bad usage of AVX2 instruction without checking availability of the instruction set

pascalgiorgi opened this issue · 0 comments

In the file simd128_float.inl some of the pack functions use the instruction _mm_permute_ps that belongs to AVX instruction set.
The code must ensure that this instruction set is available before calling. A fallback code needs to be provided when AVX is not available.
