Branch: oparser-mock-model
Changeset: r44855:da29984ae88b
Date: 2011-06-09 11:37 +0200
http://bitbucket.org/pypy/pypy/changeset/da29984ae88b/
Log: make it possible to use either the "real model", which uses the real
BoxInt&co. or the "mock model", which uses mock objects; by default
the real one is used, but the jitlogparser (used by the jitviewer)
uses the latter
