Subject: [PATCH 07/13] SM4 optimization for ARM by ASIMD
This patch optimizes SM4 for ARM processor using ASIMD instruction
It will improve performance if both of following conditions are met:
1) Input data equal to or more than 4 blocks
2) Cipher mode allows parallelism, including ECB,CTR,GCM or CBC decryption
This patch implements SM4 SBOX lookup in vector registers, with the
benefit of constant processing time over existing C implementation.
It is only enabled for micro-architecture N1/V1. In the ideal scenario,
performance can reach up to 2.7X
When either of above two conditions is not met, e.g. single block input
or CFB/OFB mode, CBC encryption, performance could drop about 50%.
The assembly code has been reviewed internally by ARM engineer
