python-flint0.9.0Cython bindings over the FLINT C library (arbitrary-precision number theory), which itself needs GMP+MPFR. Upstream's own
cibuildwheelrecipe already builds GMP+MPFR+FLINT from source per architecture viabin/cibw_before_all_linux_$(uname -m).sh; this PR adds the riscv64 variant of that script.Differs from upstream
bin/cibw_before_all_linux_riscv64.sh(new file, mirrors the existing x86_64/aarch64 scripts).Why it's feasible: GMP 6.3.0 has a native riscv64 assembly path; FLINT 3.6.0 has no riscv64-specific branch and falls through to its portable generic/no-asm C path (same path it already uses for s390x/ppc64le). Verified live under
quay.io/pypa/manylinux_2_39_riscv64: GMP and MPFR configure/build/install cleanly, and FLINT's own configure + build compiles cleanly through its core modules on riscv64.Matrix: cp312/cp313/cp314/cp314t (default).
CIBW_TEST_COMMANDuses upstream's own built-in self-test runner (python -m flint.test -q).License: MIT (python-flint itself); wheel bundles LGPL-3.0-or-later GMP/MPFR/FLINT, handled by upstream's own unmodified repair-wheel license step - no
gpl_sourcesjob needed since we build from pristine upstream tarballs, not distro packages.
