/// \name Name lookup
///
/// These routines provide name lookup that is used during semantic
/// analysis to resolve the various kinds of names (identifiers,
/// overloaded operator names, constructor names, etc.) into zero or
/// more declarations within a particular scope. The major entry
/// points are LookupName, which performs unqualified name lookup,
/// and LookupQualifiedName, which performs qualified name lookup.
///
/// All name lookup is performed based on some specific criteria,
/// which specify what names will be visible to name lookup and how
/// far name lookup should work. These criteria are important both
/// for capturing language semantics (certain lookups will ignore
/// 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
/// result in an ambiguity. All of the possible results of name
/// lookup are captured by the LookupResult class, which provides
/// the ability to distinguish among them.

// Dynamic wave flow routing functions.
//
// This module solves the dynamic wave flow routing equations using
// Picard Iterations (i.e., a method of successive approximations)
// to solve the explicit form of the continuity and momentum equations
// for conduits.
//
// Build 5.1.002:
// - Only non-ponded nodal surface area is saved for use in
// surcharge algorithm.
//
// Build 5.1.007:
// - Node losses added to node outflow variable instead of treated
// as a separate item when computing change in node flow volume.
//
// Build 5.1.008:
// - Module-specific constants moved here from project.c.
// - Support added for user-specified minimum variable time step.
// - Node crown elevations found here instead of in flowrout.c module.
// - OpenMP use to parallelize findLinkFlows() & findNodeDepths().
// - Bug in finding complete list of capacity limited links fixed.
//
// Build 5.1.011:
// - Added test for failed memory allocation.
// - Fixed illegal array index bug for Ideal Pumps.
//
// Build 5.1.013:
// - Include omp.h protected against lack of compiler support for OpenMP.
// - SurchargeMethod option used to decide how node surcharging is handled.
// - Storage nodes allowed to pressurize if their surcharge depth > 0.
// - Minimum flow needed to compute a Courant time step modified.
//
// Build 5.1.014:
// - updateNodeFlows() modified to subtract conduit evap. and seepage losses
// from downstream node inflow instead of upstream node outflow.
//
// Build 5.1.015:
// - Roll back the 5.1.014 change for conduit losses in updateNodeFlows().

taken. The atomic processing is smart enough to figure out when the
size of an object can utilize a lock-free version, and convert the
built-in call to the appropriate lock-free routine. The optimizers
will then dispose of any temps that are no longer required, and
lock-free implementations are utilized as long as there is target
support for the required size.

an __atomic_store is issued to perform the assignment rather than
the above loop.

* Thus, the worst-case performance is O(w * (|E| + |V|)), but performs better

HOG block-normalisation. For each cell, there are four 2x2 blocks

+---+---+---+
In the Dalal-Triggs implementation, one forms all possible 2x2 blocks
of cells, computes a descriptor vector for each by stacking the corresponding
2x2 HOG cells, and L2 normalizes (and truncates) the result.
Thus each HOG cell appears in four blocks. These are then decomposed
again to produce descriptors for each cell. Each descriptor is simply
the stacking of the portion of each block descriptor that arised
from that cell. This process result in a descriptor
of each cell which contains four copies of the original HOG,
with four different normalization factors.
@remark By stacking together the cell descriptors for a large retangular block
of cells, one effectively stacks together the block descriptors of
an equal number of blocks (except for the boundaries, for which
blocks are only partially included). Since blocks are L2 normalized
(up to truncation), this implies that the L2 norm of the resulting
vector is approximately equal to the area of the region.

// This container is an array that is capable of being appended to in an

// use cases currently present in OpenMC. Namely, it covers the scenario where
// multiple threads are appending to an array, but no threads are reading from
// or operating on it in any other way at the same time. Multiple threads can
// call the thread_safe_append() function concurrently and store data to the
// object at the index returned from thread_safe_append() safely, but no other
// operations are protected.

