This probably becomes too complicated, but I thought it was
interesting that the Java people are making use of 32bit pointers on a
64bit system, and are seeing a good performance benefit from it.
afaik, C compilers support this model too, so it shouldn't too hard to
compile GHC in such mode. it's a bit like small/large memory models of
those 16-bit x86 systems :)
Except that you'd need to compile all your libraries in that mode too.
The reason Java can do this is I imagine because they JIT all the code
at runtime so they can change some aspects of code-generation strategy
without recompiling everything.
Cheers,
Simon
