Add the core architecture for the lld driver. This includes selecting which driver to emulate, option parsing, invocation building, and running the link. This currently only supports a very basic subset of ld for x86_64-linux. lld -flavor ld obj.o -o obj or symlink lld as (ld , link, ld64, core) to get the desired behavior without -flavor. llvm-svn: 169659

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

This adds functionality for undefined atoms from dynamic libraries to be added to the list of undefined atoms. The processing of undefined atoms from dynamic libraries is controlled by use-shlib-undefines command line option. This patch also adds additional command line arguments to allow/disallow unresolved symbols from shared libraries and mimics GNU ld behavior. llvm-svn: 179257
