% ShearImage() creates a new image that is a shear_image copy of an existing
% one. Shearing slides one edge of an image along the X or Y axis, creating
% a parallelogram. An X direction shear slides an edge along the X axis,
% while a Y direction shear slides an edge along the Y axis. The amount of
% the shear is controlled by a shear angle. For X direction shears, x_shear
% is measured relative to the Y axis, and similarly, for Y direction shears
% y_shear is measured relative to the X axis. Empty triangles left over from
% shearing the image are filled with the background color defined by member
% 'background_color' of the image.. ShearImage() allocates the memory
% necessary for the new Image structure and returns a pointer to the new image.

% ShearRotateImage() creates a new image that is a rotated copy of an existing
% one. Positive angles rotate counter-clockwise (right-hand rule), while
% negative angles rotate clockwise. Rotated images are usually larger than
% the originals and have 'empty' triangular corners. X axis. Empty
% triangles left over from shearing the image are filled with the background
% color defined by member 'background_color' of the image. ShearRotateImage
% allocates the memory necessary for the new Image structure and returns a
% pointer to the new image.
%
% ShearRotateImage() is based on the paper "A Fast Algorithm for General
% Raster Rotatation" by Alan W. Paeth. ShearRotateImage is adapted from a
% similar method based on the Paeth paper written by Michael Halle of the
% Spatial Imaging Group, MIT Media Lab.
%
% The format of the ShearRotateImage method is:
%
% Image *ShearRotateImage(const Image *image,const double degrees,
% ExceptionInfo *exception)
%
% A description of each parameter follows.
%
% o image: the image.
%
% o degrees: Specifies the number of degrees to rotate the image.
%
% o exception: return any errors or warnings in this structure.

/// certain names, for example) and for performance, since name
/// lookup is often a bottleneck in the compilation of C++. Name
/// lookup criteria is specified via the LookupCriteria enumeration.
///
/// The results of name lookup can vary based on the kind of name
/// lookup performed, the current language, and the translation
/// unit. In C, for example, name lookup will either return nothing
/// (no entity found) or a single declaration. In C++, name lookup
/// can additionally refer to a set of overloaded functions or

% FloodfillPaintImage() changes the color value of any pixel that matches
% target and is an immediate neighbor. If the method FillToBorderMethod is
% specified, the color value is changed for any neighbor pixel that does not
% match the bordercolor member of image.
%
% By default target must match a particular pixel color exactly.
% However, in many cases two colors may differ by a small amount. The
% fuzz member of image defines how much tolerance is acceptable to
% consider two colors as the same. For example, set fuzz to 10 and the
% color red at intensities of 100 and 102 respectively are now
% interpreted as the same color for the purposes of the floodfill.
%
% The format of the FloodfillPaintImage method is:
%
% MagickBooleanType FloodfillPaintImage(Image *image,
% const ChannelType channel,const DrawInfo *draw_info,
% const MagickPixelPacket target,const ssize_t x_offset,
% const ssize_t y_offset,const MagickBooleanType invert)
%
% A description of each parameter follows:
%
% o image: the image.
%
% o channel: the channel(s).
%
% o draw_info: the draw info.
%
% o target: the RGB value of the target color.
%
% o x_offset,y_offset: the starting location of the operation.
%
% o invert: paint any pixel that does not match the target color.

/// certain names, for example) and for performance, since name
/// lookup is often a bottleneck in the compilation of C++. Name
/// lookup criteria is specified via the LookupCriteria enumeration.
///
/// The results of name lookup can vary based on the kind of name
/// lookup performed, the current language, and the translation
/// unit. In C, for example, name lookup will either return nothing
/// (no entity found) or a single declaration. In C++, name lookup
/// can additionally refer to a set of overloaded functions or

