Subject: [PATCH v4 09/10] member: use accelerated CRC on riscv
Date: Sun, 22 Feb 2026 16:30:03 +0100 [thread overview]
Message-ID: <4ad0a26fa5a02032fb3e44c43c68fbc2c4af5775.1771772598.git.code@danielg0.com> (raw)
In-Reply-To: <cover.1771772598.git.code@danielg0.com>
From: Daniel Gregory <daniel.gregory@bytedance.com>
When the RISC-V Zbc (carryless multiplication) extension is present, an
implementation of CRC hashing using hardware instructions is available.
Use it rather than jhash.
