This make it +more efficient when building large strings, e.g. with cStringIO(). + +Also, use systematically jit.conditional_call() instead of regular +branches. This lets the JIT make more linear code, at the cost of +forcing a bit more data (to be passed as arguments to +conditional_calls). I would expect the net result to be a slight +slow-down on some simple benchmarks and a speed-up on bigger +programs. _______________________________________________ pypy-commit mailing list pypy-commit@python.org https://mail.python.org/mailman/listinfo/pypy-commit
