Yep, I gave LLD 3.9 a try on Win64 some weeks ago. Works out of 
the box as drop-in replacement for Microsoft's link.exe, incl. 
usage of environment variables. What's apparently still lacking 
is debuginfos (.pdb) generation, so our CDB debugging tests 
failed (all others worked IIRC).
LLD is supposed to be significantly faster than Microsoft's 
linker; I haven't done any measurements yet. Besides offering 
nice stuff like LTO, integrating LLD should allow LDC to directly 
cross-compile *and* cross-link. So you'll only need the target 
system libs to produce objects, libraries and executables for 
'any' target. Which is pretty awesome.
