Detailed Description

The GPRGuardEncoding class maps a guard expression with general purpose register term to a control code.

Instances of this class are always registered to a guard field.

Constructor & Destructor Documentation

◆ GPRGuardEncoding() [1/2]

GPRGuardEncoding::GPRGuardEncoding	(	const std::string &	regFile,
		int	index,
		bool	inverted,
		unsigned int	encoding,
		GuardField &	parent
	)

The constructor.

Creates a guard encoding and Registers it into the given guard field automatically. The guard expression is identified by the name of register file, the index of the GPR and the "invert" flag, all given as parameters.

Parameters

regFile	Name of the register file.
index	The index the GPR.
inverted	The "invert" flag.
encoding	The control code of the guard expression.
parent	The parent guard field.

Exceptions

ObjectAlreadyExists If the guard expression is already encoded in the parent field, or if the given control code is already assigned to another guard expression.

Definition at line 63 of file GPRGuardEncoding.cc.

     : GuardEncoding(inverted, encoding), regFile_(regFile), index_(index) {
     parent.addGuardEncoding(*this);
     setParent(&parent);
 }

◆ GPRGuardEncoding() [2/2]

GPRGuardEncoding::GPRGuardEncoding	(	const ObjectState *	state,
		GuardField &	parent
	)

The constructor.

Loads the state of the object from the given ObjectState instance.

Parameters

state	The ObjectState instance.
parent	The parent guard field.

Exceptions

ObjectStateLoadingException	If an error occurs while loading the state.
ObjectAlreadyExists	If the guard expression is already encoded in the parent field, or if the given control code is already assigned to another guard expression.
