///
/// An OpenMP canonical loop is a for-statement or range-based for-statement
/// with additional requirements that ensure that the number of iterations is
/// known before entering the loop and allow skipping to an arbitrary iteration.
/// The OMPCanonicalLoop AST node wraps a ForStmt or CXXForRangeStmt that is
/// known to fulfill OpenMP's canonical loop requirements because of being
/// associated to an OMPLoopBasedDirective. That is, the general structure is:
///
/// OMPLoopBasedDirective
/// [`- CapturedStmt ]
/// [ `- CapturedDecl]
/// ` OMPCanonicalLoop
/// `- ForStmt/CXXForRangeStmt
/// `- Stmt
///
/// One or multiple CapturedStmt/CapturedDecl pairs may be inserted by some
/// directives such as OMPParallelForDirective, but others do not need them
/// (such as OMPTileDirective). In The OMPCanonicalLoop and
/// ForStmt/CXXForRangeStmt pair is repeated for loop associated with the
/// directive. A OMPCanonicalLoop must not appear in the AST unless associated
/// with a OMPLoopBasedDirective. In an imperfectly nested loop nest, the
/// OMPCanonicalLoop may also be wrapped in a CompoundStmt:
///
/// [...]
/// ` OMPCanonicalLoop
/// `- ForStmt/CXXForRangeStmt
/// `- CompoundStmt
/// |- Leading in-between code (if any)
/// |- OMPCanonicalLoop
/// | `- ForStmt/CXXForRangeStmt
/// | `- ...
/// `- Trailing in-between code (if any)
///
/// The leading/trailing in-between code must not itself be a OMPCanonicalLoop
/// to avoid confusion which loop belongs to the nesting.
///
/// There are three different kinds of iteration variables for different
/// purposes:
/// * Loop user variable: The user-accessible variable with different value for
/// each iteration.
/// * Loop iteration variable: The variable used to identify a loop iteration;
/// for range-based for-statement, this is the hidden iterator '__begin'. For
/// other loops, it is identical to the loop user variable. Must be a
/// random-access iterator, pointer or integer type.
/// * Logical iteration counter: Normalized loop counter starting at 0 and
/// incrementing by one at each iteration. Allows abstracting over the type
/// of the loop iteration variable and is always an unsigned integer type
/// appropriate to represent the range of the loop iteration variable. Its
/// value corresponds to the logical iteration number in the OpenMP
/// specification.
///
/// This AST node provides two captured statements:
/// * The distance function which computes the number of iterations.
/// * The loop user variable function that computes the loop user variable when
/// given a logical iteration number.
///
/// These captured statements provide the link between C/C++ semantics and the
/// logical iteration counters used by the OpenMPIRBuilder which is
/// language-agnostic and therefore does not know e.g. how to advance a
/// random-access iterator. The OpenMPIRBuilder will use this information to
/// apply simd, workshare-loop, distribute, taskloop and loop directives to the
/// loop. For compatibility with the non-OpenMPIRBuilder codegen path, an
/// OMPCanonicalLoop can itself also be wrapped into the CapturedStmts of an
/// OMPLoopDirective and skipped when searching for the associated syntactical
/// loop.
///
/// Example:
/// <code>
/// std::vector<std::string> Container{1,2,3};
/// for (std::string Str : Container)
/// Body(Str);
/// </code>
/// which is syntactic sugar for approximately:
/// <code>
/// auto &&__range = Container;
/// auto __begin = std::begin(__range);
/// auto __end = std::end(__range);
/// for (; __begin != __end; ++__begin) {
/// std::String Str = *__begin;
/// Body(Str);
/// }
/// </code>
/// In this example, the loop user variable is `Str`, the loop iteration
/// variable is `__begin` of type `std::vector<std::string>::iterator` and the
/// logical iteration number type is `size_t` (unsigned version of
/// `std::vector<std::string>::iterator::difference_type` aka `ptrdiff_t`).
/// Therefore, the distance function will be
/// <code>
/// [&](size_t &Result) { Result = __end - __begin; }
/// </code>
/// and the loop variable function is
/// <code>
/// [&,__begin](std::vector<std::string>::iterator &Result, size_t Logical) {
/// Result = __begin + Logical;
/// }
/// </code>
/// The variable `__begin`, aka the loop iteration variable, is captured by
/// value because it is modified in the loop body, but both functions require
/// the initial value. The OpenMP specification explicitly leaves unspecified
/// when the loop expressions are evaluated such that a capture by reference is
/// sufficient.

