Sorry, I made a mistake.  Dmd simply invokes the system C 
compiler and the linker that it uses.  I set CC to clang and 
build dmd trunk with it.  Clang uses gold, which is what led me 
to assume it was the default.  But I just checked and gcc, the 
default C compiler on Arch, uses bfd ld, so it depends on what 
you use as your C compiler.

See above, I was wrong.

As for llvm-based linkers, there are a couple going around.  The 
one you're probably thinking of is lld:
