+Polly - Polyhedral optimizations for LLVM
+-----------------------------------------
+http://polly.llvm.org/
+
+Polly uses a mathematical representation, the polyhedral model, to represent and
+transform loops and other control flow structures. Using an abstract
+representation it is possible to reason about transformations in a more general
+way and to use highly optimized linear programming libraries to figure out the
+optimal loop structure. These transformations can be used to do constant
+propagation through arrays, remove dead loop iterations, optimize loops for
+cache locality, optimize arrays, apply advanced automatic parallelization, drive
+vectorization, or they can be used to do software pipelining.

+\`configure' configures Polly 0.01 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+
+Some influential environment variables:
+  CXX         C++ compiler command
+  CXXFLAGS    C++ compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+//
+// This file defines two classes: MayAliasSet and MayAliasSetInfo.
+// MayAliasSet contains the base pointers of access functions in SCoP that
+// may/must alias each others. And MayAliasSetInfo will compute and hold these
+// MayAliasSets in every SCoP in a function.
+//
+// The difference between MayAliasSet and the original LLVM AliasSet is that
+// the LLVM AliasSets are disjoint, but MayAliasSets are not.
+//
+// Suppose we have the following LLVM IR:
+// define void @f(i32* noalias nocapture %a, i32* noalias nocapture %b)nounwind{
+// bb.nph:
+//   %0 = tail call i32 (...)* @rnd() nounwind
+//   %1 = icmp eq i32 %0, 0
+//   %ptr0 = select i1 %1, i32* %b, i32* %a
+//   %2 = load i32* %ptr0, align 4
+//   %3 = load i32* %a, align 4
+//   %4 = load i32* %b, align 4
+//   ret void
+// }
+//
+// The LLVM AliasSetTracker constructs only one LLVM AliasSet that contains
+// ptr0, a and b, but MayAliasSetInfo is supposed to build two MayAliasSets:
+// {a, ptr0} and {b, ptr0}.
+//
+// Take the above LLVM IR for example, the MayAliasSetInfo builds two set:
+// A: {a, ptr0} and B: {b, ptr0} and constructs base pointer to MayAliasSet
+// mapping like:
+// a -> A
+// b -> B
+// ptr0 -> A, B
+//
+// After that, SCoPInfo pass will build a access function for each MayAliasSet,
+// so "%2 = load i32* %ptr0, align 4" will be translated to "read A" and
+// "read B", while "%3 = load i32* %a, align 4" will be translated to "read A",
+// and "%4 = load i32* %b, align 4" will be translated to "read B". This means
+// we can treat the MayAliasSet as the identifier of the virtual array of memory
+// access in SCoPs.

+// Detect the maximal Scops of a function.
+//
+// A static control part (Scop) is a subgraph of the control flow graph (CFG)
+// that only has statically known control flow and can therefore be described
+// within the polyhedral model.
+//
+// Every Scop fullfills these restrictions:
+//
+// * It is a single entry single exit region
+//
+// * Only affine linear bounds in the loops
+//
+// Every natural loop in a Scop must have a number of loop iterations that can
+// be described as an affine linear function in surrounding loop iterators or
+// parameters. (A parameter is a scalar that does not change its value during
+// execution of the Scop).
+//
+// * Only comparisons of affine linear expressions in conditions
+//
+// * All loops and conditions perfectly nested
+//
+// The control flow needs to be structured such that it could be written using
+// just 'for' and 'if' statements, without the need for any 'goto', 'break' or
+// 'continue'.
+//
+// * Side effect free functions call
+//
+// Only function calls and intrinsics that do not have side effects are allowed
+// (readnone).
+//
+// The Scop detection finds the largest Scops by checking if the largest
+// region is a Scop. If this is not the case, its canonical subregions are
+// checked until a region is a Scop. It is now tried to extend this Scop by
+// creating a larger non canonical region.

+// Detect the maximal Scops of a function.
+//
+// A static control part (Scop) is a subgraph of the control flow graph (CFG)
+// that only has statically known control flow and can therefore be described
+// within the polyhedral model.
+//
+// Every Scop fullfills these restrictions:
+//
+// * It is a single entry single exit region
+//
+// * Only affine linear bounds in the loops
+//
+// Every natural loop in a Scop must have a number of loop iterations that can
+// be described as an affine linear function in surrounding loop iterators or
+// parameters. (A parameter is a scalar that does not change its value during
+// execution of the Scop).
+//
+// * Only comparisons of affine linear expressions in conditions
+//
+// * All loops and conditions perfectly nested
+//
+// The control flow needs to be structured such that it could be written using
+// just 'for' and 'if' statements, without the need for any 'goto', 'break' or
+// 'continue'.
+//
+// * Side effect free functions call
+//
+// Only function calls and intrinsics that do not have side effects are allowed
+// (readnone).
+//
+// The Scop detection finds the largest Scops by checking if the largest
+// region is a Scop. If this is not the case, its canonical subregions are
+// checked until a region is a Scop. It is now tried to extend this Scop by
+// creating a larger non canonical region.

+// The CodeGeneration pass takes a Scop created by ScopInfo and translates it
+// back to LLVM-IR using Cloog.
+//
+// The Scop describes the high level memory behaviour of a control flow region.
+// Transformation passes can update the schedule (execution order) of statements
+// in the Scop. Cloog is used to generate an abstract syntax tree (clast) that
+// reflects the updated execution order. This clast is used to create new
+// LLVM-IR that is computational equivalent to the original control flow region,
+// but executes its code in the new execution order defined by the changed
+// scattering.

