-/**
- * A <i>kernel</i> encapsulates a data parallel algorithm that will execute either on a GPU
- * (through conversion to OpenCL) or on a CPU via a Java Thread Pool.
- * <p>
- * To write a new kernel, a developer extends the <code>Kernel</code> class and overrides the <code>Kernel.run()</code> method.
- * To execute this kernel, the developer creates a new instance of it and calls <code>Kernel.execute(int globalSize)</code> with a suitable 'global size'. At runtime
- * Aparapi will attempt to convert the <code>Kernel.run()</code> method (and any method called directly or indirectly
- * by <code>Kernel.run()</code>) into OpenCL for execution on GPU devices made available via the OpenCL platform.
- * <p>
- * Note that <code>Kernel.run()</code> is not called directly. Instead,
- * the <code>Kernel.execute(int globalSize)</code> method will cause the overridden <code>Kernel.run()</code>
- * method to be invoked once for each value in the range <code>0...globalSize</code>.
- * <p>
- * On the first call to <code>Kernel.execute(int _globalSize)</code>, Aparapi will determine the EXECUTION_MODE of the kernel.
- * This decision is made dynamically based on two factors:
- * <ol>
- * <li>Whether OpenCL is available (appropriate drivers are installed and the OpenCL and Aparapi dynamic libraries are included on the system path).</li>
- * <li>Whether the bytecode of the <code>run()</code> method (and every method that can be called directly or indirectly from the <code>run()</code> method)
- * can be converted into OpenCL.</li>
- * </ol>
- * <p>
- * Below is an example Kernel that calculates the square of a set of input values.
- * <p>
- * <blockquote><pre>
- * class SquareKernel extends Kernel{
- * private int values[];
- * private int squares[];
- * public SquareKernel(int values[]){
- * this.values = values;
- * squares = new int[values.length];
- * }
- * public void run() {
- * int gid = getGlobalID();
- * squares[gid] = values[gid]*values[gid];
- * }
- * public int[] getSquares(){
- * return(squares);
- * }
- * }
- * </pre></blockquote>
- * <p>
- * To execute this kernel, first create a new instance of it and then call <code>execute(Range _range)</code>.
- * <p>
- * <blockquote><pre>
- * int[] values = new int[1024];
- * // fill values array
- * Range range = Range.create(values.length); // create a range 0..1024
- * SquareKernel kernel = new SquareKernel(values);
- * kernel.execute(range);
- * </pre></blockquote>
- * <p>
- * When <code>execute(Range)</code> returns, all the executions of <code>Kernel.run()</code> have completed and the results are available in the <code>squares</code> array.
- * <p>
- * <blockquote><pre>
- * int[] squares = kernel.getSquares();
- * for (int i=0; i< values.length; i++){
- * System.out.printf("%4d %4d %8d\n", i, values[i], squares[i]);
- * }
- * </pre></blockquote>
- * <p>
- * A different approach to creating kernels that avoids extending Kernel is to write an anonymous inner class:
- * <p>
- * <blockquote><pre>
- *
- * final int[] values = new int[1024];
- * // fill the values array
- * final int[] squares = new int[values.length];
- * final Range range = Range.create(values.length);
- *
- * Kernel kernel = new Kernel(){
- * public void run() {
- * int gid = getGlobalID();
- * squares[gid] = values[gid]*values[gid];
- * }
- * };
- * kernel.execute(range);
- * for (int i=0; i< values.length; i++){
- * System.out.printf("%4d %4d %8d\n", i, values[i], squares[i]);
- * }
- *
- * </pre></blockquote>

+/**
+ * A <i>kernel</i> encapsulates a data parallel algorithm that will execute either on a GPU
+ * (through conversion to OpenCL) or on a CPU via a Java Thread Pool.
+ * <p>
+ * To write a new kernel, a developer extends the <code>Kernel</code> class and overrides the <code>Kernel.run()</code> method.
+ * To execute this kernel, the developer creates a new instance of it and calls <code>Kernel.execute(int globalSize)</code> with a suitable 'global size'. At runtime
+ * Aparapi will attempt to convert the <code>Kernel.run()</code> method (and any method called directly or indirectly
+ * by <code>Kernel.run()</code>) into OpenCL for execution on GPU devices made available via the OpenCL platform.