/* The parser. */
/* Overview
--------
A cp_parser parses the token stream as specified by the C++
grammar. Its job is purely parsing, not semantic analysis. For
example, the parser breaks the token stream into declarators,
expressions, statements, and other similar syntactic constructs.
It does not check that the types of the expressions on either side
of an assignment-statement are compatible, or that a function is
not declared with a parameter of type `void'.
The parser invokes routines elsewhere in the compiler to perform
semantic analysis and to build up the abstract syntax tree for the
code processed.
The parser (and the template instantiation code, which is, in a
way, a close relative of parsing) are the only parts of the
compiler that should be calling push_scope and pop_scope, or
related functions. The parser (and template instantiation code)
keeps track of what scope is presently active; everything else
should simply honor that. (The code that generates static
initializers may also need to set the scope, in order to check
access control correctly when emitting the initializers.)
Methodology
-----------
The parser is of the standard recursive-descent variety. Upcoming
tokens in the token stream are examined in order to determine which
production to use when parsing a non-terminal. Some C++ constructs
require arbitrary look ahead to disambiguate. For example, it is
impossible, in the general case, to tell whether a statement is an
expression or declaration without scanning the entire statement.
Therefore, the parser is capable of "parsing tentatively." When the
parser is not sure what construct comes next, it enters this mode.
Then, while we attempt to parse the construct, the parser queues up
error messages, rather than issuing them immediately, and saves the
tokens it consumes. If the construct is parsed successfully, the
parser "commits", i.e., it issues any queued error messages and
the tokens that were being preserved are permanently discarded.
If, however, the construct is not parsed successfully, the parser
rolls back its state completely so that it can resume parsing using
a different alternative.
Future Improvements
-------------------
The performance of the parser could probably be improved substantially.
We could often eliminate the need to parse tentatively by looking ahead
a little bit. In some places, this approach might not entirely eliminate
the need to parse tentatively, but it might still speed up the average
case. */

A defect report has been filed about this issue.
A conversion-function-id cannot be a template name because they cannot
be part of a template-id. In fact, looking at this code:
a.operator K<int>()
the conversion-function-id is "operator K<int>", and K<int> is a type-id.
It is impossible to call a templated conversion-function-id with an
explicit argument list, since the only allowed template parameter is
the type to which it is converting.
If TEMPLATE_KEYWORD_P is true, then we have just seen the
`template' keyword, in a construction like:
T::template f<3>()
In that case `f' is taken to be a template-name, even though there
is no way of knowing for sure.
Returns the TEMPLATE_DECL for the template, or an OVERLOAD if the
name refers to a set of overloaded functions, at least one of which
is a template, or an IDENTIFIER_NODE with the name of the template,

the `struct S' in the body of `f' is the same `struct S' as in
the global scope; the existing definition is used. However, if
there were no global declaration, this would introduce a new
local class named `S'.
An exception to this rule applies to the following code:
namespace N { struct S; }
Here, the elaborated-type-specifier names a new type
unconditionally; even if there is already an `S' in the
containing scope this declaration names a new type.
This exception only applies if the elaborated-type-specifier
forms the complete declaration:
[class.name]
A declaration consisting solely of `class-key identifier ;' is
either a redeclaration of the name in the current scope or a
forward declaration of the identifier as a class name. It
introduces the name into the current scope.
We are in this situation precisely when the next token is a `;'.
An exception to the exception is that a `friend' declaration does
*not* name a new type; i.e., given:
struct S { friend struct T; };
`T' is not a new type in the scope of `S'.
Also, `new struct S' or `sizeof (struct S)' never results in the

detect constructor, destructor or conversion operators. It is set

test for >0, but internally the negative value is used.

