[squeak-dev] alien for powerpc

> Ok, I've spent a number of hours(days?) to build some more SUnits  
> and create a working Alien plugin for PowerPC that at least
> lets you get/put byte, short, long, and long long data  (32 bit  
> based), plus call APIs that use that type of data.
>
> At the moment Float/Double does not work because of some decisions  
> about how to handle Float versus Long have not been made yet.
> Therefore you cannot work with Float or Double objects.
>
> Please find a 32bit universal plugin on the ftp site in the  
> experimental folder.
> http://www.smalltalkconsulting.com/squeak.html
> look for the
> IA32ABI.1.0.1.bundle.zip
>
> It would be helpful if some folks could poke at things a bit  to  
> understand how workable things are at the moment.
>
> Tomorrow if time permits I'll look at structures, and I need some  
> more Sunits to handle Alien objects that
> embed the data in the smalltalk object, versus Alien objects that  
> use malloc and then point to the malloced storage area.
> Astute readers will know that Alien uses negative/positive size to  
> mediate the type, and the Sunits don't attempt usage of both types yet
> to ensure there is proper coverage of the plugin support code.
