◆ castValueToType()

llvm::Value * castValueToType	(	CodeGenFunction &	CGF,

◆ getDistributeLastprivateVars()

void getDistributeLastprivateVars	(	ASTContext &	Ctx,
		const OMPExecutableDirective &	D,
		llvm::SmallVectorImpl< const ValueDecl * > &	Vars )

◆ getReductionAtomicRMWOp()

std::optional< llvm::AtomicRMWInst::BinOp > getReductionAtomicRMWOp	(	BinaryOperatorKind	BOK,
		QualType	Ty )

static

Maps a built-in reduction operator to an atomicrmw opcode for the atomic cross-team reduction fast path, or nullopt if there is no direct atomicrmw (e.g.

user-defined, complex, fp min/max) so the buffer path is used instead.

◆ getReductionBinOpKind()

std::optional< BinaryOperatorKind > getReductionBinOpKind ( const Expr * ReductionOp )

static

Extracts the built-in reduction operator from a combiner of the form x = x / <op> rhs (or the min/max conditional), or nullopt if the shape is not recognized (e.g.

user-defined reductions).
