This represents clause 'in_reduction' in the '#pragma omp task' directives.

#pragma omp task in_reduction(+:a,b)

In this example directive '#pragma omp task' has clause 'in_reduction' with operator '+' and the variables 'a' and 'b'.

Creates clause with a list of variables VL.

Parameters

StartLoc Starting location of the clause.
LParenLoc Location of '('.
ColonLoc Location of ':'.
EndLoc Ending location of the clause.
VL The variables in the clause.
QualifierLoc The nested-name qualifier with location information
NameInfo The full name info for reduction identifier.
Privates List of helper expressions for proper generation of private copies.
LHSExprs List of helper expressions for proper generation of assignment operation required for copyprivate clause. This list represents LHSs of the reduction expressions.
RHSExprs List of helper expressions for proper generation of assignment operation required for copyprivate clause. This list represents RHSs of the reduction expressions. Also, variables in these expressions are used for proper initialization of reduction copies.
ReductionOps List of helper expressions that represents reduction expressions: LHSExprs binop RHSExprs; operator binop(LHSExpr, RHSExpr); (LHSExpr, RHSExpr); Required for proper codegen of final reduction operation performed by the reduction clause.
TaskgroupDescriptors List of helper taskgroup descriptors for corresponding items in parent taskgroup task_reduction clause.
PreInit Statement that must be executed before entering the OpenMP region with this clause.
PostUpdate Expression that must be executed after exit from the OpenMP region with this clause.