/* This page contains routines to unshare tree nodes, i.e. to duplicate tree
nodes that are referenced more than once in GENERIC functions. This is
necessary because gimplification (translation into GIMPLE) is performed
by modifying tree nodes in-place, so gimplication of a shared node in a
first context could generate an invalid GIMPLE form in a second context.
This is achieved with a simple mark/copy/unmark algorithm that walks the
GENERIC representation top-down, marks nodes with TREE_VISITED the first
time it encounters them, duplicates them if they already have TREE_VISITED
set, and finally removes the TREE_VISITED marks it has set.
The algorithm works only at the function level, i.e. it generates a GENERIC
representation of a function with no nodes shared within the function when
passed a GENERIC function (except for nodes that are allowed to be shared).
At the global level, it is also necessary to unshare tree nodes that are
referenced in more than one function, for the same aforementioned reason.
This requires some cooperation from the front-end. There are 2 strategies:
1. Manual unsharing. The front-end needs to call unshare_expr on every
expression that might end up being shared across functions.
2. Deep unsharing. This is an extension of regular unsharing. Instead
of calling unshare_expr on expressions that might be shared across
functions, the front-end pre-marks them with TREE_VISITED. This will
ensure that they are unshared on the first reference within functions
when the regular unsharing algorithm runs. The counterpart is that
this algorithm must look deeper than for manual unsharing, which is
specified by LANG_HOOKS_DEEP_UNSHARING.
If there are only few specific cases of node sharing across functions, it is
probably easier for a front-end to unshare the expressions manually. On the
contrary, if the expressions generated at the global level are as widespread
as expressions generated within functions, deep unsharing is very likely the
way to go. */

/* Convert the GENERIC expression tree *EXPR_P to GIMPLE. If the
expression produces a value to be used as an operand inside a GIMPLE
statement, the value will be stored back in *EXPR_P. This value will
be a tree of class tcc_declaration, tcc_constant, tcc_reference or
an SSA_NAME. The corresponding sequence of GIMPLE statements is
emitted in PRE_P and POST_P.
Additionally, this process may overwrite parts of the input
expression during gimplification. Ideally, it should be
possible to do non-destructive gimplification.
EXPR_P points to the GENERIC expression to convert to GIMPLE. If
the expression needs to evaluate to a value to be used as
an operand in a GIMPLE statement, this value will be stored in
*EXPR_P on exit. This happens when the caller specifies one
of fb_lvalue or fb_rvalue fallback flags.
PRE_P will contain the sequence of GIMPLE statements corresponding
to the evaluation of EXPR and all the side-effects that must
be executed before the main expression. On exit, the last
statement of PRE_P is the core statement being gimplified. For
instance, when gimplifying 'if (++a)' the last statement in
PRE_P will be 'if (t.1)' where t.1 is the result of
pre-incrementing 'a'.
POST_P will contain the sequence of GIMPLE statements corresponding
to the evaluation of all the side-effects that must be executed
after the main expression. If this is NULL, the post
side-effects are stored at the end of PRE_P.
The reason why the output is split in two is to handle post
side-effects explicitly. In some cases, an expression may have
inner and outer post side-effects which need to be emitted in
an order different from the one given by the recursive
traversal. For instance, for the expression (*p--)++ the post
side-effects of '--' must actually occur *after* the post
side-effects of '++'. However, gimplification will first visit
the inner expression, so if a separate POST sequence was not
used, the resulting sequence would be:
1 t.1 = *p
2 p = p - 1
3 t.2 = t.1 + 1
4 *p = t.2
However, the post-decrement operation in line #2 must not be
evaluated until after the store to *p at line #4, so the
correct sequence should be:
1 t.1 = *p
2 t.2 = t.1 + 1
3 *p = t.2
4 p = p - 1
So, by specifying a separate post queue, it is possible
to emit the post side-effects in the correct order.
If POST_P is NULL, an internal queue will be used. Before
returning to the caller, the sequence POST_P is appended to
the main output sequence PRE_P.
GIMPLE_TEST_F points to a function that takes a tree T and
returns nonzero if T is in the GIMPLE form requested by the
caller. The GIMPLE predicates are in gimple.c.
FALLBACK tells the function what sort of a temporary we want if
gimplification cannot produce an expression that complies with
GIMPLE_TEST_F.
fb_none means that no temporary should be generated
fb_rvalue means that an rvalue is OK to generate
fb_lvalue means that an lvalue is OK to generate
fb_either means that either is OK, but an lvalue is preferable.
fb_mayfail means that gimplification may fail (in which case
GS_ERROR will be returned)
The return value is either GS_ERROR or GS_ALL_DONE, since this
function iterates until EXPR is completely gimplified or an error
occurs. */

