[Qemu-devel] [V2 PATCH 0/6] Refactor AES Instructions

[Tom Musta]

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.

V2: updated patch 05/06 per Richard Henderson's review (const pointer to const)

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
