[Qemu-devel] [PATCHv3 3/9] buffer_is_zero: use vector optimizations if possible

performance gain on SSE2 is approx. 20-25%. altivec is not tested. performance for unsigned long arithmetic is unchanged. Signed-off-by: Peter Lieven --- util/cutils.c |5 + 1 file changed, 5 insertions(+) diff --git a/util/cutils.c b/util/cutils.c index 6d079ac..52205a2 100644 --- a/ut
