Hello,

Yeah, of course. I already did. Refere to the page listed below for
details. I did not look into the results yet, though.

Well, you can implement threaded code on any machine that support
indirect branch instructions. Fortunately, GCC supports the
"label-as-values" feature, which makes it available on any machine
that supports GCC. My optimizations themselves are portable, and I
tested them on a PowerPC for my thesis, too. (AFAIR, llvm supports
this feature, too.)


> Do you have a public repository for the code, so we can take a look?

I have created a patch (as Benjamin wanted) and put all of the
resources (i.e., benchmark results and the patch itself) on my home
page:
