[Qemu-devel] [PATCH 0/6] Refactor AES Instructions |
Date: |

This patch series addresses concerns raised by Richard Henderson regarding
redundant
copies of Advanced Encryption Standard (AES) data and code (see
http://lists.nongnu.org/archive/html/qemu-devel/2014-02/msg04391.html).
The patches declare commonly used AES tables in the include/qemu/aes.h header
file
and define the tables in util/aes.c, thus eliminating redundant copies.
Minor refactorization of the i386 and ARM instruction models are made to utilize
this common support. The newly added PowerPC instructions are completely
rewritten and look much more like the i386 equivalents; a substantial amount of
code is eliminated.
Tom Musta (6):
util: Add S-Box and InvS-Box Arrays to Common AES Utils
util: Add AES ShiftRows and InvShiftRows Tables
util: Add InvMixColumns
target-i386: Use Common ShiftRows and InvShiftRows Tables
target-arm: Use Common Tables in AES Instructions
target-ppc: Refactor AES Instructions
