[pypy-dev] unroll if

hi Alex, hi all, I don't have much time for things, about to leave on vacation. Just so that it doesn't get lost: on the unrolling-if branch, if you use the decorator, the JIT should *not* look inside the function if the condition if false. even if the function doesn't contain a loop. so maybe the decorators should be renamed to unroll_iff (too mathematical?) or unroll_exactly_if. Cheers, Carl Friedrich
