◆ GetForeignTypeUnit()

std::optional< DWARFTypeUnit * > DebugNamesDWARFIndex::GetForeignTypeUnit ( const DebugNames::Entry & entry ) const

private

Checks if an entry is a foreign TU and fetch the type unit.

This function checks if the DebugNames::Entry refers to a foreign TU and returns an optional with a value of the entry is a foreign type unit entry. A valid pointer will be returned if this entry is from a .dwo file or if it is from a .dwp file and it matches the type unit's originating .dwo file by verifying that the DW_TAG_type_unit DIE has a DW_AT_dwo_name that matches the DWO name from the originating skeleton compile unit.

Parameters

[in] entry The accelerator table entry to check.

Returns

A std::optional that has a value if this entry represents a foreign type unit. If the pointer is valid, then we were able to find and match the entry to the type unit in the .dwo or .dwp file. The returned value can have a valid, yet contain NULL in the following cases:

we were not able to load the .dwo file (missing or DWO ID mismatch)
we were able to load the .dwp file, but the type units DWO name doesn't match the originating skeleton compile unit's entry Returns std::nullopt if this entry is not a foreign type unit entry.

Returns true if parent_contexts entries are within parent_chain.

This is diffferent from SameParentChain() which checks for exact match. This function is required because parent_chain can contain inline namespace entries which may not be specified in parent_contexts by client.

Parameters

[in]	parent_contexts	The list of parent contexts to check for.
[in]	parent_chain	The fully qualified parent chain entries from .debug_names index table to check against.

Returns: True if all parent_contexts entries are can be sequentially found inside parent_chain, otherwise False.
