[pypy-issue] [issue1067] Performance on Stack-Based VM machine

[Armin Rigo]

Armin Rigo <armin.rigo at gmail.com> added the comment:

Finally found a simple idea (c7c74257157c): when we hit the limit
'max_unroll_loops', then instead of aborting, retry to compile by
disabling the 'unroll' optimization.

This alone fixes go2.py, which runs 235 times faster now than before,
and 8.7 times faster than CPython.
