I've stuck a Squeak 3.8.20beta1U.app.zip file in my EXPERIMENTAL folder found via http://www.smalltalkconsulting.com/squeak.html This test VM contains the latest 32/64 bit integer fetch/set logic & fixes, Alien support and the Alien (IA32ABI) plugin, along with misc fixes to the VM consolidated by Tim and integrated into VMMaker by David T. Lewis in the last few months. If you want to explore Alien then you need this VM and it's plugin to continue. Hint if someone would like to run some benchmarks and compare Alien versus FFI calls that would be good. I note the Alien plugin is macintel only, no powerpc at this time (got funding?) -- = = = ======================================================================== John M.
