info gcc, node "Extended Asm". The trick I showed you isn't documented
though. It's a pity a more obvious scheme isn't available to say "put
these inputs into different registers", without forcing each one to a
specific register.
One rather good tutorial was written by Colin Plumb <colin@nyx.net>, for
the x86. You can find it at
