[pypy-dev] Performance Regression with SVN version 50525

[Michael Schneider]

Looks like Carls' fix took care of the issue:

(10:23:58 AM) *bigdog:* cfbolts: Translation timings for 50557
(10:24:01 AM) *bigdog:* [Timer] Timings:
(10:24:01 AM) *bigdog:* [Timer] annotate - 329.5 s
(10:24:01 AM) *bigdog:* [Timer] rtype_lltype - 172.7 s
(10:24:01 AM) *bigdog:* [Timer] backendopt_lltype - 182.5 s
(10:24:01 AM) *bigdog:* [Timer] stackcheckinsertion_lltype - 12.3 s
(10:24:01 AM) *bigdog:* [Timer] database_c - 124.8 s
(10:24:01 AM) *bigdog:* [Timer] source_c - 67.7 s
(10:24:01 AM) *bigdog:* [Timer] compile_c - 0.1 s
(10:24:01 AM) *bigdog:* [Timer] ========================================
(10:24:01 AM) *bigdog:* [Timer] Total: - 889.5 s


Very good work, amazing turnaround time.

Thanks,
Mike
