std::optional< uint64_t > DWARFDebugNames::Entry::getCUIndex | ( | ) | const |
Returns the Index into the Compilation Unit list of the owning Name Index or std::nullopt if this Accelerator Entry does not have an associated Compilation Unit.
It is up to the user to verify that the returned Index is valid in the owning NameIndex (or use getCUOffset(), which will handle that check itself). Note that entries in NameIndexes which index just a single Compilation Unit are implicitly associated with that unit, so this function will return 0 even without an explicit DW_IDX_compile_unit attribute, unless there is a DW_IDX_type_unit attribute.
