I put it up at 

  http://www.gnat.com/~kenner/gcctut.ppt

It's 173 slides, but was last modified in 2000 and wasn't current then.
It predates tree-ssa and many of the changes in the way that target macros
were handled.

But it does talk about:

    RTL
    RTL optimizers (though the older versions of some)
    Tree nodes and fields
    How to write a front end (though before function-at-a-time)
    How to port to a new machine
