Re: [PATCH] trivial: the memset operation on a automatic array variable should be optimized out by data initialization

I think all these benefits are the gcc's __builtin_memset optimization
than the explicit call to memset.

... or from complex memset() implementation (some chips even didn't do
`rep' fast enough somehow). Maybe code like below will be acceptable for
both optimizers and maintainers?

we should just alias our memset to the __builtin one, and then provide a
generic one from lib/ for the cases gcc needs to do a fallback.
