Detailed Description

A class that transforms the DWARF in a DWARFContext into GSYM information by populating the GsymCreator object that it is constructed with.

This class supports converting all DW_TAG_subprogram DIEs into gsym::FunctionInfo objects that includes line table information and inline function information. Creating a separate class to transform this data allows this class to be unit tested.