+// The Polly code preparation pass is executed before SCoP detection. Its only
+// use is to translate all PHI nodes that can not be expressed by the code
+// generator into explicit memory dependences. Depending of the code generation
+// strategy different PHI nodes are translated:
+//
+// - indvars based code generation:
+//
+// The indvars based code generation requires explicit canonical induction
+// variables. Such variables are generated before scop detection and
+// also before the code preparation pass. All PHI nodes that are not canonical
+// induction variables are not supported by the indvars based code generation
+// and are consequently translated into explict memory accesses.
+//
+// - scev based code generation:
+//
+// The scev based code generation can code generate all PHI nodes that do not
+// reference parameters within the scop. As the code preparation pass is run
+// before scop detection, we can not check this condition, because without
+// a detected scop, we do not know SCEVUnknowns that appear in the SCEV of
+// a PHI node may later be within or outside of the SCoP. Hence, we follow a
+// heuristic and translate all PHI nodes that are either directly SCEVUnknown
+// or SCEVCouldNotCompute. This will hopefully get most of the PHI nodes that
+// are introduced due to conditional control flow, but not the ones that are
+// referencing loop counters.
+//
+// XXX: In the future, we should remove the need for this pass entirely and
+// instead add support for scalar dependences to ScopInfo and code generation.

+/// @brief Register Polly passes such that they form a polyhedral optimizer.
+///
+/// The individual Polly passes are registered in the pass manager such that
+/// they form a full polyhedral optimizer. The flow of the optimizer starts with
+/// a set of preparing transformations that canonicalize the LLVM-IR such that
+/// the LLVM-IR is easier for us to understand and to optimizes. On the
+/// canonicalized LLVM-IR we first run the ScopDetection pass, which detects
+/// static control flow regions. Those regions are then translated by the
+/// ScopInfo pass into a polyhedral representation. As a next step, a scheduling
+/// optimizer is run on the polyhedral representation and finally the optimized
+/// polyhedral representation is code generated back to LLVM-IR.
+///
+/// Besides this core functionality, we optionally schedule passes that provide
+/// a graphical view of the scops (Polly[Only]Viewer, Polly[Only]Printer), that
+/// allow the export/import of the polyhedral representation
+/// (JSCON[Exporter|Importer]) or that show the cfg after code generation.
+///
+/// For certain parts of the Polly optimizer, several alternatives are provided:
+///
+/// As scheduling optimizer we support PoCC (http://pocc.sourceforge.net), PLUTO
+/// (http://pluto-compiler.sourceforge.net) as well as the isl scheduling
+/// optimizer (http://freecode.com/projects/isl). The isl optimizer is the
+/// default optimizer.
+/// It is also possible to run Polly with no optimizer. This mode is mainly
+/// provided to analyze the run and compile time changes caused by the
+/// scheduling optimizer.
+///
+/// Polly supports both CLooG (http://www.cloog.org) as well as the isl internal
+/// code generator. For the moment, the CLooG code generator is enabled by
+/// default.

+///
+/// We currently register Polly such that it runs as early as possible. This has
+/// several implications:
+///
+///   1) We need to schedule more canonicalization passes
+///
+///   As nothing is run before Polly, it is necessary to run a set of preparing
+///   transformations before Polly to canonicalize the LLVM-IR and to allow
+///   Polly to detect and understand the code.
+///
+///   2) LICM and LoopIdiom pass have not yet been run
+///
+///   Loop invariant code motion as well as the loop idiom recognition pass make
+///   it more difficult for Polly to transform code. LICM may introduce
+///   additional data dependences that are hard to eliminate and the loop idiom
+///   recognition pass may introduce calls to memset that we currently do not
+///   understand. By running Polly early enough (meaning before these passes) we
+///   avoid difficulties that may be introduced by these passes.
+///
+///   3) We get the full -O3 optimization sequence after Polly
+///
+///   The LLVM-IR that is generated by Polly has been optimized on a high level,
+///   but it may be rather inefficient on the lower/scalar level. By scheduling
+///   Polly before all other passes, we have the full sequence of -O3
+///   optimizations behind us, such that inefficiencies on the low level can
+///   be optimized away.

+- POLYBENCH_TIME: output execution time (gettimeofday) [default: off]
+- POLYBENCH_NO_FLUSH_CACHE: don't flush the cache before calling the
+  timer [default: flush the cache]
+- POLYBENCH_LINUX_FIFO_SCHEDULER: use FIFO real-time scheduler for the
+  kernel execution, the program must be run as root, under linux only,
+  and compiled with -lc [default: off]
+- POLYBENCH_CACHE_SIZE_KB: cache size to flush, in kB [default: 8192]
+- POLYBENCH_TEST_MALLOC: use malloc instead of stack allocation [default: off]
+- POLYBENCH_DUMP_ARRAYS: dump all live-out arrays on stderr [default: off]
+
+- Nxx: override the default dataset values
+
+
+* Collecting the execution time of all files
+
+$> scripts/runall.sh <machine-name>
+
+Note: the script runall must be run from the root directory of the archive.
+
+
+** Specifying different dataset size for one file in particular
+
+- Create a compiler.opts file under the directory of the benchmark
+- Specify a set of options, e.g. -DX=1024 -DY=1024 (see gemm for an example)
+
+
+** To specify another compiler
+
+- Simplest is to edit scripts/runall.sh, and change the
+  COMPILER_COMMAND variable. One can also export the adequate
+  COMPILER_COMMAND variable in the shell environment.

+
+The llvm.codegen intrinsic generates code for embedded LLVM-IR
+strings. Each call to the intrinsic is replaced by a pointer to
+the newly generated target code. The code generation target can be
+different to the one of the parent module.

