New Revision: 64653

Modified:
   pypy/branch/pyjitpl5/pypy/jit/metainterp/compile.py
Log:
don't store pseudo-loops in possible compiled merge points. I must admit I have
a bit no clue what I'm doing, except I'm pretty sure optimize_bridge should
not randomly return pseudo loop. Also don't know how to write a test.