+ * <p>
+ * Note that <code>Kernel.run()</code> is not called directly. Instead,
+ * the <code>Kernel.execute(int globalSize)</code> method will cause the overridden <code>Kernel.run()</code>
+ * method to be invoked once for each value in the range <code>0...globalSize</code>.
+ * <p>
+ * On the first call to <code>Kernel.execute(int _globalSize)</code>, Aparapi will determine the EXECUTION_MODE of the kernel.
+ * This decision is made dynamically based on two factors:
+ * <ol>
+ * <li>Whether OpenCL is available (appropriate drivers are installed and the OpenCL and Aparapi dynamic libraries are included on the system path).</li>
+ * <li>Whether the bytecode of the <code>run()</code> method (and every method that can be called directly or indirectly from the <code>run()</code> method)
+ * can be converted into OpenCL.</li>
+ * </ol>
+ * <p>
+ * Below is an example Kernel that calculates the square of a set of input values.
+ * <p>
+ * <blockquote><pre>
+ * class SquareKernel extends Kernel{
+ * private int values[];
+ * private int squares[];
+ * public SquareKernel(int values[]){
+ * this.values = values;
+ * squares = new int[values.length];
+ * }
+ * public void run() {
+ * int gid = getGlobalID();
+ * squares[gid] = values[gid]*values[gid];
+ * }
+ * public int[] getSquares(){
+ * return(squares);
+ * }
+ * }
+ * </pre></blockquote>
+ * <p>
+ * To execute this kernel, first create a new instance of it and then call <code>execute(Range _range)</code>.
+ * <p>
+ * <blockquote><pre>
+ * int[] values = new int[1024];
+ * // fill values array
+ * Range range = Range.create(values.length); // create a range 0..1024
+ * SquareKernel kernel = new SquareKernel(values);
+ * kernel.execute(range);
+ * </pre></blockquote>
+ * <p>
+ * When <code>execute(Range)</code> returns, all the executions of <code>Kernel.run()</code> have completed and the results are available in the <code>squares</code> array.
+ * <p>
+ * <blockquote><pre>
+ * int[] squares = kernel.getSquares();
+ * for (int i=0; i< values.length; i++){
+ * System.out.printf("%4d %4d %8d\n", i, values[i], squares[i]);
+ * }
+ * </pre></blockquote>
+ * <p>
+ * A different approach to creating kernels that avoids extending Kernel is to write an anonymous inner class:
+ * <p>
+ * <blockquote><pre>
+ *
+ * final int[] values = new int[1024];
+ * // fill the values array
+ * final int[] squares = new int[values.length];
+ * final Range range = Range.create(values.length);
+ *
+ * Kernel kernel = new Kernel(){
+ * public void run() {
+ * int gid = getGlobalID();
+ * squares[gid] = values[gid]*values[gid];
+ * }
+ * };
+ * kernel.execute(range);
+ * for (int i=0; i< values.length; i++){
+ * System.out.printf("%4d %4d %8d\n", i, values[i], squares[i]);
+ * }
+ *
+ * </pre></blockquote>

-/**
- *
- * A representation of 1, 2 or 3 dimensional range of execution.
- *
- * This class uses factory methods to allow one, two or three dimensional ranges to be created.
- * <br/>
- * For a Kernel operating over the linear range 0..1024 without a specified groups size we would create a one dimensional <code>Range</code> using
- * <blockquote><pre>Range.create(1024);</pre></blockquote>
- * To request the same linear range but with a groupSize of 64 (range must be a multiple of group size!) we would use
- * <blockquote><pre>Range.create(1024,64);</pre></blockquote>
- * To request a two dimensional range over a grid (0..width)x(0..height) where width==512 and height=256 we would use
- * <blockquote><pre>
- * int width=512;
- * int height=256;
- * Range.create2D(width,height)
- * </pre></blockquote>
- * Again the above does not specify the group size. One will be chosen for you. If you want to specify the groupSize (say 16x8; 16 wide by 8 high) use
- * <blockquote><pre>
- * int width=512;
- * int height=256;
- * int groupWidth=16;
- * int groupHeight=8;
- * Range.create2D(width, height, groupWidth, groupHeight);
- * </pre></blockquote>
- * Finally we can request a three dimensional range using
- * <blockquote><pre>
- * int width=512;
- * int height=256;
- * int depth=8;
- * Range.create3D(width, height, depth);
- * </pre></blockquote>
- * And can specify a group size using
- * <blockquote><pre>
- * int width=512;
- * int height=256;
- * int depth=8;
- * int groupWidth=8;
- * int groupHeight=4;
- * int groupDepth=2
- * Range.create3D(width, height, depth, groupWidth, groupHeight, groupDepth);
- * </pre></blockquote>

+/**
+ *
+ * A representation of 1, 2 or 3 dimensional range of execution.
+ *
+ * This class uses factory methods to allow one, two or three dimensional ranges to be created.
+ * <br/>
+ * For a Kernel operating over the linear range 0..1024 without a specified groups size we would create a one dimensional <code>Range</code> using
+ * <blockquote><pre>Range.create(1024);</pre></blockquote>
+ * To request the same linear range but with a groupSize of 64 (range must be a multiple of group size!) we would use
+ * <blockquote><pre>Range.create(1024,64);</pre></blockquote>
+ * To request a two dimensional range over a grid (0..width)x(0..height) where width==512 and height=256 we would use
+ * <blockquote><pre>
+ * int width=512;
+ * int height=256;
+ * Range.create2D(width,height)
+ * </pre></blockquote>
+ * Again the above does not specify the group size. One will be chosen for you. If you want to specify the groupSize (say 16x8; 16 wide by 8 high) use
+ * <blockquote><pre>
+ * int width=512;
+ * int height=256;
+ * int groupWidth=16;
+ * int groupHeight=8;
+ * Range.create2D(width, height, groupWidth, groupHeight);
+ * </pre></blockquote>
+ * Finally we can request a three dimensional range using
+ * <blockquote><pre>
+ * int width=512;
+ * int height=256;
+ * int depth=8;
+ * Range.create3D(width, height, depth);
+ * </pre></blockquote>
+ * And can specify a group size using
+ * <blockquote><pre>
+ * int width=512;
+ * int height=256;
+ * int depth=8;
+ * int groupWidth=8;
+ * int groupHeight=4;
+ * int groupDepth=2
+ * Range.create3D(width, height, depth, groupWidth, groupHeight, groupDepth);
+ * </pre></blockquote>

-/**
- * Deals with the issue of recognizing that a sequence of bytecode branch instructions actually represent a single if/while with a logical expression.
- *
- * <p>
- * A logical expressions such as
- * <pre><code>
- if (i>= 0 && i%2 == 0 && i<100){}
- * </code></pre>
- * gets translated into a sequence of bytecode level branches and targets. Which might look like the following.
- * <pre><code>
- a: if ? e +
- b: if ? d |+
- c: if ? e ||+
- d: if ? out |v|+
- e: ... v v|
- ... |
- out: _instruction v
- * </code></pre>
- * We need an algorithm for recognizing the underlying logical expression.
- * <p>
- * Essentially, given a set of branches, get the longest sequential sequence including the input set which target each other or _target.
- *
- * Branches can legally branch to another in the valid set, or to the fall through of the last in the valid set or to _target
- *<p>
- * So an <pre>if(COND){IF_INSTRUCTIONS}else{ELSE_INSTUCTIONS}...</pre> will be
-<pre><code>
- branch[?? branch]*, instructions*,goto,instruction*,target
-</code></pre>
- * and <pre>if(COND){IF_INSTRUCTIONS}...</pre> will be :-
-<code><pre>
- branch[?? branch]*,instruction*,target
-</pre></code>
- * The psuedo code code the algorithm looks like this:
-<code><pre>
- int n=0;
- while (exp.length >1){
- if (exp[n].target == exp[n+1].target){ #rule 1
- replace exp[n] and exp[n+1] with a single expression representing 'exp[n] || exp[n+1]'
- n=0;
- }else if (exp[n].target == exp[n+1].next){ #rule 2
- replace exp[n] and exp[n+1] with a single expression representing '!(exp[n]) && exp[n+1]
- n=0;
- }else{ #rule 3
- n++;
- }
- }
-
- result = !exp[0];
-</pre></code>

+/**
+ * Deals with the issue of recognizing that a sequence of bytecode branch instructions actually represent a single if/while with a logical expression.
