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.

template<typename DWARFListType >
Expected< DWARFListType > llvm::DWARFListTableBase< DWARFListType >::findList ( DWARFDataExtractor  Data,

Look up a list based on a given offset.

Extract it and enter it into the list map if necessary.

◆ getHeaderSize()

template<typename DWARFListType>
uint8_t llvm::DWARFListTableBase< DWARFListType >::getHeaderSize ( ) const
inline

Return the size of the table header including the length but not including the offsets.

This is dependent on the table format, which is unambiguously derived from parsing the table.

Return the contents of the offset entry designated by a given index.
