Source: xsimd Followup-For: Bug #1029568 The source of the armhf test error is actually the -mfpu=neon added explicitly in debian/rules to DEB_CXXFLAGS_MAINT_APPEND on armhf.
Remove this flag, then armhf tests pass. As far as other arches go, in general they should pass tests now (running scalar tests). I checked that tests pass on ppc64 and mipsel, for instance. powerpc failed because it does not have "-march=native". https://github.com/xtensor-stack/xsimd/pull/296/files fixed that for ppc64, but replacing the "ppc64" reference in tests/CMakeLists.txt with "ppc*" simply results in 0 tests running on powerpc (so no point testing it).
