I just built r117553 from http://llvm.org/svn/llvm-project/llvm/trunk, and 
I'm seeing the same behavior as with 2.7 and 2.8.

% strace -f /home/jdenny/installs/llvm/trunk/bin/llvmc tmp.ll |& grep exec | grep llc
[pid  7015] execve("/home/jdenny/installs/llvm/2.8/bin/llc", ["llc", "-O2", "tmp.ll", "-o", "/tmp/llvm_vbIyN9/tmp.s"], [/* 42 vars */] <unfinished ...>