% ChannelFxImage() applies a channel expression to the specified image. The
% expression consists of one or more channels, either mnemonic or numeric (e.g.
% red, 1), separated by actions as follows:
%
% <=> exchange two channels (e.g. red<=>blue)
% => copy one channel to another channel (e.g. red=>green)
% = assign a constant value to a channel (e.g. red=50%)
% , write new image channels in the specified order (e.g. red, green)
% | add a new output image for the next set of channel operations
% ; move to the next input image for the source of channel data
%
% For example, to create 3 grayscale images from the red, green, and blue
% channels of an image, use:
%
% -channel-fx "red; green; blue"
%
% A channel without an operation symbol implies separate (i.e, semicolon).
%
% The format of the ChannelFxImage method is:
%
% Image *ChannelFxImage(const Image *image,const char *expression,
% ExceptionInfo *exception)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o expression: A channel expression.
%
% o exception: return any errors or warnings in this structure.

This function does not handle __extension__; that is handled in its
callers. ??? Following the old parser, __extension__ may start
external declarations, declarations in functions and declarations
at the start of "for" loops, but not old-style parameter
declarations.
C99 requires declaration specifiers in a function definition; the
absence is diagnosed through the diagnosis of implicit int. In GNU
C we also allow but diagnose declarations without declaration
specifiers, but only at top level (elsewhere they conflict with
other syntax).
In Objective-C, declarations of the looping variable in a foreach
statement are exceptionally terminated by 'in' (for example, 'for
(NSObject *object in array) { ... }').

declarator, they could start a parenthesized declarator or a
parameter list. To tell which, the open parenthesis and any
following attributes must be read. If a declaration specifier
follows, then it is a parameter list; if the specifier is a
typedef name, there might be an ambiguity about redeclaring it,
which is resolved in the direction of treating it as a typedef
name. If a close parenthesis follows, it is also an empty
parameter list, as the syntax does not permit empty abstract
declarators. Otherwise, it is a parenthesized declarator (in
which case the analysis may be repeated inside it, recursively).
??? There is an ambiguity in a parameter declaration "int
(__attribute__((foo)) x)", where x is not a typedef name: it
could be an abstract declarator for a function, or declare x with
parentheses. The proper resolution of this ambiguity needs
documenting. At present we follow an accident of the old
parser's implementation, whereby the first parameter must have
some declaration specifiers other than just attributes. Thus as
a parameter declaration it is treated as a parenthesized
parameter named x, and as an abstract declarator it is
rejected.
??? Also following the old parser, attributes inside an empty
parameter list are ignored, making it a list not yielding a
prototype, rather than giving an error or making it have one
parameter with implicit type int.

