It is interesting but also available for other cpus, of course. It explains inner details of the architecture which can be useful if you are a maintainer of gcc ;) This is typical CPU-specific code addressing. How many cycles does a multiply cost and such things. Sadly this is used very rare but highly gifted coders can make use of this information by debugging/profiling and squeeze out the last bit of performance out of a cpu.
Still interesting, of course ;)
