Function core::arch::powerpc64::vec_slv

pub unsafe fn vec_slv(
    a: vector_unsigned_char,
    b: vector_unsigned_char,
) -> vector_unsigned_char

🔬This is a nightly-only experimental API. (stdarch_powerpc #111145)

Available on (PowerPC or PowerPC-64) and target feature power9-altivec and PowerPC-64 only.

Vector Shift Left Variable

Result value

Let v be a 17-byte vector formed from a in bytes [0:15] and a zero byte in element 16. Then each byte element i of r is determined as follows. The start bit sb is obtained from bits 5:7 of byte element i of b. Then the contents of bits sb:sb+7 of the halfword in byte elements i:i+1 of v are placed into byte element i of r.

Endian considerations

All bit and byte element numbers are specified in big-endian order. This intrinsic is not endian-neutral.
