Detailed Description

A Symbol that labels code internal to a function.

Constructor & Destructor Documentation

◆ LabSymbol() [1/2]

LabSymbol::LabSymbol ( Scope sc,
const string &  nm 

Construct given name.

scis the Scope that will contain the new Symbol
nmis the name of the new Symbol

References buildType(), and Symbol::name.

◆ LabSymbol() [2/2]

LabSymbol::LabSymbol ( Scope sc)

Constructor for use with restoreXml.

scis the Scope that will contain the new Symbol

References buildType().

Member Function Documentation

◆ buildType()

void LabSymbol::buildType ( void  )

Build placeholder data-type.

Label symbols don't really have a data-type, so we just put a size 1 placeholder.

References Scope::getArch(), TypeFactory::getBase(), Symbol::scope, Symbol::type, TYPE_UNKNOWN, and Architecture::types.

◆ restoreXml()

void LabSymbol::restoreXml ( const Element el)

Restore this Symbol from an XML stream.

elis the root XML tag of the symbol

Reimplemented from Symbol.

References Symbol::restoreXmlHeader().

◆ saveXml()

void LabSymbol::saveXml ( ostream &  s) const

Save this Symbol to an XML stream.

sis the output stream

Reimplemented from Symbol.
