◆ buildVariableName()

string ScopeLocal::buildVariableName ( const Address addr,
const Address pc,
Datatype ct,
int4 &  index,
uint4  flags 
) const
virtual

Given an address and data-type, build a suitable generic symbol name.

Parameters
addris the given address
pcis the address at which the name is getting used
ctis a data-type used to inform the name
indexis a reference to an index used to make the name unique, which will be updated
flagsare boolean properties of the variable we need the name for
Returns
the new variable name
