Hi, I continued looking into EEMBC benchmarks: - telecom fft is not vectorized because unknown number of iterations. It has both non-constant step and its loop bound may overflow. I think, the solution here could be loop versioning, but since versioning increases code size, this kind of optimization can be less beneficial. - telecom viterbi (vectorization potential gain is 4x) requires conditional store sinking and load hoisting to enable if-conversion. I worked on implementation of store sinking this week.