a decl-specifier-seq unless it declares a constructor, destructor,
or conversion. It might seem that we could check this condition in
semantic analysis, rather than parsing, but that makes it difficult
to handle something like `f()'. We want to notice that there are
no decl-specifiers, and therefore realize that this is an

real_t ubvec, idx_t *options, idx_t *objval, idx_t *part)
nvtxs: The number of vertices in the graph.
ncon: The number of balancing constraints. It should be at least 1.
xadj, adjncy: The adjacency structure of the graph as described in Section 5.5.
vwgt (NULL): The weights of the vertices as described in Section 5.5.
vsize (NULL): The size of the vertices for computing the total communication volume as described in Section 5.7.
adjwgt (NULL): The weights of the edges as described in Section 5.5.
nparts The number of parts to partition the graph.
tpwgts (NULL): This is an array of size npartsncon that specifies the desired weight for each partition and constraint.
The target partition weight for the ith partition and jth constraint is specified at tpwgts[i*ncon+j]
(the numbering for both partitions and constraints starts from 0). For each constraint, the sum of the
tpwgts[] entries must be 1.0 (i.e., \Sum_i tpwgts[i*ncon + j] = 1:0).
A NULL value can be passed to indicate that the graph should be equally divided among the partitions.
ubvec (NULL): This is an array of size ncon that specifies the allowed load imbalance tolerance for each constraint.
For the ith partition and jth constraint the allowed weight is the ubvec[j]*tpwgts[i*ncon+j] fraction
of the jth’s constraint total weight. The load imbalances must be greater than 1.0.
A NULL value can be passed indicating that the load imbalance tolerance for each constraint should
be 1.001 (for ncon=1) or 1.01 (for ncon<1).
options (NULL):
This is the array of options as described in Section 5.4.
The following options are valid for METIS PartGraphRecursive:
METIS_OPTION_CTYPE, METIS_OPTION_IPTYPE, METIS_OPTION_RTYPE,
METIS_OPTION_NO2HOP, METIS_OPTION_NCUTS, METIS_OPTION_NITER,
METIS_OPTION_SEED, METIS_OPTION_UFACTOR, METIS_OPTION_NUMBERING,
METIS_OPTION_DBGLVL
The following options are valid for METIS PartGraphKway:
METIS_OPTION_OBJTYPE, METIS_OPTION_CTYPE, METIS_OPTION_IPTYPE,
METIS_OPTION_RTYPE, METIS_OPTION_NO2HOP, METIS_OPTION_NCUTS,
METIS_OPTION_NITER, METIS_OPTION_UFACTOR, METIS_OPTION_MINCONN,
METIS_OPTION_CONTIG, METIS_OPTION_SEED, METIS_OPTION_NUMBERING,
METIS_OPTION_DBGLVL
objval: Upon successful completion, this variable stores the edge-cut or the total communication volume of
the partitioning solution. The value returned depends on the partitioning’s objective function.
part: This is a vector of size nvtxs that upon successful completion stores the partition vector of the graph.
The numbering of this vector starts from either 0 or 1, depending on the value of
options[METIS OPTION NUMBERING].
Returns
METIS OK Indicates that the function returned normally.
METIS ERROR INPUT Indicates an input error.
METIS ERROR MEMORY Indicates that it could not allocate the required memory.
METIS ERROR Indicates some other type of error.

Usage of language-independent fields in a language-dependent manner:
TYPE_ALIAS_SET
This field is used by TYPENAME_TYPEs, TEMPLATE_TYPE_PARMs, and so
forth as a substitute for the mark bits provided in `lang_type'.
At present, only the six low-order bits are used.
TYPE_LANG_SLOT_1
For an ENUMERAL_TYPE, this is ENUM_TEMPLATE_INFO.
For a FUNCTION_TYPE or METHOD_TYPE, this is TYPE_RAISES_EXCEPTIONS
BINFO_VIRTUALS
For a binfo, this is a TREE_LIST. There is an entry for each
virtual function declared either in BINFO or its direct and
indirect primary bases.
The BV_DELTA of each node gives the amount by which to adjust the
`this' pointer when calling the function. If the method is an
overridden version of a base class method, then it is assumed
that, prior to adjustment, the this pointer points to an object
of the base class.
The BV_VCALL_INDEX of each node, if non-NULL, gives the vtable
index of the vcall offset for this entry.
The BV_FN is the declaration for the virtual function itself.
If BV_LOST_PRIMARY is set, it means that this entry is for a lost
primary virtual base and can be left null in the vtable.
BINFO_VTABLE
This is an expression with POINTER_TYPE that gives the value
to which the vptr should be initialized. Use get_vtbl_decl_for_binfo
to extract the VAR_DECL for the complete vtable.
DECL_VINDEX
This field is NULL for a non-virtual function. For a virtual
function, it is eventually set to an INTEGER_CST indicating the
index in the vtable at which this function can be found. When
a virtual function is declared, but before it is known what
function is overridden, this field is the error_mark_node.
Temporarily, it may be set to a TREE_LIST whose TREE_VALUE is
the virtual function this one overrides, and whose TREE_CHAIN is
the old DECL_VINDEX. */

