◆ visitLocationList()

overridevirtual

Call the user-provided callback for each entry (including the end-of-list entry) in the location list starting at Offset.

The callback can return false to terminate the iteration early. Returns an error if it was unable to parse the entire location list correctly. Upon successful termination Offset will be updated point past the end of the list.

Implements llvm::DWARFLocationTable.
