Aurelien Jarno 65cf1f65be target-ppc: fix vcipher, vcipherlast, vncipherlast and vpermxor
For vector instructions, the helpers get pointers to the vector register
in arguments. Some operands might point to the same register, including
the operand holding the result.

When emulating instructions which access the vector elements in a
non-linear way, we need to store the result in an temporary variable.

This fixes openssl when emulating a POWER8 CPU.

This patch refactors the PowerPC Advanced Encryption Standard (AES) instructions
to use the common AES tables (include/qemu/aes.h).

Specifically:
    - vsbox is recoded to use the AES_sbox table.
    - vcipher, vcipherlast and vncipherlast are all recoded to use the optimized
      AES_t[ed][0-4] tables.
    - vncipher is recoded to use a combination of InvS-Box, InvShiftRows and
      InvMixColumns tables.  It was not possible to use AES_Td[0-4] due to a
      slight difference in how PowerPC implements vncipher.

Tom Musta 818692ff95 target-ppc: Altivec 2.07: Change Bit Masks to Support 64-bit Rotates and Shifts
Existing code in the VROTATE, VSL and VSR macros for the Altivec rotate and shift
helpers uses a formula to compute a bit mask used to extract the rotate/shift
amount from the VRB register.  What is desired is:

    mask = (1 << (3 + log2(sizeof(element)))) - 1

but what is implemented is:

    mask = (1 << (3 + (sizeof(element)/2))) - 1

This produces correct answers when "element" is uint8_t, uint16_t or uint_32t.  But
it breaks down when element is uint64_t.

This patch corrects the situation.  Since the mask is known at compile time, the
macros are changed to simply accept the mask as an argument.

Subsequent patches in this series will add double-word variants of rotates and
shifts and thus take advantage of this fix.

This VMUL_DO macro provides support for the various vmule* and vmulo*

The existing macro works correctly for the existing instructions (8-bit,

This patch adds an explicit cast to the multiplicands, forcing them to be
of the target element type.  This is required for the forthcoming patches
