ah, you modified the original commit of mine. Yeah, that works too.
However, I'd add the following to the commit log to account for the
output to input operand move:

Also make 'out' an input-only operand as it is only used as such. This
not only allows gcc to optimize its usage further, but also works around
older gcc versions, apparently failing to handle multiple alternatives
correctly, as in failing to initialize the 'out' operand with its input