+ *
+ * <p>
+ * A logical expressions such as
+ * <pre><code>
+ if (i>= 0 && i%2 == 0 && i<100){}
+ * </code></pre>
+ * gets translated into a sequence of bytecode level branches and targets. Which might look like the following.
+ * <pre><code>
+ a: if ? e +
+ b: if ? d |+
+ c: if ? e ||+
+ d: if ? out |v|+
+ e: ... v v|
+ ... |
+ out: _instruction v
+ * </code></pre>
+ * We need an algorithm for recognizing the underlying logical expression.
+ * <p>
+ * Essentially, given a set of branches, get the longest sequential sequence including the input set which target each other or _target.
+ *
+ * Branches can legally branch to another in the valid set, or to the fall through of the last in the valid set or to _target
+ *<p>
+ * So an <pre>if(COND){IF_INSTRUCTIONS}else{ELSE_INSTUCTIONS}...</pre> will be
+<pre><code>
+ branch[?? branch]*, instructions*,goto,instruction*,target
+</code></pre>
+ * and <pre>if(COND){IF_INSTRUCTIONS}...</pre> will be :-
+<code><pre>
+ branch[?? branch]*,instruction*,target
+</pre></code>
+ * The psuedo code code the algorithm looks like this:
+<code><pre>
+ int n=0;
+ while (exp.length >1){
+ if (exp[n].target == exp[n+1].target){ #rule 1
+ replace exp[n] and exp[n+1] with a single expression representing 'exp[n] || exp[n+1]'
+ n=0;
+ }else if (exp[n].target == exp[n+1].next){ #rule 2
+ replace exp[n] and exp[n+1] with a single expression representing '!(exp[n]) && exp[n+1]
+ n=0;
+ }else{ #rule 3
+ n++;
+ }
+ }
+
+ result = !exp[0];

- * DUP family of instructions break our stack unwind model (whereby we treat instructions like the oeprands they create/consume).
- *
- * <p>
- * Here we replace DUP style instructions with a 'mock' instruction which 'clones' the effect of the instruction. This would be invalid to execute but is useful
- * to replace the DUP with a 'pattern' which it simulates. This allows us to later apply transforms to represent the original code.
- *
- * <p>
- * An example might be the bytecode for the following sequence.
- * <code><pre>
- * results[10]++;
- return
- * </pre></code>
- *
- * Which results in the following bytecode
- * <code><pre>
- 0: aload_0 // reference through 'this' to get
- 1: getfield // field 'results' which is an array of int
- 4: bipush 10 // push the array index
- 6: dup2 // dreaded dup2 we'll come back here
- 7: iaload // ignore for the moment.
- 8: iconst_1
- 9: iadd
- 10: iastore
- 11: return
- * </pre></code>
- *
- * First we need to know what the stack will look like before the dup2 is encountered.
- * Using our folding technique we represent the first two instructions inside ()
- *
- * <pre><code>
- getfield (aload_0 // result in the array field reference on stack
- bipush 10 // the array index
- dup2 // dreaded dup2 we'll come back here
- * </code></pre>
- *
- * The <code>dup2</code> essentially copies the top two elements on the stack. So we emulate this by replacing the dup2 with clones of the instructions which would reinstate the same stack state.
- * <p>
- * So after the <code>dup2</code> transform we end up with:-
- * <pre><code>
- getfield (aload_0) // result in the array field reference on stack
- bipush 10 // the array index
- {getfield (aload_0)} // result in the array field reference on stack
- {bipush 10} // the array index
- * </code></pre>
- *
- * So carrying on lets look at the <code>iaload</code> which consumes two operands (the index and the array field reference) and creates one (the result of an array access)
- *
- * <pre><code>
- getfield (aload_0) // result in the array field reference on stack
- bipush 10 // the array index
- {getfield (aload_0)} // result in the array field reference on stack
- {bipush 10} // the array index
- iaload
- * </code></pre>
- *
- * So we now have
- *
- * <pre><code>
- getfield (aload_0) // result in the array field reference on stack
- bipush 10 // the array index
- iaload ({getfield(aload_0), {bipush 10}) // results in the array element on the stack
- iconst
- iadd
- * </code></pre>
- *
- * And if you are following along the <code>iadd</code> will fold the previous two stack entries essentially pushing the result of
- * <code>results[10]+1<code> on the stack.
