State of the art C compiler optimization tricks

I found this via Lambda the Ultimate: State of the art C compiler optimization tricks. It's a good read, though I would really like to see the presentation rather than just reading the slides. Also, is this really 'state of the art'? Sure, some of the optimizations the compiler does is pretty impressive, but some are... well... not. Is common subexpression elimination really state of the art? Seems like 1970-ish to me...