++  <a name="int_codegen_intrinsic">'<tt>llvm.codegen</tt>' Intrinsic</a>
++</h4>

++
++<h5>Syntax:</h5>
++<pre>
++  declare i8* @llvm.codegen(i8* &lt;IRString&gt;, i8* &lt;MCPU&gt;, i8* &lt;
++  Features&gt;)
++</pre>
++
++<h5>Overview:</h5>
++<p>The '<tt>llvm.codegen</tt>' intrinsic uses the LLVM back ends to generate
++   code for embedded LLVM-IR strings. The code generation target can be
++   different to the one of the parent module.</p>
++
++<h5>Arguments:</h5>
++<p><tt>IRString</tt> is a string containing LLVM-IR.</p>
++<p><tt>MCPU</tt> is the name of the target CPU.</p>
++<p><tt>Features</tt> is the string representation of the additional target
++   features.</p>
++
++<h5>Semantics:</h5>
++<p>The '<tt>llvm.codegen</tt>' intrinsic transforms a string containing LLVM IR
++   to target assembly code. Calls to the intrinsic are replaced by a pointer to
++   the newly generated target code. In case LLVM can not generate code (e.g. the
++   target is not available), the call to the intrinsic is replaced by a i8 NULL
++   pointer.Users of this intrinsic should make sure the target triple is
++   properly set in the &lt;IRString&gt;. Inputs to both &lt;MCPU&gt; and
++   &lt;Features&gt; parameters can be null pointers.</p>

+"""Command-line parsing library
+
+This module is an optparse-inspired command-line parsing library that:
+
+    - handles both optional and positional arguments
+    - produces highly informative usage messages
+    - supports parsers that dispatch to sub-parsers
+
+The following is a simple usage example that sums integers from the
+command-line and writes the result to a file::
+
+    parser = argparse.ArgumentParser(
+        description='sum the integers at the command line')
+    parser.add_argument(
+        'integers', metavar='int', nargs='+', type=int,
+        help='an integer to be summed')
+    parser.add_argument(
+        '--log', default=sys.stdout, type=argparse.FileType('w'),
+        help='the file where the sum should be written')
+    args = parser.parse_args()
+    args.log.write('%s' % sum(args.integers))
+    args.log.close()
+
+The module contains the following public classes:
+
+    - ArgumentParser -- The main entry point for command-line parsing. As the
+        example above shows, the add_argument() method is used to populate
+        the parser with actions for optional and positional arguments. Then
+        the parse_args() method is invoked to convert the args at the
+        command-line into an object with attributes.
+
+    - ArgumentError -- The exception raised by ArgumentParser objects when
+        there are errors with the parser's actions. Errors raised while
+        parsing the command-line are caught by ArgumentParser and emitted
+        as command-line messages.
+
+    - FileType -- A factory for defining types of files to be created. As the
+        example above shows, instances of FileType are typically passed as
+        the type= argument of add_argument() calls.
+
+    - Action -- The base class for parser actions. Typically actions are
+        selected by passing strings like 'store_true' or 'append_const' to
+        the action= argument of add_argument(). However, for greater
+        customization of ArgumentParser actions, subclasses of Action may
+        be defined and passed as the action= argument.
+
+    - HelpFormatter, RawDescriptionHelpFormatter, RawTextHelpFormatter,
+        ArgumentDefaultsHelpFormatter -- Formatter classes which
+        may be passed as the formatter_class= argument to the
+        ArgumentParser constructor. HelpFormatter is the default,
+        RawDescriptionHelpFormatter and RawTextHelpFormatter tell the parser
+        not to change the formatting for help text, and
+        ArgumentDefaultsHelpFormatter adds information about argument defaults
+        to the help.
+
+All other classes in this module are considered implementation details.
+(Also note that HelpFormatter and RawDescriptionHelpFormatter are only
+considered public as object names -- the API of the formatter objects is
+still considered an implementation detail.)

+            value will be produced.  Other values include:
+                - N (an integer) consumes N arguments (and produces a list)
+                - '?' consumes zero or one arguments
+                - '*' consumes zero or more arguments (and produces a list)

+            with the default, a single value will be produced, while with
+            nargs=1, a list containing a single value will be produced.
+
+        - const -- The value to be produced if the option is specified and the
+            option uses an action that takes no values.
+
+        - default -- The value to be produced if the option is not specified.
+
+        - type -- The type which the command-line arguments should be converted
+            to, should be one of 'string', 'int', 'float', 'complex' or a
+            callable object that accepts a single string argument. If None,
+            'string' is assumed.
+
+        - choices -- A container of values that should be allowed. If not None,
+            after a command-line argument has been converted to the appropriate
+            type, an exception will be raised if it is not a member of this
+            collection.
+
+        - required -- True if the action must always be specified at the
+            command line. This is only meaningful for optional command-line
+            arguments.
+
+        - help -- The help string describing the argument.

