Hopefully _mm256_atan2_ps isn't in a header provided by GCC ... hmm, ICC seems to have it in immintrin.h: /suse/matz/bin/2018.1/include/icc/immintrin.h:extern __m256 __ICL_INTRINCC _mm256_atan2_ps(__m256, __m256); and also: /suse/matz/bin/2018.1/include/dvec.h: friend F32vec8 atan2(const F32vec8 &a, const F32vec8 &b) { return _mm256_atan2_ps(a, b); } not sure if we have a way to provide the intrinsic in a reasonable way from GCC, doing auto-dispatch to libmvec or alternatively open-coding elementwise?
