🔬 This is a nightly-only experimental API. (stdsimd)
This is supported on x86-64 and target feature avx512vbmi2 only.
Expand description

Concatenate packed 16-bit integers in a and b producing an intermediate 32-bit result. Shift the result left by the amount specified in the corresponding element of c, and store the upper 16-bits in dst using writemask k (elements are copied from a when the corresponding mask bit is not set).