+  <h1>Polly - GPGPU Code Generation</h1>
+  <!--*********************************************************************-->
+<p><em>WARNING: This project was part of the Google Summer of Code 2012.
+It is currently not finished, but it is in the design and implementation stage.
+The ideas/plans described here may not yet be implemented in Polly and may
+change later on.</em></p>
+
+This project adds GPGPU code generation feature to Polly.
+
+<h2>Objective</h2>
+<p>The overall objective of this GSoC project is to create a preliminary
+   implementation of GPGPU code generation for Polly. With this addition, users
+   can parallelize some perfectly nested loops with Polly to execute on a
+   heterogeneous platform, composed of CPU and GPU.</p>
+<p>There are several successful projects about automatic source-to-source gpu
+   code transformation. C-to-CUDA[1] uses the standard Pluto algorithms for
+   computing an affine schedule and then applies a wavefront transformation to
+   obtain one sequential and n-1 parallel loops. The parallel loops are then
+   mapped onto the blocks and threads of GPU. PPCG[2] introduces some advanced
+   algorithms which can expose much more parallelism than other methods . And It
+   also introduces affine partition heuristics and code generation algorithms
+   for locality enhancement in the registers and shared memory.</p>
+<p>Since automatic GPGPU code generation is quite a complex problem and what we
+   target is a low-level intermediate representation, LLVM IR, rather than a
+   high-level language source, it is important for us to set a proper objective
+   as a start step to give a complete solution to GPGPU code generation for LLVM
+   IR.</p>
+<p>Firstly, we plan to target two kinds of relatively simple test cases. One is
+   comprised of pure parallel and perfectly nested loops, like the following
+   code.</p>
+<pre>
+parfor(int i=0 to M)
+  parfor(int j=0 to N)
+    LoopBody(i, j);
+</pre>
+<p>Another one is that all the loops in it are parallel except the inner-most
+   one, just like this:</p>
+<pre>
+parfor(int i=0 to M)
+  parfor(int j=0 to N)
+    non-parfor(int k=0 to K)
+      LoopBody(i, j, k);
+</pre>
+<p>The LoopBody part should be limited to instructions or functions calls
+   (intrinsics) which can be handled by LLVM's NVPTX backend.</p>
+<p>On the other hand, we focus on building a preliminary and scalable framework
+   of GPGPU code generation for polly. Thus we plan to employ relatively simple
+   tiling and mapping algorithms and optimize them later.</p>
+<h2>Work Flow</h2>
+<h3>GPGPU Code Generation In General</h3>
+<p>C-to-CUDA[1] and PPCG[2] propose similar steps to solve the automatic GPGPU
+   code generation problem.</p>
+<li>Look for parallel loops.</li>
+<li>Create a polyhedral model from the loops.</li>
+<li>Tile and map the loops to GPU blocks and threads.</li>
+<li>Determine where to place the data.</li>
+<h3>What has been done in Polly</h3>
+<p>Polly has implemented the 1st, 2nd and part of the 3rd of the above steps and
+   many other analysis and transformation passes.</p>
+<h3>What to do in Polly</h3>
+<p>Unlike many source-to-source optimizers such as C-to-CUDA and PPCG, Polly is
+   a low-level optimizer, which means we can't use a source-level compiler
+   (e.g. NVCC) to generate the final assembly for the device. We need manually
+   insert device driver API calls to execute the generated kernel assembly
+   text.</p>
+<p>In this project, we assume that the device driver library has provided an
+   interface to launch kernels in the form of assembly text. Fortunately, most
+   of the mainstream GPU vendors provide such a feature in thier products (see
+   ptxjit of NVIDIA GPUs and CAL of AMD GPUs). Generally speaking, what we
+   are going to do in Polly is:</p>
+<li>Find a way to tile the parallel loops.</li>
+<li>Find a way to extract the loop body and transform it into thread-centric
+    parallel code.</li>
+<li>Find a way to store/load the thread-centric code into/from a device module.
+<li>Find a way to pass the target machine information and generate code of the
+    device module for the target.
+<li>Find a way to map the tiled loop to GPU blocks and threads.</li>
+<li>Find a way to insert CUDA synchronization operations on-demand.
+<li>Find a way to generate the memory copy operations between a host and a
+    device.</li>
+<li>Implement/Wrap a runtime library to serve as the execution engine for the
+    generated device code.</li>
+
+<h3>The Work Flow</h3>
+<p>In this section, we assume that the host cpu is X86 and the device is NVIDIA
+   CUDA-compatible. we will use the following test case to describe our work
+   flow.</p>
+<pre>
+for(i = 0; i &lt; 128; i++)
+      for(j = 0; j &lt; 128; j++)
+              A[i][j] = i*128 + j;
+</pre>
+<p>The work flow of our code generator is as follows.</p>
+<p>1.We first use Polly's jscop file importer to get a wanted 4-level parallel
+   tiled code.</p>
+The "schedule" part of the pre-optimization jscop file is as the following:
+<pre>
+"schedule" : "{ Stmt_for_body3[i0, i1] -&gt; scattering[0, i0, 0, i1, 0] }"
+</pre>
+The jscop file describing the tiling transformation is:
+<pre>
+"schedule" : "{ Stmt_for_body3[i0, i1] -&gt; scattering[0, o0, o1, o2, o3]:
+              o0 &gt;= 0 and o0 &lt;= 7 and o1 &gt;= 0 and o1 &lt;= 15 and
+              o2 &gt;= 0 and o2 &lt;= 7 and o3 &gt;= 0 and o3 &lt;= 15 and
+              i0 = 16o0 + o1 and i1 = 16o2 + o3 }"
+</pre>
+We can test the schedule with the following command line.
+<pre>
+opt -load /path/to/polly/build/LLVMPolly.so -basicaa -polly-import-jscop
+    -polly-cloog -analyze -q ./test.ll
+    -polly-import-jscop-postfix=transformed+gpu
+</pre>
+The output of this schedule is:
+<pre>
+for (c2=0;c2&lt;=7;c2++) {
+  for (c3=0;c3&lt;=15;c3++) {
+    for (c4=0;c4&lt;=7;c4++) {
+      for (c5=0;c5&lt;=15;c5++) {
+        Stmt_for_body3(16*c2+c3,16*c4+c5);
+      }
+    }
+  }
+}
+</pre>
+Now we get a 4-dimensional parallel loops with a single SCoP statement in it.
+<p>2.We then extract the loop body (or the inner-most non-parallel loop) into a
+   LLVM function, tagging it with PTX_Kernel call convention.</p>
+<p>3.We extract the PTX_kernel function into a temporary module, set the target
+   triple (e.g. nvptx64-unknown-linux) for the module, transform the temporary
+   module into a string, store it in the original module and erase the
+   PTX_kernel function.</p>
+<p>4.We replace the loops with their GPGPU counterpart. The GPGPU part of code
+   is composed of a call to the llvm.codegen intrinsic and function calls to our
+   GPU runtime library.</p>
+<p>5.Finally, we generate the executable program with <em>llc</em> or run the
+   optimized LLVM IRs with a JIT compiler like  <em>lli</em>.</p>
+<h2>Usage</h2>
+<p>1. Apply the llvm.codegen intrinsic patch to LLVM code base.</p>
+<pre>cd /path/to/llvm/source
+git am /path/to/polly/source/utils/0001-Add-llvm.codegen-intrinsic.patch</pre>

