PyPy bootstrap for Arch Linux riscv64

README.md

• Since Arch Linux removed Python 2 from its official repository, we need to use AUR scripts. Build python2 from AUR. Note that there's one failed test (test_gdbm), but it should be fine with --nocheck.

• Build python2-cffi, python2-setuptools, python2-pycparser, python2-ply from AUR.

• Use pypy-bootstrap-riscv64.patch below to build first version of pypy on riscv64 with something like:

  $ pwd
  .../archriscv/pypy/repos/community-x86_64
  $ extra-riscv64-build -- -d "/tmp/pkgcache:/var/cache/pacman/pkg/" \
    -I ../../../python2/python2-2.7.18-8-riscv64.pkg.tar.zst \
    -I ../../../python2-cffi/python2-cffi-1.15.0-3-riscv64.pkg.tar.zst \
    -I ../../../python2-pycparser/python2-pycparser-2.21-1-any.pkg.tar.zst \
    -I ../../../python2-ply/python2-ply-3.11-1-any.pkg.tar.zst \
    -I ../../../python2-setuptools/python2-setuptools-2:44.1.1-2-any.pkg.tar.zst
  

• From now on, PyPy can now build itself. Use pypy-riscv64.patch below for future versions.

Newly added build flags are taken from Debian's pypy3 translating script. Without those, PyPy refuses to build.

I've also tried building pypy3 from pypy. It builds fine with original Arch tweaks disabled (see pypy3-riscv64.patch below). I wonder if it is building with its vendored dependencies? (I didn't find that matching string in pypy/goal/targetpypystandalone.py)
