@defgroup ATOMIC_OPS Atomic Operations
These functions are used for implementing the many different varieties of atomic
operations.

The compiler is at liberty to inline atomic operations that are naturally
supported by the target architecture. For instance on IA-32 architecture an
atomic like this can be inlined
@code
static int s = 0;
#pragma omp atomic
    s++;
@endcode
using the single instruction: `lock; incl s`

However the runtime does provide entrypoints for these operations to support
compilers that choose not to inline them. (For instance,
`__kmpc_atomic_fixed4_add` could be used to perform the increment above.)

The names of the functions are encoded by using the data type name and the
operation name, as in these tables.

Data Type  | Data type encoding
-----------|---------------
int8_t     | `fixed1`
uint8_t    | `fixed1u`
int16_t    | `fixed2`
uint16_t   | `fixed2u`
int32_t    | `fixed4`
uint32_t   | `fixed4u`
int32_t    | `fixed8`
uint32_t   | `fixed8u`
float      | `float4`
double     | `float8`
float 10 (8087 eighty bit float)  | `float10`
complex<float>   |  `cmplx4`
complex<double>  | `cmplx8`
complex<float10> | `cmplx10`
<br>

Operation | Operation encoding
----------|-------------------
+ | add
- | sub
\* | mul
/ | div
& | andb
<< | shl
\>\> | shr
\| | orb
^  | xor
&& | andl
\|\| | orl
maximum | max
minimum | min
.eqv.   | eqv
.neqv.  | neqv

<br>
For non-commutative operations, `_rev` can also be added for the reversed
operation. For the functions that capture the result, the suffix `_cpt` is
added.

Update Functions
================
The general form of an atomic function that just performs an update (without a
`capture`)
@code
void __kmpc_atomic_<datatype>_<operation>( ident_t *id_ref, int gtid, TYPE *
lhs, TYPE rhs );
@endcode
@param ident_t  a pointer to source location
@param gtid  the global thread id
@param lhs   a pointer to the left operand
@param rhs   the right operand

`capture` functions
===================
The capture functions perform an atomic update and return a result, which is
either the value before the capture, or that after. They take an additional
argument to determine which result is returned.
Their general form is therefore
@code
TYPE __kmpc_atomic_<datatype>_<operation>_cpt( ident_t *id_ref, int gtid, TYPE *
lhs, TYPE rhs, int flag );
@endcode
@param ident_t  a pointer to source location
@param gtid  the global thread id
@param lhs   a pointer to the left operand
@param rhs   the right operand
@param flag  one if the result is to be captured *after* the operation, zero if
captured *before*.

The one set of exceptions to this is the `complex<float>` type where the value
is not returned, rather an extra argument pointer is passed.

They look like
@code
void __kmpc_atomic_cmplx4_<op>_cpt(  ident_t *id_ref, int gtid, kmp_cmplx32 *
lhs, kmp_cmplx32 rhs, kmp_cmplx32 * out, int flag );
@endcode

Read and Write Operations
=========================
The OpenMP<sup>*</sup> standard now supports atomic operations that simply
ensure that the value is read or written atomically, with no modification
performed. In many cases on IA-32 architecture these operations can be inlined
since the architecture guarantees that no tearing occurs on aligned objects
accessed with a single memory operation of up to 64 bits in size.

The general form of the read operations is
@code
TYPE __kmpc_atomic_<type>_rd ( ident_t *id_ref, int gtid, TYPE * loc );
@endcode

For the write operations the form is
@code
void __kmpc_atomic_<type>_wr ( ident_t *id_ref, int gtid, TYPE * lhs, TYPE rhs
);
@endcode

Full list of functions
======================
This leads to the generation of 376 atomic functions, as follows.

Functions for Complex types
---------------------------
Functions for complex types whose component floating point variables are of size
4,8,10 or 16 bytes. The names here are based on the size of the component float,
*not* the size of the complex type. So `__kmpc_atomic_cmplx8_add` is an
operation on a `complex<double>` or `complex(kind=8)`, *not* `complex<float>`.

// For GNU compatibility, we may need to use a critical section,
// even though it is not required by the ISA.
//
// On IA-32 architecture, all atomic operations except for fixed 4 byte add,
// sub, and bitwise logical ops, and 1 & 2 byte logical ops use a common
// critical section.  On Intel(R) 64, all atomic operations are done with fetch
// and add or compare and exchange.  Therefore, the FLAG parameter to this
// macro is either KMP_ARCH_X86 or 0 (or 1, for Intel-specific extension which
// require a critical section, where we predict that they will be implemented
// in the Gnu codegen by calling GOMP_atomic_start() / GOMP_atomic_end()).
//
// When the OP_GOMP_CRITICAL macro is used in a *CRITICAL* macro construct,
// the FLAG parameter should always be 1.  If we know that we will be using
// a critical section, then we want to make certain that we use the generic
// lock __kmp_atomic_lock to protect the atomic update, and not of of the
// locks that are specialized based upon the size or type of the data.
//
// If FLAG is 0, then we are relying on dead code elimination by the build
// compiler to get rid of the useless block of code, and save a needless
// branch at runtime.
