LLD has been redesigned. LLD as released in 3.7 can link itself faster than MSVC's LINK.exe at a factor of around 2x. It can correctly link some large projects like Google Chrome and LLVM itself but I'd still call it rather experimental.
Work is ongoing to support features like COMDAT folding.
Thanks for the update. :) I know that the folks in the Rust project are curious about LLD's potential to provide a linker that Just Works on any of the platforms they target.
