static

Creates clause with a list of variables VL.

Parameters
StartLocStarting location of the clause.
LParenLocLocation of '('.
ColonLocLocation of ':'.
EndLocEnding location of the clause.
VLThe variables in the clause.
QualifierLocThe nested-name qualifier with location information
NameInfoThe full name info for reduction identifier.
PrivatesList of helper expressions for proper generation of private copies.
LHSExprsList of helper expressions for proper generation of assignment operation required for copyprivate clause. This list represents LHSs of the reduction expressions.
RHSExprsList 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.
ReductionOpsList of helper expressions that represents reduction expressions:
LHSExprs binop RHSExprs;
operator binop(LHSExpr, RHSExpr);
<CutomReduction>(LHSExpr, RHSExpr);
Required for proper codegen of final reduction operation performed by the reduction clause.
PreInitStatement that must be executed before entering the OpenMP region with this clause.
PostUpdateExpression that must be executed after exit from the OpenMP region with this clause.
