Rose::BinaryAnalysis::ConcreteLocation Class Reference

Description

Concrete location of data.

A concrete location is a machine register, a concrete memory address, or a memory address calculated from a register's current value and a signed byte offset.

Concrete locations are immutable objects.

Constructor & Destructor Documentation

ConcreteLocation() [1/6]

Rose::BinaryAnalysis::ConcreteLocation::ConcreteLocation

(

)

Default constructor.

Constructs a concrete location that does not refer to any location. The isEmpty method return true for such objects.

ConcreteLocation() [2/6]

Rose::BinaryAnalysis::ConcreteLocation::ConcreteLocation ( RegisterDescriptor  )

explicit

Register location.

Construct a concrete location that refers to a register. The optional register dictionary can be associated with the location and is only used when printing the location.

ConcreteLocation() [3/6]

Rose::BinaryAnalysis::ConcreteLocation::ConcreteLocation ( RegisterDescriptor  , const RegisterDictionaryPtr &    )

explicit

Register location.

Construct a concrete location that refers to a register. The optional register dictionary can be associated with the location and is only used when printing the location.

ConcreteLocation() [4/6]

Rose::BinaryAnalysis::ConcreteLocation::ConcreteLocation ( Address  )

explicit

Address location.

Construct a concrete location that refers to an address in memory.

ConcreteLocation() [5/6]

Rose::BinaryAnalysis::ConcreteLocation::ConcreteLocation	(	RegisterDescriptor	,
		int64_t	offset
	)

Register and offset location.

Construct a concrete location that refers to an address in memory calculated by adding a register's value and a signed byte offset. The optional register dictionary can be associated with the location and is only used when printing the location.

ConcreteLocation() [6/6]

Rose::BinaryAnalysis::ConcreteLocation::ConcreteLocation	(	RegisterDescriptor	,
		int64_t	offset,
		const RegisterDictionaryPtr &
	)

Register and offset location.

Construct a concrete location that refers to an address in memory calculated by adding a register's value and a signed byte offset. The optional register dictionary can be associated with the location and is only used when printing the location.

Member Function Documentation

isValid()

virtual bool Rose::BinaryAnalysis::ConcreteLocation::isValid ( ) const

overridevirtual

Test whether this object is valid.

Implements Rose::Location.

toString()

virtual std::string Rose::BinaryAnalysis::ConcreteLocation::toString ( ) const

overridevirtual

Convert location to string.

Returns a string representation of the location. This representation is not necessarily parsable.

See also, print.

Implements Rose::Location.

print() [1/2]

virtual void Rose::BinaryAnalysis::ConcreteLocation::print ( std::ostream &  ) const

overridevirtual

Output location to a stream.

The format is the same as the toString method and is not necessarily parsable.

See also, toString.

Implements Rose::Location.

printableName()

virtual std::string Rose::BinaryAnalysis::ConcreteLocation::printableName ( ) const

overridevirtual

Convert location to escaped, parsable string.

Returns a string that can be safely emitted to a terminal. The format should also be parsable so the static parse method in subclasses can create an equal object from the string.

Implements Rose::Location.

isEqual()

virtual bool Rose::BinaryAnalysis::ConcreteLocation::isEqual ( const Location &  other ) const

overridevirtual

Equality and inequality.

Objects are equal if they are the same type and they point to the same location. Otherwise they are unequal.

The operator== is implemented in the base class only. For the expression a == b it calls both a.isEqual(b) and b.isEqual(a), returning true only if both tests return true. Subclasses should implement x.isEqual(y) by dynamic casting y to the type of x and returning true if and only if the cast succeeds and x and y point to the same location.

The operator!= is implemented in the base class as the complement of operator==.

Implements Rose::Location.

operator<()

virtual bool Rose::BinaryAnalysis::ConcreteLocation::operator< ( const Location &  ) const

overridevirtual

Implements Rose::Location.

operator<=()

virtual bool Rose::BinaryAnalysis::ConcreteLocation::operator<= ( const Location &  ) const

overridevirtual

Implements Rose::Location.

operator>()

virtual bool Rose::BinaryAnalysis::ConcreteLocation::operator> ( const Location &  ) const

overridevirtual

Implements Rose::Location.

operator>=()

virtual bool Rose::BinaryAnalysis::ConcreteLocation::operator>= ( const Location &  ) const

overridevirtual

Implements Rose::Location.

print() [2/2]

void Rose::BinaryAnalysis::ConcreteLocation::print	(	std::ostream &	,
		const RegisterDictionaryPtr &
	)		const

Print using the specified register dictionary.

Concrete locations have an optional internal register dictionary pointer that's usually used for printing, but this method provides a way to use some other register dictionary.

compare()

int Rose::BinaryAnalysis::ConcreteLocation::compare

(

const ConcreteLocation &

)

const

Compare two concrete locations.

Returns negative if this location is less than the other, positive if this location is greater than the other, or zero if this and the other location are equal.

registerDictionary() [1/2]

RegisterDictionaryPtr Rose::BinaryAnalysis::ConcreteLocation::registerDictionary

(

)

const

Property: Register dictionary.

This is the optional register dictionary associated with this location and used when printing the location.

registerDictionary() [2/2]

void Rose::BinaryAnalysis::ConcreteLocation::registerDictionary

(

const RegisterDictionaryPtr &

)

Property: Register dictionary.

This is the optional register dictionary associated with this location and used when printing the location.

reg()

RegisterDescriptor Rose::BinaryAnalysis::ConcreteLocation::reg

(

)

const

Register part of the location.

Returns the register part of the location. This returns a valid register descriptor if the location is either a register or an indirect (register plus offset) memory address. Otherwise it returns the empty register descriptor.

address()

Address Rose::BinaryAnalysis::ConcreteLocation::address

(

)

const

Address part of the location.

Returns the address of the location if the location is a simple memory address. Otherwise, if the address is formed from a base register and an offset, or if the location is a register, then zero is returned.

offset()

int64_t Rose::BinaryAnalysis::ConcreteLocation::offset

(

)

const

Offset part of the location.

Returns the signed offset when the location is a memory address formed from a register base value and an offset. Otherwise it returns zero.
