Name:           python-llvmlite
Version:        0.42.0
Release:        %{autorelease}
Summary:        Lightweight LLVM Python binding for writing JIT compilers

# The entire source is BSD-2-Clause, except:
#   - The bundled versioneer.py, and the _version.py it generates (which is
#     packaged) is LicenseRef-Fedora-Public-Domain. In later versions of
#     versioneer, this becomes CC0-1.0 and then Unlicense.
#     Public-domain text added to fedora-license-data in commit
#     830d88d4d89ee5596839de5b2c1f48426488841f:
#     https://gitlab.com/fedora/legal/fedora-license-data/-/merge_requests/210
#   - ffi/memorymanager.{h,cpp} are Apache-2.0 WITH LLVM-exception
# Additionally, the following does not affect the license of the binary RPMs:
#   - conda-recipes/appveyor/run_with_env.cmd is CC0-1.0; for distribution in
#     the source RPM, it is covered by “Existing uses of CC0-1.0 on code files
#     in Fedora packages prior to 2022-08-01, and subsequent upstream versions
#     of those files in those packages, continue to be allowed. We encourage
#     Fedora package maintainers to ask upstreams to relicense such files.”

%global _description %{expand:
llvmlite is a project originally tailored for Numba‘s needs, using the
following approach:

  • A small C wrapper around the parts of the LLVM C++ API we need that are not
    already exposed by the LLVM C API.
  • A ctypes Python wrapper around the C API.
  • A pure Python implementation of the subset of the LLVM IR builder that we
    need for Numba.}
