Constructor & Destructor Documentation

Immediate() [1/2]

TTAProgram::Immediate::Immediate	(	TerminalImmediate *	value,
		Terminal *	dst
	)

The constructor.

Creates a long immediate with the given value. The value specifies, implicitly, also the width of the instruction field(s) where the immediate bits are encoded). The destination register and the set of instruction slots where the immediate bits are encoded are also given as parameters.

The ownership of the destination terminal object will be passed to the immediate.

Parameters

value	Value of the immediate.
dst	Destination register.

Definition at line 68 of file Immediate.cc.

    : value_(value), dst_(dst), parent_(nullptr) {}

~Immediate()

TTAProgram::Immediate::~Immediate ( )

virtual

The destructor.

Definition at line 74 of file Immediate.cc.

Immediate() [2/2]

TTAProgram::Immediate::Immediate ( const Immediate &  )

private

Copying not allowed.

Member Function Documentation

copy()

std::shared_ptr< Immediate > TTAProgram::Immediate::copy

(

)

const

Makes a copy of the immediate.

The copy is identical, except that it is not registered to the instruction of the original immediate (and therefore, any address it refers to is not meaningful).

Returns

A copy of the immediate.

Definition at line 131 of file Immediate.cc.

                      {
    return std::make_shared<Immediate>(
        dynamic_cast<TerminalImmediate*>(value_->copy()), dst_->copy());
}