+  <h1>Polly - Memory access optimizations</h1>
+  <!--*********************************************************************-->
+<p><em>WARNING: This project was part of the Google Summer of Code 2011.
+Tt is currently not finished, but it is in the design and implementation stage.
+The Ideas/Plans described here may not yet be implemented in Polly and may be
+changed during the actual implementation.</em></p>
+
+This project adds memory access transformations to Polly. In many cases
+changing the memory access pattern yields to better data locality or removes
+dependences that would otherwise block transformations.
+
+<p>An examples which uses this feature is given below.</p>
+
+Consider the following loop
+<pre>
+for (i = 0; i < 8; i++)
+  sum += A[i];
+</pre>
+Through memory access transformations this loop can be executed in parallel.
+It can be transformed to
+<pre>
+<em>// Create and initialize an array 'tmp' with size 4</em>
+for (i = 0; i < 8; i++)
+  tmp[i % 4] += A[i];
+sum = tmp[0] + tmp[1] + tmp[2] + tmp[3];
+</pre>
+
+Optimizers like PluTo can schedule the code such that an outer, parallel
+loop is created:
+<pre>
+parfor (ii = 0; ii < 4; ii++) {
+  tmp[ii] = 0;
+  for (i = ii * 2; i < (ii+1) * 2; i++)
+    tmp[ii] += A[i];
+  }
+sum = tmp[0] + tmp[1] + tmp[2] + tmp[3];
+</pre>
+
+<h2>TODO</h2>
+<h3>Step 1</h3>
+Polly exports its polyhedral description in a JSCoP file. Define how memory
+layout transformations are expressed in Polly and in the JSCOP file. 
+Example:
+
+<p>Consider the following loop.</p>
+<pre>
+for (i = 0; i < 12; i++)
+  A[i] = 0;
+</pre>
+In the JSCOP file the memory accesses are represented as follows.
+<pre>
+"accesses": [{
+        "kind": "write",
+                "relation": "{ Stmt[i] -> A[i] }"
+}]
+</pre>
+To perform a transformation we generate the following code:
+<pre>
+for (i = 0; i < 12; i++)
+  A[0] = i;
+</pre>
+The representation in the JSCoP file is:
+<pre>
+"accesses": [{
+        "kind": "read",
+                "relation": "{ Stmt[i] -> A[0] }"
+}]
+</pre>
+We need to detect this access function change.
+
+<h3>Step 2</h3>
+Update the code generation module to reflect the access function change made
+in Step 1.
+<h3>Step 2.1 Code generation for a constant</h3>
+In the JSCOP file an access function which has variables is changed to a
+constant. Code is generated to reflect this change. Let the content of original
+JSCOP file be:
+<pre>
+"accesses" : [{
+        "kind" : "read",
+                 "relation" : "{ Stmt_for_body[i0] -> MemRef_A[i0] }"
+}]
+</pre>
+The transformed JSCOP file is:
+<pre>
+"accesses" : [{
+        "kind" : "read",
+                 "relation" : "{ Stmt_for_body[i0] -> MemRef_A[10] }"
+}]
+</pre>
+Code is generated for this change.
+<h3>Step 2.2 Code generation for coefficients</h3>
+The coefficients of induction variables are changed here. Let the original
+JSCOP file be:
+<pre>
+"accesses" : [{
+      "kind" : "read",
+               "relation" : "{ Stmt_for_body3[i0, i1] -> MemRef_A[32i0+i1] }"
+}]
+</pre>
+The transformed JSCOP file is:
+<pre>
+"accesses" : [{
+      "kind" : "read",
+               "relation" : "{ Stmt_for_body3[i0, i1] -> MemRef_A[16i0+2i1+5] }"
+}]
+</pre>
+Code is generated for this change.

