Function core::arch::riscv64::sha512sum0

pub unsafe fn sha512sum0(rs1: u64) -> u64

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on RISC-V RV64 and target feature zknh only.

Implements the Sum0 transformation function as used in the SHA2-512 hash function [49] (Section 4.1.3).

This instruction is supported for the RV64 base architecture. It implements the Sum0 transform of the SHA2-512 hash function. [49]. This instruction must always be implemented such that its execution latency does not depend on the data being operated on.

Safety

This function is safe to use if the zknh target feature is present.
