[PATCH] [BUG] "Rotate Loop" pass kills "llvm.vectorizer.enable" metadata

[Tyler Nowicki]

Hi Zinovy,

I have a question about your test case. Did you manually add the “llvm.vectorizer.enable” metadata to the IR in Test #1? Or does clang automatically generate the when #pragma omp simd is specified?

Thanks,

Tyler
