George Rimar 77b7779b48 Reapply r254098. 
Fix is (OutputSections.cpp):
for (std::pair<const SymbolBody *, size_t> &I : Entries) {
 =>
for (std::pair<const SymbolBody *, unsigned> &I : Entries) {

README.md

The New ELF Linker

This directory contains a port of the new PE/COFF linker for ELF.

Overall Design

See COFF/README.md for details on the design. Note that unlike COFF, we do not distinguish chunks from input sections; they are merged together.

Capabilities

This linker can link LLVM and Clang on Linux/x86-64 or FreeBSD/x86-64 with -LLVM_ENABLE_THREADS=OFF. "Hello world" can be linked on Linux/PPC64.

Performance

Achieving good performance is one of our goals. It's too early to reach a conclusion, but we are optimistic about that as it currently seems to be faster than GNU gold. It will be interesting to compare when we are close to feature parity.
