> I don't. But the author of Magma used primitives to do this for speed
Actually, Magma doesn't add any primitives whatsoever to Squeak. It is 100%
Profiling various operations in Magma reveals that a lot of time is spent in
the two methods for getting/putting numbers into its ByteArray buffers:
Magma makes hundreds of thousands of calls to these two methods for
serialization, materialization, managing buffers, etc. I tried to make them as
fast as possible by checking for <=32 bits in the first argument and using the
existing primitive under those conditions. But for 64-bit numbers, the most
common, since Magma uses 64-bit oids, it relies on my Smalltalk implementation.
While they do run very fast, if these methods were made primitive, I'm sure
Magma would enjoy a nice turbo-boost.
