Smalltalk and tiered compile data

[Mark Roos]

Christian asked:

        What exactly do you mean by "invalidate call sites before the 
benchmark"? 
        Are you using MutableCallSites and call setTarget on them?

Exactly.  I am using setTarget to set each call site to its initial 
fallback method.  This should drop the
GWT lookup chain forcing each call site to rebuild the chain.  The method 
handles for the code   still exist but
the GWTs that reference them are gone.  This is my current way to force 
the call sites to get new versions
of the method code.

thanks
