Running a JIT in a Python interpreter
I'm debugging a JIT that's aborting during tracing for some strange reason. I remember several years ago someone here pointed me to a file in the code repo that showed how to run a RPython JIT in interpreted mode, so you can place a breakpoint in the jit hooks. I remember this being a great help last time I had this problem. Does anyone remember where that code is? Thanks! Timothy
Ah! Found it in the rtyper test code. Timothy On Thu, Dec 6, 2018 at 5:07 PM Timothy Baldridge <tbaldridge@gmail.com> wrote:

Hi Timothy, that code is always super messy, but I've also been using it in various smaller interpreters (PyPy is too slow to translate to have it be useful). E.g. here is what Pycket has: https://github.com/pycket/pycket/blob/master/pycket/test/jit.py Cheers, Carl Friedrich On 07/12/2018 01:07, Timothy Baldridge wrote:
