#BONUS intrinsics that might be useful

[p0nce]

Add one here every time you wish for one:

• [ ] _mm_cvtpd_epi64 that would convert 2x double using MXCSR would speed up things for arm and non-avx x86 => actually a AVX512DQ + AVX512VL existing instruction
• [x] _mm_abs_ps
• [x] _mm_movemask_epi16
• [ ] _mm_cmpge_epi8
• [x] _mm_cmpge_epi16 (twice)
• [ ] _mm_cmple_epi8
• [x] _mm_cmple_epi16
• [x] _mm_not_si128
