Detailed Description

This subclass of OperationUnary represents a cast operation.

This class is used to represent opcodes whose first argument is a value and the second argument is a type. It is used for opcodes that in some way manipulate the data to conform to the given type. In some cases, the value itself is not modified and is returned exactly as it was with only new type information (reinterpret casts), and in some cases, the value itself changes such as sign extending integers or conversions from integers to floating-point numbers. Each individual opcode carries the rules for these conversions. This class is merely a container for instances of those operations.

Constructor & Destructor Documentation

◆ OperationCast()

OperationCast::OperationCast	(	OperationType	_type,
		const Gyoji::context::SourceReference &	_src_ref,
		size_t	_result,
		size_t	_operand,
		const Type *	_cast_type
	)

Construct cast operation with a single operand and a type.

This constructor is used for cast expressions which take a single operand and a reference to a type and produce a single result.

◆ ~OperationCast()

OperationCast::~OperationCast ( )

virtual

Move along, nothing to see here.

Member Function Documentation

◆ get_cast_type()

const Type * OperationCast::get_cast_type ( ) const

Get type being cast/converted to.

This method returns the type of variable being cast or converted to.

◆ get_description()

std::string OperationCast::get_description ( ) const

protectedvirtual

Produce a description of the operation.

This method returns a full description of the operation including the return-value, operands, and any other ancilary information about the operation. This is a string that is constructed dynamically when needed and is used almost exclusively by the "dump" method to provide debuginng information.

Reimplemented from Gyoji::mir::Operation.