+<h1>Load Polly into clang and automatically run it at -O3</h1>
+<!--=====================================================================-->
+
+<p><b>Warning:</b> Even though this example makes it very easy to use Polly,
+you should be aware that Polly is a young research project. It is expected
+to crash, produce invalid code or to hang in complex calculations even for
+simple examples. In case you see such a problem, please check the <a
+href="bugs.html">Bug database</a> and consider reporting a bug.
+<p>
+<b>Warning II:</b> clang/LLVM/Polly need to be in sync. This means
+            you need to compile them yourself from a recent svn/git checkout</b>
+<h2>Load Polly into clang</h2>
+
+By loading Polly into clang (or opt) the Polly options become automatically
+available. You can load Polly either by adding the relevant commands to
+the CPPFLAGS or by creating an alias.
+
+<pre class="code">
+$ export CPPFLAGS="-Xclang -load -Xclang ${POLLY_BUILD_DIR}/lib/LLVMPolly.so"
+</pre>
+
+or
+<pre class="code">
+$ alias pollycc clang -Xclang -load -Xclang ${POLLY_BUILD_DIR}/lib/LLVMPolly.so
+</pre>
+
+<h2>Optimizing with Polly</h2>
+
+Optimizing with Polly is as easy as adding <b>-O3 -mllvm -polly</b> to your
+compiler flags (Polly is only available at -O3).
+
+<pre class="code">pollycc -O3 -mllvm -polly file.c</pre>
+
+<h2>Automatic OpenMP code generation</h2>
+
+To automatically detect parallel loops and generate OpenMP code for them you
+also need to add <b>-mllvm -enable-polly-openmp -lgomp</b> to your CFLAGS.
+
+<pre class="code">pollycc -O3 -mllvm -polly -mllvm -enable-polly-openmp -lgomp file.c</pre>
+
+<h2>Automatic Vector code generation</h2>
+
+Automatic vector code generation can be enabled by adding <b>-mllvm
+-polly-vectorizer=polly</b> to your CFLAGS.
+
+<pre class="code">pollycc -O3 -mllvm -polly -mllvm -polly-vectorizer=polly file.c</pre>
+
+<h2>Extract a preoptimized LLVM-IR file</h2>
+
+Often it is useful to derive from a C-file the LLVM-IR code that is actually
+optimized by Polly. Normally the LLVM-IR is automatically generated from
+the C code by first lowering C to LLVM-IR (clang) and by subsequently applying a
+set of preparing transformations on the LLVM-IR. To get the LLVM-IR after the
+preparing transformations have been applied run Polly with '-O0'.
+
+<pre class="code">pollycc -O0 -mllvm -polly -S -emit-llvm file.c</pre>
+
+<h2>Further options</h2>
+
+Polly supports further options that are mainly useful for the development or
+the
+analysis of Polly. The relevant options can be added to clang by appending
+<b>-mllvm -option-name</b> to the CFLAGS or the clang
+command line.
+
+<h3>Limit Polly to a single function</h3>
+To limit the execution of Polly to a single function, use the option
+<b>-polly-detect-only=functionname</b>.
+
+<h3>Disable LLVM-IR generation</h3>
+Polly normally regenerates LLVM-IR from the Polyhedral representation. To only
+see the effects of the preparing transformation, but to disable Polly code
+generation add the option <b>polly-no-codegen</b>.
+
+<h3>Graphical view of the SCoPs</h3>
+
+Polly can use graphviz to show the SCoPs it detects in a program. The relevant
+options are <b>-polly-show</b>, <b>-polly-show-only</b>, <b>-polly-dot</b> and
+<b>-polly-dot-only</b>. The 'show' options automatically run dotty or another
+graphviz viewer to show the scops graphically. The 'dot' options store for each
+function a dot file that highlights the detected SCoPs. If 'only' is appended at
+the end of the option, the basic blocks are shown without the statements the
+contain.
+
+<h3>Change/Disable the Optimizer</h3>
+Polly uses by default the isl scheduling optimizer. The isl optimizer optimizes
+for data-locality and parallelism using the <a
+href="http://pluto-compiler.sf.net">Pluto</a> algorithm. For research it is also
+possible to run <a
+href="http://www-rocq.inria.fr/~pouchet/software/pocc/">PoCC</a> as external
+optimizer. PoCC provides access to the original Pluto implementation. To use
+PoCC add <b>-polly-optimizer=pocc</b> to the command line (only available if
+Polly was compiled with scoplib support). To disable the
+optimizer entirely use the option <b>-polly-optimizer=none</b>.
+
+<h3>Disable tiling in the optimizer</h3>
+By default both optimizers perform tiling, if possible. In case this is not
+wanted the option <b>-polly-no-tiling</b> can be used to disable it. (This
+option disables tiling for both optimizers).
+
+<h3>Ignore possible aliasing</h3>
+By default we only detect scops, if we can prove that the different array bases
+can not alias. This is correct do if we optimize automatically.  However,
+without special user annotations like 'restrict' we can often not prove that
+no aliasing is possible. In case the user knows no aliasing can happen in the
+code the <b>-polly-ignore-aliasing</b> can be used to disable the check for
+possible aliasing.
+
+<h3>Import / Export</h3>
+The flags <b>-polly-import</b> and <b>-polly-export</b> allow the export and
+reimport of the polyhedral representation. By exporting, modifying and
+reimporting the polyhedral representation externally calculated transformations
+can be applied. This enables external optimizers or the manual optimization of
+specific SCoPs.

+<!--=====================================================================-->
+
+<p><b>Note:</b>This is a quick note on how to load Polly into

+  available with Polly, only the syntax is different.
+  The <a href="example_load_Polly_into_clang.html">examples for use
+  with clang</a> can also be performed with Polly, with suitable
+  corrections in the syntax.
+
+<h2>Compile dragonegg with support for LLVM plugins</h2>
+
+The support for LLVM plugins in dragonegg is still experimental, and
+hence protected by a build option. You must rebuild dragonegg with the
+following options:
+
+<pre class="code">
+$ GCC=${PATH_TO_GCC} LLVM_CONFIG=${PATH_TO_LLVM_CONFIG} ENABLE_LLVM_PLUGINS=1 make
+</pre>
+
+<h2>Load Polly into dragonegg</h2>
+
+By loading Polly into dragonegg, the Polly options become automatically
+available. You can load Polly either by adding the relevant commands to
+the CPPFLAGS or by creating an alias.
+
+<pre class="code">
+$ export CPPFLAGS="-fplugin=/path/to/dragonegg.so -fplugin-arg-dragonegg-llvm-option=-load:${POLLY_BUILD_DIR}/lib/LLVMPolly.so"

+
+<pre class="code">pollycc -O3 -fplugin-arg-dragonegg-llvm-option=-polly file.c</pre>
+
+<h2>Passing various options to Polly</h2>
+
+As must be evident from the examples so far, options to LLVM and its
+plugins are passed via the <b>-fplugin-arg-dragonegg-llvm-option</b>
+commandline argment.
+The <a href="example_load_Polly_into_clang.html">examples for use with

