Detailed Description
These functions are used for implementing #pragma omp for, #pragma omp sections, #pragma omp single and #pragma omp master constructs.
When handling loops, there are different functions for each of the signed and unsigned 32 and 64 bit integer types which have the name suffixes _4, _4u, _8 and _8u. The semantics of each of the functions is the same, so they are only described once.
Static loop scheduling is handled by __kmpc_for_static_init_4 and friends. Only a single call is needed, since the iterations to be executed by any give thread can be determined as soon as the loop parameters are known.
Dynamic scheduling is handled by the __kmpc_dispatch_init_4 and __kmpc_dispatch_next_4 functions. The init function is called once in each thread outside the loop, while the next function is called each time that the previous chunk of work has been exhausted.
Enumeration Type Documentation
◆ sched_type

Each of the four functions here are identical apart from the argument types.

◆ __kmpc_sections_init()
- Parameters
-

Beginning of sections construct. There are no implicit barriers in the "sections" calls, rather the compiler should introduce an explicit barrier if it is required.
This implementation is based on __kmp_dispatch_init, using same constructs for shared data (we can't have sections nested directly in omp for loop, there should be a parallel region in between)

◆ __kmpc_single()
- Parameters
-
loc source location information global_tid global thread number
- Returns
- One if this thread should execute the single construct, zero otherwise.
Test whether to execute a single construct. There are no implicit barriers in the two "single" calls, rather the compiler should introduce an explicit barrier if it is required.

The functions compute the upper and lower bounds and stride to be used for the set of iterations to be executed by the current team from the statically scheduled loop that is described by the initial values of the bounds, stride, increment and chunk for the distribute construct as part of composite distribute parallel loop construct. These functions are all identical apart from the types of the arguments.
