llvm dev - Dec 2016 - Mail from yangzhh@mail.ustc.edu.cn.

I want to control the unroll factor using the command line flag
“-force-vector-unroll”, such as "clang  -mllvm
-force-vector-unroll=2", but produce an error: " clang-4.0: error:
unknown argument: '-force-vector-unroll=2' " . could you help me ？

The option got renamed to -force-vector-interleave.  That said, we 
shouldn't be advertising -mllvm options in the first place... I'll look 
into updating http://llvm.org/docs/Vectorizers.html .