/**
* @class ResidualBasedEliminationBuilderAndSolverWithConstraints
* @ingroup KratosCore
* @brief Current class provides an implementation for standard builder and solving operations.
* @details The RHS is constituted by the unbalanced loads (residual)
* Degrees of freedom are reordered putting the restrained degrees of freedom at
* the end of the system ordered in reverse order with respect to the DofSet.
* Imposition of the dirichlet conditions is naturally dealt with as the residual already contains
* this information.
* Calculation of the reactions involves a cost very similiar to the calculation of the total residual
* The system is build in the following manner. A T matrix is assembled and constant vector g is assembled too. The T matrix contains the relations of all the dofs of the system, even the nodes with no master/slave relation. Then the size is n_total x n_red
* The relation u = T u_red
* Then:
* A_red = T^t A T
* b_red = T^t (b - A g)
* @todo There is a more efficient way to asemble the system, but more costly, which is the following. In this case T will be only a relation matrix between master and slave dofs. Then n_slave x n_master: us = T um + g
* Separating into independent dofs, master ans slave dofs:
* u = uu
* um
* us
* A = Auu Aum Aus
* Amu Amm Ams
* Asu Asm Ass
* b = bu
* bm
* bs
* Finally:
* A_red = Auu Aum + Aus T
* Amu + T^t Asu Amm + T^t Ams^t + Ams T + T^t Ass T
* b_red = bu - Aus g
* bm - Ams g
*
* This system requires extra care and is more complicated and requires to compute the blocks properly

* Header file for memory management utilities
*
* The abstract memory model has a Host (think CPU) and a Device (think GPU) and
* three basic types of memory management utilities:
*
* 1. Malloc(..., location)
* location=LOCATION_DEVICE - malloc memory on the device
* location=LOCATION_HOST - malloc memory on the host
* 2. MemCopy(..., method)
* method=HOST_TO_DEVICE - copy from host to device
* method=DEVICE_TO_HOST - copy from device to host
* method=DEVICE_TO_DEVICE - copy from device to device
* 3. SetExecutionMode
* location=LOCATION_DEVICE - execute on the device
* location=LOCATION_HOST - execute on the host
*
* Although the abstract model does not explicitly reflect a managed memory
* model (i.e., unified memory), it can support it. Here is a summary of how
* the abstract model would be mapped to specific hardware scenarios:
*
* Not using a device, not using managed memory
* Malloc(..., location)
* location=LOCATION_DEVICE - host malloc e.g., malloc
* location=LOCATION_HOST - host malloc e.g., malloc
* MemoryCopy(..., locTo,locFrom)
* locTo=LOCATION_HOST, locFrom=LOCATION_DEVICE - copy from host to host e.g., memcpy
* locTo=LOCATION_DEVICE, locFrom=LOCATION_HOST - copy from host to host e.g., memcpy
* locTo=LOCATION_DEVICE, locFrom=LOCATION_DEVICE - copy from host to host e.g., memcpy
* SetExecutionMode
* location=LOCATION_DEVICE - execute on the host
* location=LOCATION_HOST - execute on the host
*
* Using a device, not using managed memory
* Malloc(..., location)
* location=LOCATION_DEVICE - device malloc e.g., cudaMalloc
* location=LOCATION_HOST - host malloc e.g., malloc
* MemoryCopy(..., locTo,locFrom)
* locTo=LOCATION_HOST, locFrom=LOCATION_DEVICE - copy from device to host e.g., cudaMemcpy
* locTo=LOCATION_DEVICE, locFrom=LOCATION_HOST - copy from host to device e.g., cudaMemcpy
* locTo=LOCATION_DEVICE, locFrom=LOCATION_DEVICE - copy from device to device e.g., cudaMemcpy
* SetExecutionMode
* location=LOCATION_DEVICE - execute on the device
* location=LOCATION_HOST - execute on the host
*
* Using a device, using managed memory
* Malloc(..., location)
* location=LOCATION_DEVICE - managed malloc e.g., cudaMallocManaged
* location=LOCATION_HOST - host malloc e.g., malloc
* MemoryCopy(..., locTo,locFrom)
* locTo=LOCATION_HOST, locFrom=LOCATION_DEVICE - copy from device to host e.g., cudaMallocManaged
* locTo=LOCATION_DEVICE, locFrom=LOCATION_HOST - copy from host to device e.g., cudaMallocManaged
* locTo=LOCATION_DEVICE, locFrom=LOCATION_DEVICE - copy from device to device e.g., cudaMallocManaged

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.
??? Also following the old parser, typedef names may be
redeclared in declarators, but not Objective-C class names. */

Although they are erroneous if the labels declared aren't defined,
is it useful for the syntax to be this way?
