I am currently working on the auto-vectorization phase in the GCC. I
have some points to discuss.
1-- How you define the profitability of auto-vectorization phase? Is
it just the speed up? If we do not get any speed up over scalar code
then there is no need to do auto-parallelization.
2--What are the phases or features in a compiler ( especially in the
GCC) that control the quality of auto-vectorization?
