[Vm-dev] Functional callbacks on all Cog platforms

Hi All,

    just wanted to report that as of Alien-eem.35 and
we now have functional callbacks on all x86 platforms, ARM32 platforms and
x86_64 platforms.

There's a simple example Alien class>>exampleCqsort that shows how to use
the system and tests the implementation using the C library's sort quick
sort implementation that takes a function pointer as an argument to use for
comparing pairs of elements.  This is mapped onto a Smalltalk block by
Alien's callback implementation.  The example sorts 100 random
double-precision floats using qsort and a callback into Smalltalk.

best, Eliot
