[Python-Dev] A new JIT compiler for a faster CPython? (original) (raw)

It's the JIT compiler of Unladen Swallow that "failed"; in my understanding because LLVM is crap (i.e. it is slow, memory-consuming, and buggy) - as a low-level virtual machine; it may be ok as a compiler backend (but I still think it is buggy there as well).

What is the status of LLVM nowadays? Is it not a good solution to write a portable JIT?

I don't want to write my own library to generate machine code.

psyco is no more maintained. I think this is factually incorrect: Christian Tismer maintains it (IIUC).

http://psyco.sourceforge.net/ says:

"News, 12 March 2012

Psyco is unmaintained and dead. Please look at PyPy for the state-of-the-art in JIT compilers for Python."
