[llvm-dev] Vectorization of math function failed?

[Alexandre Bique via llvm-dev]

I've tried to do:

clang++ -O3 -march=native -mtune=native \
-Rpass=loop-vectorize,slp-vectorize
-Rpass-missed=loop-vectorize,slp-vectorize
-Rpass-analysis=loop-vectorize,slp-vectorize \
-ffast-math -ffp-model=fast -ffp-exception-behavior=ignore -ffp-contract=fast \
-c -o vec.o vec.cc

But I've got no feedback.
