# [−][src]Function core::arch::mips::__msa_vshf_d

    pub unsafe fn __msa_vshf_d(a: v2i64, b: v2i64, c: v2i64) -> v2i64

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on MIPS and target feature `msa` only.

Vector Data Preserving Shuffle

The vector shuffle instructions selectively copy data elements from the concatenation of vectors `b` (two signed 64-bit integer numbers) and `c` (two signed 64-bit integer numbers) in to vector `a` (two signed 64-bit integer numbers) based on the corresponding control element in `a`. The least significant 6 bits in `a` control elements modulo the number of elements in the concatenated vectors `b`, `a` specify the index of the source element. If bit 6 or bit 7 is 1, there will be no copy, but rather the destination element is set to 0.
