[pypy-svn] r70501 - in pypy/branch/loop-invariant-decorator/pypy/jit: backend metainterp

[cfbolz at codespeak.net]

Author: cfbolz

New Revision: 70501

Modified:
   pypy/branch/loop-invariant-decorator/pypy/jit/backend/model.py
   pypy/branch/loop-invariant-decorator/pypy/jit/metainterp/resoperation.py
Log:
Add a new operation CALL_LOOPINVARIANT. The operation behaves exactly like CALL.
The idea is that the backend never has to generate code for this operation,
because the optimizer turns it into a normal CALL.