+<h1>Polly: Execute the individual Polly passes manually</h1>
+<!--=====================================================================-->
+
+<p>
+This example presents the individual passes that are involved when optimizing
+code with Polly. We show how to execute them individually and explain for each
+which analysis is performed or what transformation is applied. In this example
+the polyhedral transformation is user-provided to show how much performance
+improvement can be expected by an optimal automatic optimizer.</p>
+
+The files used and created in this example are available in the Polly checkout
+in the folder <em>www/experiments/matmul</em>. They can be created automatically
+by running the <em>www/experiments/matmul/runall.sh</em> script.
+
+<ol>
+<li><h4>Create LLVM-IR from the C code</h4>
+
+Polly works on LLVM-IR. Hence it is necessary to translate the source files into
+LLVM-IR. If more than on file should be optimized the files can be combined into
+a single file with llvm-link.
+
+<pre class="code">clang -S -emit-llvm matmul.c -o matmul.s</pre>
+</li>
+
+
+<li><h4>Load Polly automatically when calling the 'opt' tool</h4>
+
+Polly is not built into opt or bugpoint, but it is a shared library that needs
+to be loaded into these tools explicitally. The Polly library is called
+LVMPolly.so. For a cmake build it is available in the build/lib/ directory,
+autoconf creates the same file in
+build/tools/polly/{Release+Asserts|Asserts|Debug}/lib. For convenience we create
+an alias that automatically loads Polly if 'opt' is called.
+<pre class="code">
+export PATH_TO_POLLY_LIB="~/polly/build/lib/"
+alias opt="opt -load ${PATH_TO_POLLY_LIB}/LLVMPolly.so"</pre>
+</li>
+
+<li><h4>Prepare the LLVM-IR for Polly</h4>
+
+Polly is only able to work with code that matches a canonical form. To translate
+the LLVM-IR into this form we use a set of canonicalication passes. For this
+example only three passes are necessary. To get good coverage on more
+complicated input files often more canonicalization passes are needed. pollycc
+contains a list of passes that have shown to be beneficial.
+<pre class="code">opt -S -mem2reg -loop-simplify -polly-indvars matmul.s &gt; matmul.preopt.ll</pre></li>
+
+<li><h4>Show the SCoPs detected by Polly (optional)</h4>
+
+To understand if Polly was able to detect SCoPs, we print the
+structure of the detected SCoPs. In our example two SCoPs were detected. One in
+'init_array' the other in 'main'.
+
+<pre class="code">opt -basicaa -polly-cloog -analyze -q matmul.preopt.ll</pre>
+
+<pre>
+init_array():
+for (c2=0;c2&lt;=1023;c2++) {
+  for (c4=0;c4&lt;=1023;c4++) {
+    Stmt_5(c2,c4);
+  }
+}
+
+main():
+for (c2=0;c2&lt;=1023;c2++) {
+  for (c4=0;c4&lt;=1023;c4++) {
+    Stmt_4(c2,c4);

+parallelism.

+significantly.

+<h1>Getting Started: Building and Installing Polly</h1>
+
+<h2> Automatic </h2>
+
+There is a <a href="polly.sh">script</a> available to automatically checkout,
+update, build, and test Polly. This script contains all the commands that are
+subsequently described on this webpage. The automatic installation consists
+of four simple steps:
+
+<pre>
+mkdir polly &amp;&amp; cd polly
+wget http://polly.llvm.org/polly.sh
+chmod +x polly.sh
+./polly.sh
+</pre>
+
+<h2> Manual </h2>
+<h3 id="source"> Get the code </h3>
+
+The Polly source code is available in the LLVM SVN repository as well as through
+an official git mirror. It is added to the <em>tools</em>
+directory of the llvm sources.
+<b>Polly and LLVM need to be checked out at the same time. Checkouts
+   from different dates may not work!</b>
+<h4>Set the directory layout:</h4>
+<pre>
+export BASE=`pwd`
+export LLVM_SRC=${BASE}/llvm
+export POLLY_SRC=${LLVM_SRC}/tools/polly
+
+# Also build the matching clang-version (optional)
+export CLANG_SRC=${LLVM_SRC}/tools/clang
+</pre>
+
+<h4>SVN</h4>
+<pre>
+svn checkout http://llvm.org/svn/llvm-project/llvm/trunk ${LLVM_SRC}
+svn checkout http://llvm.org/svn/llvm-project/polly/trunk ${POLLY_SRC}
+
+# Also build the matching clang-version (optional)
+svn checkout http://llvm.org/svn/llvm-project/cfe/trunk ${CLANG_SRC}
+</pre>
+<h4>GIT</h4>
+<pre>
+git clone http://llvm.org/git/llvm.git ${LLVM_SRC}
+git clone http://llvm.org/git/polly.git ${POLLY_SRC}
+
+# Also build the matching clang-version (optional)
+git clone http://llvm.org/git/clang.git ${CLANG_SRC}
+</pre>
+<h3 id="prerequisites"> Prerequisites </h3>
+<ul>
+<li>libgmp</li>
+<li>CLooG/isl</li>
+</ul>
+
+<h4> libgmp </h4>
+Install libgmp (library + developer package) through the package management
+system of your operating system.
+
+<h4> CLooG/isl</h4>
+
+Polly is tested with a fixed version of <a href="http://www.cloog.org">CLooG</a>
+and isl. To obtain the source code of CLooG (including isl) use
+checkout_cloog.sh as available in ${POLLY_SRC}/utils/checkout_cloog.sh.
+
+<h4>Set the directory layout:</h4>
+<pre>
+export CLOOG_SRC=${BASE}/cloog_src
+export CLOOG_INSTALL=${BASE}/cloog_install
+</pre>
+
+<h4> First installation</h4>
+<pre>
+${POLLY_SRC}/utils/checkout_cloog.sh ${CLOOG_SRC}
+cd ${CLOOG_SRC}
+./configure --prefix=${CLOOG_INSTALL}
+make
+make install
+cd ${BASE}
+</pre>
+
+<h4> Update the installation</h4>
+
+Updating CLooG may become necessary, if Polly uses a feature
+only available in a recent version of CLooG.
+<pre>
+${POLLY_SRC}/utils/checkout_cloog.sh ${CLOOG_SRC}
+cd ${CLOOG_SRC}
+make
+make install
+cd ${BASE}
+</pre>
+
+<h3 id="build">Build Polly</h3>
+
+To build Polly you can either use the autoconf or the cmake build system. At the
+moment only the autoconf build system allows to run the llvm test-suite and only
+the cmake build system allows to run 'make polly-test'.
+
+<h4>Set the directory layout:</h4>
+<pre>
+export LLVM_BUILD=${BASE}/llvm_build
+mkdir ${LLVM_BUILD}
+cd ${LLVM_BUILD}
+</pre>
+
+<h4>CMake</h4>
+
+<pre>
+cmake -DCMAKE_PREFIX_PATH=${CLOOG_INSTALL} ${LLVM_SRC}
+make
+</pre>
+
+<h4> Autoconf </h4>
+
+<pre>
+${LLVM_SRC}/configure --with-cloog=${CLOOG_INSTALL} --with-isl=${CLOOG_INSTALL}
+make
+</pre>
+
+<h3> Test Polly</h3>
+
+<p>To check if Polly works correctly you can run <em>make polly-test</em> for the
+cmake build or <em>make polly-test -C tools/polly/test/</em> for the autoconf
+build.
+
+<p>If you get something like <em>"... libisl.so.9: cannot open shared object file .."</em>,
+it is because you installed cloog to a non-standard path, and libisl/libcloog
+could not be found. To solve this issue, you need to append the path of parent
+directory of libisl/libcloog, i.e. ${CLOOG_INSTALL}/lib, to LD_LIBRARY_PATH by:
+
+<pre>export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${CLOOG_INSTALL}/lib</pre>
+
+<h2> Optional Features </h2>
+
+<h3> Pocc </h3>
+
+<p>Polly can use <a href="http://www.cse.ohio-state.edu/~pouchet/software/pocc">
+PoCC</a> as an external optimizer. PoCC is a research project that provides
+an integrated version of <a href="http://pluto.sf.net">Pluto</a>, an
+advanced data-locality and tileability optimizer. Polly includes internally
+already a similar optimizer, such that in general PoCC is not needed. It is
+only recommended for people who want to compare against a different
+optimizer.</a>
+<br/>
+To use it install PoCC 1.0-rc3.1 (the one with Polly support) and add it to your PATH. 
+
+<pre>
+wget <a
+href="http://www.cse.ohio-state.edu/~pouchet/software/pocc/download/pocc-1.0-rc3.1-full.tar.gz">http://www.cse.ohio-state.edu/~pouchet/software/pocc/download/pocc-1.0-rc3.1-full.tar.gz</a>
+tar xzf pocc-1.0-rc3.1-full.tar.gz
+cd pocc-1.0-rc3.1
+./install.sh
+export PATH=$PATH:`pwd`/bin
+</pre>
+
+You also need to install scoplib-0.2.0 and provide its location to
+Polly's cmake or configure call.
+
+<pre>
+wget <a
+href="http://www.cse.ohio-state.edu/~pouchet/software/pocc/download/modules/scoplib-0.2.0.tar.gz"
+>http://www.cse.ohio-state.edu/~pouchet/software/pocc/download/modules/scoplib-0.2.0.tar.gz</a>
+tar xzf  scoplib-0.2.0.tar.gz
+cd scoplib-0.2.0
+./configure --enable-mp-version --prefix=/path/to/scoplib/installation
+make && make install
+</pre>

