---------------------
The linker will usually only instantiate your Reader once. That one Reader will
-have its parseFile() method called many times with different input files.
+have its loadFile() method called many times with different input files.
To support multithreaded linking, the Reader may be parsing multiple input
files in parallel. Therefore, there should be no parsing state in you Reader
object. Any parsing state should be in ivars of your File subclass or in
The key method to implement in a reader is::
- virtual error_code parseFile(LinkerInput &input,
- std::vector<std::unique_ptr<File>> &result);
+ virtual error_code loadFile(LinkerInput &input,
+ std::vector<std::unique_ptr<File>> &result);
It takes a memory buffer (which contains the contents of the object file
being read) and returns an instantiated lld::File object which is
virtual const File *find(StringRef name, bool dataSymbolOnly) const = 0;
virtual std::error_code
- parseAllMembers(std::vector<std::unique_ptr<File>> &result) const = 0;
+ parseAllMembers(std::vector<std::unique_ptr<File>> &result) = 0;
/// Returns a set of all defined symbols in the archive, i.e. all
/// resolvable symbol using this file.
/// can do unit testing a driver using non-existing file paths.
class ErrorFile : public File {
public:
- ErrorFile(StringRef p, std::error_code ec) : File(p, kindObject), _ec(ec) {}
+ ErrorFile(StringRef path, std::error_code ec)
