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