+  <h1>Polly: Polyhedral optimizations for LLVM</h1>
+  <!--*********************************************************************-->
+
+  <p> Polly is a polyhedral optimizer for LLVM. Using an abstract mathematical
+      representation it analyzes and optimizes the memory access pattern of a
+      program. This includes data-locality optimizations for cache locality as
+      well as automatic parallelization for thread-level and SIMD parallelism.
+      Our overall goal is an integrated optimizer for data-locality and
+      parallelism that takes advantage of multi-cores, cache hierarchies, short
+      vector instructions as well as dedicated accelerators.</p>

+  <b>WARNING:</b> Polly started as a research project and larger parts of it are

+  of Polly in production, as well as researcher, who is more interested in using
+  his expertise to work on some of the open research projects.

+<h1>Polly: Performance</h1>
+
+<p>To evaluate the performance benefits Polly currently provides we compiled the
+<a href="http://www.cse.ohio-state.edu/~pouchet/software/polybench/">Polybench
+2.0</a> benchmark suite.  Each benchmark was run with double precision floating
+point values on an Intel Core Xeon X5670 CPU @ 2.93GHz (12 cores, 24 thread)
+system. We used <a href="http://pocc.sf.net">PoCC</a> and the included <a
+href="http://pluto-compiler.sf.net">Pluto</a> transformations to optimize the
+code. The source code of Polly and LLVM/clang was checked out on 
+25/03/2011.</p>
+
+<p>The results shown were created fully automatically without manual
+interaction. We did not yet spend any time to tune the results. Hence
+further improvments may be achieved by tuning the code generated by Polly, the
+heuristics used by Pluto or by investigating if more code could be optimized.
+As Pluto was never used at such a low level, its heuristics are probably
+far from perfect. Another area where we expect larger performance improvements
+is the SIMD vector code generation. At the moment, it rarely yields to
+performance improvements, as we did not yet include vectorization in our
+heuristics. By changing this we should be able to significantly increase the
+number of test cases that show improvements.</p>
+
+<p>The polybench test suite contains computation kernels from linear algebra
+routines, stencil computations, image processing and data mining. Polly
+recognices the majority of them and is able to show good speedup. However,
+to show similar speedup on larger examples like the SPEC CPU benchmarks Polly
+still misses support for integer casts, variable-sized multi-dimensional arrays
+and probably several other construts. This support is necessary as such
+constructs appear in larger programs, but not in our limited test suite.
+
+<h2> Sequential runs</h2>
+
+For the sequential runs we used Polly to create a program structure that is
+optimized for data-locality. One of the major optimizations performed is tiling.
+The speedups shown are without the use of any multi-core parallelism. No
+additional hardware is used, but the single available core is used more
+efficiently.
+<h3> Small data size</h3>
+<img src="images/performance/sequential-small.png" /><br />
+<h3> Large data size</h3>
+<img src="images/performance/sequential-large.png" />
+<h2> Parallel runs</h2>
+For the parallel runs we used Polly to expose parallelism and to add calls to an
+OpenMP runtime library. With OpenMP we can use all 12 hardware cores
+instead of the single core that was used before. We can see that in several
+cases we obtain more than linear speedup. This additional speedup is due to
+improved data-locality.
