lower integer representations they support.</p>
<h5>Semantics:</h5>
<p>This intrinsic does a series of operations atomically. It first loads the
value stored at <tt>ptr</tt>. It then adds <tt>delta</tt>, stores the result
to <tt>ptr</tt>. It yields the original value stored at <tt>ptr</tt>.</p>
<h5>Examples:</h5>
<pre>
%mallocP = tail call i8* @malloc(i32 ptrtoint (i32* getelementptr (i32* null, i32 1) to i32))
%ptr = bitcast i8* %mallocP to i32*

<div>
<h5>Syntax:</h5>
<p>This is an overloaded intrinsic. You can use <tt>llvm.atomic.load.sub</tt> on
any integer bit width and for different address spaces. Not all targets
support all bit widths however.</p>
<pre>
declare i8 @llvm.atomic.load.sub.i8.p0i32(i8* &lt;ptr&gt;, i8 &lt;delta&gt;)

<h5>Overview:</h5>
<p>This intrinsic subtracts <tt>delta</tt> to the value stored in memory at
<tt>ptr</tt>. It yields the original value at <tt>ptr</tt>.</p>
<h5>Arguments:</h5>
<p>The intrinsic takes two arguments, the first a pointer to an integer value
and the second an integer value. The result is also an integer value. These
integer types can have any bit width, but they must all have the same bit
width. The targets may only lower integer representations they support.</p>
<h5>Semantics:</h5>
<p>This intrinsic does a series of operations atomically. It first loads the
value stored at <tt>ptr</tt>. It then subtracts <tt>delta</tt>, stores the
result to <tt>ptr</tt>. It yields the original value stored
at <tt>ptr</tt>.</p>

<h3>gwXscript</h3>
<div>
<p><a href="http://botwars.tk/gwscript/">gwXscript</a> is an object oriented,
aspect oriented programming language which can create both executables (ELF,
EXE) and shared libraries (DLL, SO, DYNLIB). The compiler is implemented in
its own language and translates scripts into LLVM-IR which can be optimized
and translated into native code by the LLVM framework. Source code in
gwScript contains definitions that expand the namespaces. So you can build
your project and simply 'plug out' features by removing a file. The remaining
project does not leave scars since you directly separate concerns by the
'template' feature of gwX. It is also possible to add new features to a
project by just adding files and without editing the original project. This
language is used for example to create games or content management systems
that should be extendable.</p>
<p>gwXscript is strongly typed and offers comfort with its native types string,
hash and array. You can easily write new libraries in gwXscript or native
code. gwXscript is type safe and users should not be able to crash your
program or execute malicious code except code that is eating CPU time.</p>

<h3>LanguageKit and Pragmatic Smalltalk</h3>
<div>
<p><a href="http://etoileos.com/etoile/features/languagekit/">LanguageKit</a> is
a framework for implementing dynamic languages sharing an object model with
Objective-C. It provides static and JIT compilation using LLVM along with
its own interpreter. Pragmatic Smalltalk is a dialect of Smalltalk, built on
top of LanguageKit, that interfaces directly with Objective-C, sharing the
same object representation and message sending behaviour. These projects are
developed as part of the &Eacute;toi&eacute; desktop environment.</p>

<h3>Portable OpenCL (pocl)</h3>
<div>
<p>Portable OpenCL is an open source implementation of the OpenCL standard which
can be easily adapted for new targets. One of the goals of the project is
improving performance portability of OpenCL programs, avoiding the need for
target-dependent manual optimizations. A "native" target is included, which

<h3>Pure</h3>
<div>
<p><a href="http://pure-lang.googlecode.com/">Pure</a> is an
algebraic/functional programming language based on term rewriting. Programs
are collections of equations which are used to evaluate expressions in a
symbolic fashion. The interpreter uses LLVM as a backend to JIT-compile Pure
programs to fast native code. Pure offers dynamic typing, eager and lazy
evaluation, lexical closures, a hygienic macro system (also based on term
rewriting), built-in list and matrix support (including list and matrix
comprehensions) and an easy-to-use interface to C and other programming
languages (including the ability to load LLVM bitcode modules, and inline C,
C++, Fortran and Faust code in Pure programs if the corresponding LLVM-enabled
compilers are installed).</p>

<h3>Renderscript</h3>
<div>
<p><a href="http://developer.android.com/guide/topics/renderscript/index.html">Renderscript</a>
is Android's advanced 3D graphics rendering and compute API. It provides a
portable C99-based language with extensions to facilitate common use cases
for enhancing graphics and thread level parallelism. The Renderscript
compiler frontend is based on Clang/LLVM. It emits a portable bitcode format
for the actual compiled script code, as well as reflects a Java interface for
developers to control the execution of the compiled bitcode. Executable
machine code is then generated from this bitcode by an LLVM backend on the
device. Renderscript is thus able to provide a mechanism by which Android
developers can improve performance of their applications while retaining
portability.</p>

compiler built using LLVM. It takes standard, unannotated C/C++ code,
analyzes the code to ensure that memory accesses and array indexing
operations are safe, and instruments the code with run-time checks when
safety cannot be proven statically. SAFECode can be used as a debugging aid
(like Valgrind) to find and repair memory safety bugs. It can also be used
to protect code from security attacks at run-time.</p>

in development, the current implementation supports many features expected of
a modern programming language, such as garbage collection, powerful
bidirectional type inference, a greatly simplified syntax for template
metaprogramming, closures and function literals, reflection, operator
overloading, explicit mutability and immutability, and much more. Tart is
flexible enough to accommodate a broad range of programming styles and
philosophies, while maintaining a strong commitment to simplicity, minimalism
