Member Function Documentation

◆ Evaluate()

llvm::Expected< lldb::ValueObjectSP > lldb_private::dil::Interpreter::Evaluate ( const ASTNode & node )

Evaluate an ASTNode.

Returns: A non-null lldb::ValueObjectSP or an Error.

Definition at line 268 of file DILEval.cpp.

References lldb_private::dil::ASTNode::Accept(), lldb_private::dil::ASTNode::GetLocation(), and m_expr.

◆ EvaluateAndDereference()

llvm::Expected< lldb::ValueObjectSP > lldb_private::dil::Interpreter::EvaluateAndDereference ( const ASTNode & node )

private

Evaluate an ASTNode.

If the result is a reference, it is also dereferenced using ValueObject::Dereference.

Returns: A non-null lldb::ValueObjectSP or an Error.

Definition at line 281 of file DILEval.cpp.

References error(), and Evaluate().

◆ UnaryConversion()

llvm::Expected< lldb::ValueObjectSP > lldb_private::dil::Interpreter::UnaryConversion	(	lldb::ValueObjectSP	valobj,
		uint32_t	location )

private

Perform usual unary conversions on a value.

At the moment this includes array-to-pointer and integral promotion for eligible types.

Definition at line 83 of file DILEval.cpp.

◆ VerifyArithmeticCast()

llvm::Expected< CastKind > lldb_private::dil::Interpreter::VerifyArithmeticCast	(	CompilerType	source_type,
		CompilerType	target_type,
		int	location )

private

A helper function for VerifyCastType (below).

This performs arithmetic-specific checks. It should only be called if the target_type is a scalar type.
