This is my Driver refactoring patch. The major changes are: 1) LinkerOptions has been merged into TargetInfo 2) LinkerInvocation has been merged into Driver 3) Drivers no longer convert arguments into an intermediate (core) argument list, but instead create a TargetInfo object and call setter methods on it. This is only how in-process linking would work. That is, you can programmatically set up a TargetInfo object which controls the linking. 4) Lots of tweaks to test suite to work with driver changes 5) Add the DarwinDriver 6) I heavily doxygen commented TargetInfo.h Things to do after this patch is committed: a) Consider renaming TargetInfo, given its new roll. b) Consider pulling the list of input files out of TargetInfo. This will enable in-process clients to create one TargetInfo the re-use it with different input file lists. c) Work out a way for Drivers to format the warnings and error done in core linking. llvm-svn: 178776

# RUN: lld -core %s --add-pass stubs | FileCheck %s
Sources now require C++11 to build. Add first linker pass (StubsPass) which looks for calls to shared library symbols and replaces them with calls to a StubAtom. On ELF system, a "stub" is a PLT entry. Added a simple test case. Pass a Platform object to YAML reader and writer for converting fixup kinds between names and values. Change output of Resolver to be a File object instead of a vector of Atoms. Thus, passes operate on a File instead of just Atoms. Rework how to walk through a File's Atoms. Now iterator based instead of a method that visits each atom. llvm-svn: 152269

Removes files for separate ReaderYAML.cpp and WriterYAML.cpp and adds a new file ReaderWriterYAML.cpp that uses YAML I/O. Lots of tweaks to test suite for slightly different YAML encoding. llvm-svn: 171592
