Look for as.info, node: "Symbols Names". It say that you can use up to ten
local labels (0..9) and make reference to the nearest ([f]orward of
[b]ackward) one:
   asm volatile (" ...
         0:    ...			// the local label
                loop 0b		// refer to the most recent definition of 0
                   ... ");
