Member Function Documentation

isValidOffset()

bool Sci::LocalVariables::isValidOffset ( uint32  offset ) const

inlineoverridevirtual

Check whether the given offset into this memory object is valid, i.e., suitable for passing to dereference.

Implements Sci::SegmentObj.

dereference()

SegmentRef Sci::LocalVariables::dereference ( reg_t  pointer )

overridevirtual

Dereferences a raw memory pointer.

Parameters

reg	reference to dereference

Returns

the data block referenced

Reimplemented from Sci::SegmentObj.

findCanonicAddress()

reg_t Sci::LocalVariables::findCanonicAddress ( SegManager *  segMan, reg_t  sub_addr  ) const

overridevirtual

Finds the canonic address associated with sub_reg. Used by the garbage collector.

For each valid address a, there exists a canonic address c(a) such that c(a) = c(c(a)). This address "governs" a in the sense that deallocating c(a) will deallocate a.

Parameters

sub_addr

base address whose canonic address is to be found

Reimplemented from Sci::SegmentObj.

listAllOutgoingReferences()

Common::Array<reg_t> Sci::LocalVariables::listAllOutgoingReferences ( reg_t  object ) const

overridevirtual

Iterates over all references reachable from the specified object. Used by the garbage collector.

Parameters

object

object (within the current segment) to analyze

Returns

a list of outgoing references within the object

Note

This function may also choose to report numbers (segment 0) as adresses

Reimplemented from Sci::SegmentObj.
