I really doubt that the gcc devs put a lot of effort into something that has no effect. Perhaps not for Pd, that may be true. But they are talking about vectorizing loops, it may not be the best thing to vectorize, but there are definitely vectorizable loops in Pd.
perhaps it would be a good start to reimplement newbytes(n) using memalign(16,n) instead of malloc(n).
A few years ago i introduced aligned memory allocation in the pd- devel branch.
Have you tried submitting a patch? It would be at least useful in Pd- extended. How big a difference did it make?
what makes you think, that just aligning memory regions introduces a performance boost? how can a compiler generate code for aligned memory, if the memory is aligned, but the compiler isn't aware of that?
