◆ extractFast()

bool DWARFDebugInfoEntry::extractFast ( const DWARFUnit U,
uint64_t OffsetPtr,
const DWARFDataExtractor DebugInfoData,
uint64_t  UEndOffset,
uint32_t  ParentIdx 

Extracts a debug info entry, which is a child of a given unit, starting at a given offset.

If DIE can't be extracted, returns false and doesn't change OffsetPtr. High performance extraction should use this call.