redeclared in declarators, but not Objective-C class names. */

Allowing the mixing of declarations and code is new in C99. The
GNU syntax also permits (not shown above) labels at the end of
compound statements, which yield an error. We don't allow labels
on declarations; this might seem like a natural extension, but
there would be a conflict between attributes on the label and
prefix attributes on the declaration. ??? The syntax follows the
old parser in requiring something after label declarations.
Although they are erroneous if the labels declared aren't defined,
is it useful for the syntax to be this way?

for-statement:
for ( expression[opt] ; expression[opt] ; expression[opt] ) statement
for ( nested-declaration expression[opt] ; expression[opt] ) statement
The form with a declaration is new in C99.
??? In accordance with the old parser, the declaration may be a
nested function, which is then rejected in check_for_loop_decls,
but does it make any sense for this to be included in the grammar?
Note in particular that the nested function does not include a
trailing ';', whereas the "declaration" production includes one.
Also, can we reject bad declarations earlier and cheaper than
check_for_loop_decls?
In Objective-C, there are two additional variants:
foreach-statement:
for ( expression in expresssion ) statement
for ( declaration in expression ) statement
This is inconsistent with C, because the second variant is allowed
even if c99 is not enabled.
The rest of the comment documents these Objective-C foreach-statement.
Here is the canonical example of the first variant:
for (object in array) { do something with object }
we call the first expression ("object") the "object_expression" and
the second expression ("array") the "collection_expression".
object_expression must be an lvalue of type "id" (a generic Objective-C
object) because the loop works by assigning to object_expression the
various objects from the collection_expression. collection_expression
must evaluate to something of type "id" which responds to the method
countByEnumeratingWithState:objects:count:.
The canonical example of the second variant is:
for (id object in array) { do something with object }
which is completely equivalent to
{
id object;
for (object in array) { do something with object }
}
Note that initizializing 'object' in some way (eg, "for ((object =
xxx) in array) { do something with object }") is possibly
technically valid, but completely pointless as 'object' will be
assigned to something else as soon as the loop starts. We should
most likely reject it (TODO).
The beginning of the Objective-C foreach-statement looks exactly
like the beginning of the for-statement, and we can tell it is a
foreach-statement only because the initial declaration or
expression is terminated by 'in' instead of ';'.
IF_P is used to track whether there's a (possibly labeled) if statement
which is not enclosed in braces and has an else clause. This is used to
implement -Wparentheses. */

\param n Number of data points

\param k Number of clusters
\param data Data points, in row-major order. This vector must have
size n * d, and since it's in row-major order, data point x occupies
positions [x * d, (x + 1) * d) in the vector. The vector is passed
by reference since it is shared with the caller and not copied.
\param labels Cluster labels. This vector has size n.
The vector is passed by reference since it is shared with the caller
and not copied.
\param centroids Centroid locations, in row-major order. This
vector must have size k * d, and since it's in row-major order,
centroid x occupies positions [x * d, (x + 1) * d) in the
vector. The vector is passed by reference since it is shared
with the caller and not copied.
\param threshold This controls early termination of the kmeans
iterations. If the ratio of points being reassigned to a different
centroid is less than the threshold, than the iterations are
terminated. Defaults to 1e-3.
\param max_iterations Maximum number of iterations to run
\return The number of iterations actually performed.

% ClutImage() replaces each color value in the given image, by using it as an
% index to lookup a replacement color value in a Color Look UP Table in the
% form of an image. The values are extracted along a diagonal of the CLUT
% image so either a horizontal or vertial gradient image can be used.
%
% Typically this is used to either re-color a gray-scale image according to a
% color gradient in the CLUT image, or to perform a freeform histogram
% (level) adjustment according to the (typically gray-scale) gradient in the
% CLUT image.
%
% When the 'channel' mask includes the matte/alpha transparency channel but
% one image has no such channel it is assumed that that image is a simple
% gray-scale image that will effect the alpha channel values, either for
% gray-scale coloring (with transparent or semi-transparent colors), or
% a histogram adjustment of existing alpha channel values. If both images
% have matte channels, direct and normal indexing is applied, which is rarely
% used.
%
% The format of the ClutImage method is:
%
% MagickBooleanType ClutImage(Image *image,Image *clut_image)
% MagickBooleanType ClutImageChannel(Image *image,
% const ChannelType channel,Image *clut_image)

