Detailed Description

template<typename DWARFListType>
class llvm::DWARFListTableBase< DWARFListType >

A class representing a table of lists as specified in the DWARF v5 standard for location lists and range lists.

The table consists of a header followed by an array of offsets into a DWARF section, followed by zero or more list entries. The list entries are kept in a map where the keys are the lists' section offsets.
