| H A D | sm4-ce-asm.h | ce41fefd Thu Oct 27 01:54:58 CDT 2022 Tianjia Zhang <tianjia.zhang@linux.alibaba.com> crypto: arm64/sm4 - refactor and simplify CE implementation
This patch does not add new features, but only refactors and simplifies the
implementation of the Crypto Extension acceleration of the SM4 algorithm:
Extract the macro optimized by SM4 Crypto Extension for reuse in the
subsequent optimization of CCM/GCM modes.
Encryption in CBC and CFB modes processes four blocks at a time instead of
one, allowing the ld1 instruction to load 64 bytes of data at a time, which
will reduces unnecessary memory accesses.
CBC/CFB/CTR makes full use of free registers to reduce redundant memory
accesses, and rearranges some instructions to improve out-of-order execution
capabilities.