% A description of each parameter follows:
%
% o image: the image, which is replaced by indexed CLUT values

% ContrastStretchImage() is a simple image enhancement technique that attempts
% to improve the contrast in an image by `stretching' the range of intensity
% values it contains to span a desired range of values. It differs from the
% more sophisticated histogram equalization in that it can only apply a
% linear scaling function to the image pixel values. As a result the
% `enhancement' is less harsh.
%
% The format of the ContrastStretchImage method is:
%
% MagickBooleanType ContrastStretchImage(Image *image,
% const char *levels)
% MagickBooleanType ContrastStretchImageChannel(Image *image,
% const size_t channel,const double black_point,
% const double white_point)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o channel: the channel.
%
% o black_point: the black point.
%
% o white_point: the white point.
%
% o levels: Specify the levels where the black and white points have the
% range of 0 to number-of-pixels (e.g. 1%, 10x90%, etc.).

% SigmoidalContrastImage() adjusts the contrast of an image with a non-linear
% sigmoidal contrast algorithm. Increase the contrast of the image using a
% sigmoidal transfer function without saturating highlights or shadows.
% Contrast indicates how much to increase the contrast (0 is none; 3 is
% typical; 20 is pushing it); mid-point indicates where midtones fall in the
% resultant image (0 is white; 50% is middle-gray; 100% is black). Set
% sharpen to MagickTrue to increase the image contrast otherwise the contrast
% is reduced.
%
% The format of the SigmoidalContrastImage method is:
%

% const MagickBooleanType sharpen,const char *levels)
% MagickBooleanType SigmoidalContrastImageChannel(Image *image,
% const ChannelType channel,const MagickBooleanType sharpen,
% const double contrast,const double midpoint)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o channel: the channel.
%
% o sharpen: Increase or decrease image contrast.
%
% o alpha: strength of the contrast, the larger the number the more
% 'threshold-like' it becomes.

* Sequential Mandelbrot program
*
* This program computes and displays all or part of the Mandelbrot
* set. By default, it examines all points in the complex plane
* that have both real and imaginary parts between -2 and 2.
* Command-line parameters allow zooming in on a specific part of
* this range.
*
* Usage:
* mandel [-i maxiter -c x0 y0 -s size -w windowsize]
* where
* maxiter denotes the maximum number of iterations at each point -- by default 1000
* x0, y0, and size specify the range to examine (a square
* centered at (x0 + iy0) of size 2*size by 2*size -- by default,
* a square of size 4 by 4 centered at the origin)
* windowsize denotes the size of the image (diplay window) to compute
*
* Input: none, except the optional command-line arguments
* Output: a graphical display as described in Wilkinson & Allen,
* displayed using the X Window system, plus text output to
* standard output showing the above parameters, plus execution
* time in seconds.
*
* Code based on the original code from Web site for Wilkinson and Allen's

