The fix in numpy/meson#12 for ASIMD*(32-bit) compile-time feature detection revealed a new build error on aarch32 platforms: ImportError: /numpy/build-install/usr/lib/python3/dist-packages/numpy/_core/ _multiarray_umath.cpython-310-arm-linux-gnueabihf.so: undefined symbol: _ZN2np7highway10qsort_simd11QSort_ASIMDIjEEvPT_i This patch prevents platform detection constants of Highway from being exposed across translation units with different compiler flags (baseline). This approach eliminates detection mismatches that were causing symbol resolution failures in the Highway QSort implementation.
