Try use self hosted linux runner to build html and latexpdf to check for errors.
Trying to use the build artifact didn't seem to work, so just run it on its own.
Upload docs/build folder as artifact to enable review without having to build
locally. Note: doesn't include verific, so will differ slightly from final
published docs.
* `misc/__init__.py`:
* checks if there's a `yosys-abc` in the same directory - if yes, sets the variable `sys._pyosys_abc`
* checks if there's a `share` in the same directory - if yes, sets the variable `sys._pyosys_share_dirname`
* `yosys.cc::init_share_dirname`: check for `sys._pyosys_share_dirname`, use it at the highest priority if Python is enabled
* `yosys.cc::init_abc_executable_name`: check for `sys._pyosys_abc`, use it at at the highest priority if Python is enabled
* `Makefile`: add new target, `share`, to only create the extra targets
* `setup.py`: compile libyosys.so, yosys-abc and share, and copy them all as part of the pyosys build
* `test/arch/ecp5/add_sub.py`: ported `add_sub.ys` to Python to act as a test for the share directory and abc with Python wheels, used in CI
Since `docs/prep` is a prerequisite of `docs`, and should be the *only* prerequisite, calling `make docs` could end up hiding a problem with files missing from the uploaded artifact. Instead, call `make` from the docs directory which should be closer to what will run on RTDs.
* wheel versions now replace `+` with `.post` to match spec at https://packaging.python.org/en/latest/specifications/version-specifiers/
* CI updates:
* Bump action versions
* Disabled Windows for now and documented why
* Added a new job to upload all wheels
* Added new variable, `PYPI_INDEX`: fallback 'https://pypi.org/' if unset
* Added new secret, `PYPI_TOKEN`
* .editorconfig now uses 2 spaces for YML (it kept setting mine to tabs
and GitHub Actions doesn't like that)
* Update manylinux images
* FFI now built as a per-platform static library
* Explicitly set minimum macOS deployment target, use clang on macOS
* Try enabling Windows (as an experiment)
* Disable aarch64-linux, aarch64-windows
* Created `setup.py`: Python package manifest to build `pyosys` wheels with a custom extension to build and include `libyosys.so` using Make
* `.gitignore`: Added byproducts of the Python wheel build process
* `Makefile`: Added `-undefined dynamic_lookup` to `libyosys.so` so missing symbols can be resolved by importing into a Python interpreter
* `kernel/yosys.cc`: Gated `PyImport_AppendInittab` with `!Py_IsInitialized`; as of Python 3.12, the interpreter is already initialized and `PyImport_AppendInittab` would cause an exception to be raised
* Created `wheels.yml`: CI workflow for building wheels for CPython on:
* Linux (glibc, musl) and Darwin
* x86-64 and arm64
Docs jobs should not skip on concurrent jobs (in case a non-docs job is already
running, such as when a commit has been tagged for docs-preview). However, a
successful `test-verific` can allow for a future docs job to skip testing and go
straight to the preview.
