Yes, it is.

Apparently, even without the pass, I still get the same error.

With this command: clang -O3 -emit-llvm testHello.c -c -o new_hello.bc

Here is the problem, thanks for asking this. Even though I installed
clang 3.8.1 with LLVM and I put the /llvm/bin path in my $PATH env
var, my system was using a different version of clang (installed in
/usr/local/bin).
Apparently, the llvm/bin patch doesn't get added to the $PATH
(https://github.com/Homebrew/legacy-homebrew/issues/29733).
Thanks for the support (thanks to Asit as well).