of thousands) of template parameter types in a compilation, and
there's no need for this additional information in that case.
Therefore, we now use this data structure only for class types.
In the past, it was thought that there would be relatively few
class types. However, in the presence of heavy use of templates,
many (i.e., thousands) of classes can easily be generated.
Therefore, we should endeavor to keep the size of this structure to
a minimum. */

/* A thunk is a stub function.
A thunk is an alternate entry point for an ordinary FUNCTION_DECL.
The address of the ordinary FUNCTION_DECL is given by the
DECL_INITIAL, which is always an ADDR_EXPR whose operand is a
FUNCTION_DECL. The job of the thunk is to either adjust the this
pointer before transferring control to the FUNCTION_DECL, or call
FUNCTION_DECL and then adjust the result value. Note, the result
pointer adjusting thunk must perform a call to the thunked
function, (or be implemented via passing some invisible parameter
to the thunked function, which is modified to perform the
adjustment just before returning).
A thunk may perform either, or both, of the following operations:
o Adjust the this or result pointer by a constant offset.
o Adjust the this or result pointer by looking up a vcall or vbase offset
in the vtable.
A this pointer adjusting thunk converts from a base to a derived
class, and hence adds the offsets. A result pointer adjusting thunk
converts from a derived class to a base, and hence subtracts the
offsets. If both operations are performed, then the constant
adjustment is performed first for this pointer adjustment and last
for the result pointer adjustment.
The constant adjustment is given by THUNK_FIXED_OFFSET. If the
vcall or vbase offset is required, THUNK_VIRTUAL_OFFSET is
used. For this pointer adjusting thunks, it is the vcall offset
into the vtable. For result pointer adjusting thunks it is the
binfo of the virtual base to convert to. Use that binfo's vbase
offset.
It is possible to have equivalent covariant thunks. These are
distinct virtual covariant thunks whose vbase offsets happen to
have the same value. THUNK_ALIAS is used to pick one as the
canonical thunk, which will get all the this pointer adjusting
thunks attached to it. */

virtual adjust. (The vptr is always located at offset zero from
the this or result pointer.) (If the covariant type is within the

/* This pass tries to distribute iterations of loops into several threads.
The implementation is straightforward -- for each loop we test whether its
iterations are independent, and if it is the case (and some additional
conditions regarding profitability and correctness are satisfied), we
add GIMPLE_OMP_PARALLEL and GIMPLE_OMP_FOR codes and let omp expansion
machinery do its job.
The most of the complexity is in bringing the code into shape expected
by the omp expanders:
-- for GIMPLE_OMP_FOR, ensuring that the loop has only one induction
variable and that the exit test is at the start of the loop body
-- for GIMPLE_OMP_PARALLEL, replacing the references to local addressable
variables by accesses through pointers, and breaking up ssa chains
by storing the values incoming to the parallelized loop to a structure
passed to the new function as an argument (something similar is done
in omp gimplification, unfortunately only a small part of the code
can be shared).
TODO:
-- if there are several parallelizable loops in a function, it may be
possible to generate the threads just once (using synchronization to
ensure that cross-loop dependences are obeyed).
-- handling of common reduction patterns for outer loops.