- *
- * <pre><code>
- getfield (aload_0) // result in the array field reference on stack
- bipush 10 // the array index
- iadd (iaload ({getfield(aload_0), {bipush 10}, iconst_1) // push of results[10]+1
- * </code></pre>
- * Then the final <code>istore</code> instruction which consumes 3 stack operands (the field array reference, the index and the value to assign).
- *
- * <p>
- * Which results in
- * <pre><code>
- istore (getfield (aload_0), bipush 10, iadd (iaload ({getfield(aload_0), {bipush 10}, iconst_1)) // results[10] = results[10+1]
- * </code></pre>
- *
- * Where <code>results[10] = results[10+1]<code> is the long-hand form of the <code>results[10]++</code>
- * and will be transformed by one of the 'inc' transforms to the more familiar form a little later.

+ * DUP family of instructions break our stack unwind model (whereby we treat instructions like the oeprands they create/consume).
+ *
+ * <p>
+ * Here we replace DUP style instructions with a 'mock' instruction which 'clones' the effect of the instruction. This would be invalid to execute but is useful
+ * to replace the DUP with a 'pattern' which it simulates. This allows us to later apply transforms to represent the original code.
+ *
+ * <p>
+ * An example might be the bytecode for the following sequence.
+ * <code><pre>
+ * results[10]++;
+ return
+ * </pre></code>
+ *
+ * Which results in the following bytecode
+ * <code><pre>
+ 0: aload_0 // reference through 'this' to get
+ 1: getfield // field 'results' which is an array of int
+ 4: bipush 10 // push the array index
+ 6: dup2 // dreaded dup2 we'll come back here
+ 7: iaload // ignore for the moment.
+ 8: iconst_1
+ 9: iadd
+ 10: iastore
+ 11: return
+ * </pre></code>
+ *
+ * First we need to know what the stack will look like before the dup2 is encountered.
+ * Using our folding technique we represent the first two instructions inside ()
+ *
+ * <pre><code>
+ getfield (aload_0 // result in the array field reference on stack
+ bipush 10 // the array index
+ dup2 // dreaded dup2 we'll come back here
+ * </code></pre>
+ *
+ * The <code>dup2</code> essentially copies the top two elements on the stack. So we emulate this by replacing the dup2 with clones of the instructions which would reinstate the same stack state.
+ * <p>
+ * So after the <code>dup2</code> transform we end up with:-
+ * <pre><code>
+ getfield (aload_0) // result in the array field reference on stack
+ bipush 10 // the array index
+ {getfield (aload_0)} // result in the array field reference on stack
+ {bipush 10} // the array index
+ * </code></pre>
+ *
+ * So carrying on lets look at the <code>iaload</code> which consumes two operands (the index and the array field reference) and creates one (the result of an array access)
+ *
+ * <pre><code>
+ getfield (aload_0) // result in the array field reference on stack
+ bipush 10 // the array index
+ {getfield (aload_0)} // result in the array field reference on stack
+ {bipush 10} // the array index
+ iaload
+ * </code></pre>
+ *
+ * So we now have
+ *
+ * <pre><code>
+ getfield (aload_0) // result in the array field reference on stack
+ bipush 10 // the array index
+ iaload ({getfield(aload_0), {bipush 10}) // results in the array element on the stack
+ iconst
+ iadd
+ * </code></pre>
+ *
+ * And if you are following along the <code>iadd</code> will fold the previous two stack entries essentially pushing the result of
+ * <code>results[10]+1<code> on the stack.
+ *
+ * <pre><code>
+ getfield (aload_0) // result in the array field reference on stack
+ bipush 10 // the array index
+ iadd (iaload ({getfield(aload_0), {bipush 10}, iconst_1) // push of results[10]+1
+ * </code></pre>
+ * Then the final <code>istore</code> instruction which consumes 3 stack operands (the field array reference, the index and the value to assign).
+ *
+ * <p>
+ * Which results in
+ * <pre><code>
+ istore (getfield (aload_0), bipush 10, iadd (iaload ({getfield(aload_0), {bipush 10}, iconst_1)) // results[10] = results[10+1]
+ * </code></pre>
+ *
+ * Where <code>results[10] = results[10+1]<code> is the long-hand form of the <code>results[10]++</code>
+ * and will be transformed by one of the 'inc' transforms to the more familiar form a little later.
