id like to see some benchmark done with the latest gcc release
and h264/h263/aac decoding as well as mpeg4 encoding on x86_64 (codecs
randomly picked based more on what is used alot than what uses alot of funny
if nothing gets slower then iam not against this otherwise i think
more investigation is needed

Also how does this stuff interact with restrict ?
Which overrides the other? can we still use restrict to make sure the
gcc is aware that aliasing does not happen?

right to say it. -- Voltaire
