[LLVMdev] Should LLVM JIT default to lazy or non-lazy?

A performance argument in favor of lazy JIT:

If you're creating functions that contain calls to large amounts of
seldom-used code, (or takes the address of a ton of functions, only a
few of which end up being used) then lazy JIT is a win regardless of
how carefully you only JIT what you want to call.  I'm not sure how
frequent a use case this is, though.
