I'm computing 2 floats per lane and want to store them interleaved, like so:
foreach (i = 0 ... _n)
{
// do some work to compute data0, data1...
*(_b->m_data + 2 * i + 0) = data0;
*(_b->m_data + 2 * i + 1) = data1;
}
Resulting in a scatter.
Using C++ vector intrinsics (_mm256_unpacklo_ps, _mm256_unpackhi_ps, 2x
_mm256_permute2f128_ps) I can interleave data0 and data1 and generate
vector stores.
Is there a way to do this in ISPC?
