Contribute a RISC-V 64 JIT backend

Hi all, I would like to contribute a RISC-V 64 JIT backend for RPython. I have made some progress at the end of 2023. ## Status My prototype can pass the test cases below: * test_runner.py * test_basic.py and almost all test_ajit.py related tests (except test_rvmprof.py) * test_zrpy_gc_boehm.py I am still working on test_zrpy_gc.py though (p.s. I can pass this if I disable malloc inlining). I haven't done a full translation yet. ## Logistic I wonder how you would like to review the patches? I have roughly 73 pending commits. Each commit has a specific reason for change and corresponding test cases (if applicable). Is it better to just send one GitHub Pull Request containing all of them? Or, do you prefer one commit per Pull Request? Thank you. Regards, Logan

---------- Forwarded message --------- From: Emre Yıldırım <emreyildirim412(a)gmail.com> Date: 26 Feb 2024 Mon at 14:27 Subject: To: <pypy-dev-owner(a)python.org> Hello, I am currently a 3rd year computer science student, studying at University of Manchester and my main project is to measure the difference between pypy and python. Currently, I ran some tests on pypy 3.9 and pypy 3.10. I am seeing that when I ran the experiment with multi-threading, I saw that pypy 3.10 is using more time with processing cpu and using more time in cpu operations. However, in pypy 3.9 when I run the experiments it is using less time on cpu in multi threading mode. I will also talk about that in my report and I want to ask if there is any specific reason for this because isn't pypy 3.10 should also be faster in processing cpu's. Kind regards, Emre
