Hi Nick, Here is my understanding, 1) lld-core creates a ReaderOptionsArchive class with the (Reader, CommandLine options flag) 2) lld-core creates an object of type ReaderArchive(ReaderOptions), that users would subclass (off ArchiveLibraryFile) a) GNUArchiveLibrary b) BSDArchiveLibrary b) MachOArchiveLibrary c) COFFArchiveLibrary 3) ReaderArchive has two functions a) parseFile that returns a vector of file objects, if the force load option is set b) parseFile (overloaded) that returns the ArchiveLibra...

...erArchive ::parseFile() method will check the force-load option, if true it will parse up all the members and return an vector<> of File* objects, one for each member. If force-load is not specified, ReaderArchive ::parseFile() will just return one FileArchive object which is a subclass of ArchiveLibraryFile. The find() method of that class will search the table of contents and return a File* object for the member defining the requested symbol, or nullptr if nothing in the archive defines that symbol. > > I think the first set of features that lld needs to support is > > 1) Read t...

Hi, I have started to work on support for Reading archive libraries in lld and thought of using the llvm/lib/ArchiveReader for this. The ArchiveReader doesnot fully support GNU archive libraries (thin archives), do you think we should continue using llvm/lib/ArchiveReader ? I was chatting with Michael and looks like there have been discussions and small sketches done on reading archive
