   Oct 23, 2012 · To answer the question you meant to ask: CPython, 3.x or otherwise, does not, never did, and likely never will, contain a JIT compiler. Some other Python implementations (PyPy natively, Jython and IronPython by re-using JIT compilers for the virtual machines they build on) do have a JIT compiler.

   Jan 9, 2024 · A full JIT compiler would normally compile high-level bytecodes like LOAD_FAST into lower level instructions in an IL (Intermediate Language). Because every CPU architecture has different instructions and features, it would be monumentally-complicated to write a compiler that converts high-level code directly to machine code and supports 32-bit and 64-bit CPUs, as well as Apple’s ARM ...

   Does Python 313 have a JIT compiler?

   • Python 3.13 brings two experimental features that open the gateway to much better performance in future releases. These groundbreaking changes will require thorough testing, which is why they’re not currently enabled by default. However, you can try out free threading and the JIT compiler today by building Python from source code.

   Does CPython have a JIT compiler?

   • When CPython is configured and built using the --enable-experimental-jit option, a just-in-time (JIT) compiler is added which may speed up some Python programs. On Windows, use PCbuild/build.bat --experimental-jit to enable the JIT or --experimental-jit-interpreter to enable the Tier 2 interpreter.

   How to build Python 313 without free threading & JIT support?

   • So, you’re going to build the vanilla flavor of Python 3.13 without free threading or JIT support. Ensure that your current working directory is where you compiled Python 3.13 before, and remove any generated build files with make clean. Then, configure the build without the experimental features and compile Python again.

   What is a JIT compiler?

   • What people tend to mean when they say a JIT compiler, is a compiler that emits machine code. This is in contrast to an AOT (Ahead of Time) compiler, like the GNU C compiler, GCC or the Rust compiler rustc which generates the machine code once and distributes as a binary executable. When you run Python code, it is first compiled into bytecodes.