% CompositeImageChannel() returns the second image composited onto the first
% at the specified offset, using the specified composite method.
%
% The format of the CompositeImageChannel method is:
%
% MagickBooleanType CompositeImage(Image *image,
% const CompositeOperator compose,Image *source_image,
% const ssize_t x_offset,const ssize_t y_offset)
% MagickBooleanType CompositeImageChannel(Image *image,
% const ChannelType channel,const CompositeOperator compose,
% Image *source_image,const ssize_t x_offset,const ssize_t y_offset)
%
% A description of each parameter follows:
%
% o image: the canvas image, modified by he composition
%
% o channel: the channel.
%
% o compose: This operator affects how the composite is applied to
% the image. The operators and how they are utilized are listed here
% http://www.w3.org/TR/SVG12/#compositing.
%
% o source_image: the composite (source) image.
%
% o x_offset: the column offset of the composited image.
%
% o y_offset: the row offset of the composited image.
%
% Extra Controls from Image meta-data in 'source_image' (artifacts)
%
% o "compose:args"
% A string containing extra numerical arguments for specific compose
% methods, generally expressed as a 'geometry' or a comma separated list
% of numbers.
%
% Compose methods needing such arguments include "BlendCompositeOp" and
% "DisplaceCompositeOp".
%
% o "compose:outside-overlay"
% Modify how the composition is to effect areas not directly covered
% by the 'source_image' at the offset given. Normally this is
% dependant on the 'compose' method, especially Duff-Porter methods.
%
% If set to "false" then disable all normal handling of pixels not
% covered by the source_image. Typically used for repeated tiling
% of the source_image by the calling API.
%
% Previous to IM v6.5.3-3 this was called "modify-outside-overlay"
%

/*
** Programmers notes on SVG specification.
**
** A Composition is defined by...
** Color Function : f(Sc,Dc) where Sc and Dc are the normizalized colors
** Blending areas : X = 1 for area of overlap ie: f(Sc,Dc)
** Y = 1 for source preserved
** Z = 1 for canvas preserved
**
** Conversion to transparency (then optimized)
** Dca' = f(Sc, Dc)*Sa*Da + Y*Sca*(1-Da) + Z*Dca*(1-Sa)
** Da' = X*Sa*Da + Y*Sa*(1-Da) + Z*Da*(1-Sa)
**
** Where...
** Sca = Sc*Sa normalized Source color divided by Source alpha
** Dca = Dc*Da normalized Dest color divided by Dest alpha
** Dc' = Dca'/Da' the desired color value for this channel.
**
** Da' in in the follow formula as 'gamma' The resulting alpla value.
**
**
** Most functions use a blending mode of over (X=1,Y=1,Z=1)
** this results in the following optimizations...
** gamma = Sa+Da-Sa*Da;
** gamma = 1 - QuantumScale*alpha * QuantumScale*beta;
** opacity = QuantumScale*alpha*beta; // over blend, optimized 1-Gamma
**
** The above SVG definitions also define that Mathematical Composition
** methods should use a 'Over' blending mode for Alpha Channel.
** It however was not applied for composition modes of 'Plus', 'Minus',
** the modulus versions of 'Add' and 'Subtract'.
**
**
** Mathematical operator changes to be applied from IM v6.7...
**
** 1/ Modulus modes 'Add' and 'Subtract' are obsoleted and renamed
** 'ModulusAdd' and 'ModulusSubtract' for clarity.
**
** 2/ All mathematical compositions work as per the SVG specification
** with regard to blending. This now includes 'ModulusAdd' and
** 'ModulusSubtract'.
**
** 3/ When the special channel flag 'sync' (syncronize channel updates)
** is turned off (enabled by default) then mathematical compositions are
** only performed on the channels specified, and are applied
** independantally of each other. In other words the mathematics is
** performed as 'pure' mathematical operations, rather than as image
** operations.

GAP Benchmark Suite
Kernel: Breadth-First Search (BFS)
Author: Scott Beamer
Will return parent array for a BFS traversal from a source vertex
This BFS implementation makes use of the Direction-Optimizing approach [1].
It uses the alpha and beta parameters to determine whether to switch search
directions. For representing the frontier, it uses a SlidingQueue for the
top-down approach and a Bitmap for the bottom-up approach. To reduce
false-sharing for the top-down approach, thread-local QueueBuffer's are used.
To save time computing the number of edges exiting the frontier, this
implementation precomputes the degrees in bulk at the beginning by storing
them in parent array as negative numbers. Thus the encoding of parent is:
parent[x] < 0 implies x is unvisited and parent[x] = -out_degree(x)
parent[x] >= 0 implies x been visited
