[pypy-dev] Any publications regarding PyPy / trace-based JIT compiler?

[Michael Sioutis]

So, after discussing with a Professor of our Department with a very good
knowledge on
the issue, he basically was in the line of "...JIT design decisions that a
tracing JIT encourages versus
the default design of a method JIT...", but to be more specific on the
advantages he claimed that:
"tracing JITs can discover optimization opportunities in common dynamic
execution paths that are not apparent to a static compiler or a
method-based JIT compiler".

I think this is a nice comment overall, that the PyPy publications and the
features they describe can
back up nicely.

Thank you :)
Mike
