| # Bit-exact CI: every push/PR must pass all 792 IEEE-754 tests. | |
| # | |
| # Requirements driving the setup: | |
| # - numpy must be pip-installed (its bundled OpenBLAS exposes sdot_64_ / | |
| # cblas_sgemm64_ / __svml_exp8 etc. that numpycpp resolves via dlsym) | |
| # - AVX-512 hardware is required at runtime (-mavx512f compile flag + | |
| # __attribute__((target)) guards; GitHub ubuntu-latest uses Intel Xeon | |
| # which supports AVX-512) | |
| # - pybind11, Eigen3, OpenMP needed to build the test extension module | |
