llvm dev - Sep 2005 - [LLVMdev] Staged LLVM emulator

Were there ever any plans to make a staged emulator that only JIT's hot
functions (interpreting the lesser used ones)?  Emulators such as this tend
to perform better when there are a lot of infrequently used functions.

I'm not aware of any work to implement this sort of thing, but it 
shouldn't be too hard.  We're currently lacking a decent interpreter, so
that would be the first place to start.

I might be able to work on that in spare time, we'll see.  Do you think
it's
a worthwhile thing to work on?
