Detailed Description

Represents the '#pragma omp split' loop transformation directive.

#pragma omp split counts(3, omp_fill, 2)
for (int i = 0; i < n; ++i)
  ...

This directive transforms a single loop into multiple loops based on index ranges. The transformation splits the iteration space of the loop into multiple contiguous ranges. The counts clause is required and exactly one list item must be omp_fill.

static

Create a new AST node representation for '#pragma omp split'.

Parameters

C	Context of the AST.
StartLoc	Location of the introducer (e.g. the 'omp' token).
EndLoc	Location of the directive's end (e.g. the tok::eod).
Clauses	The directive's clauses (e.g. the required `counts` clause).
NumLoops	Number of affected loops (should be 1 for split).
AssociatedStmt	The outermost associated loop.
TransformedStmt	The loop nest after splitting, or nullptr in dependent contexts.
PreInits	Helper preinits statements for the loop nest.
