This commit is for Bugzilla 334384. The Bugzilla contains patch 1 of 3
to add PPC64 LE support. The other two patches can be found in Bugzillas
334834 and 334836. The commit does not have a VEX commit associated with it.
POWER PC, add initial Little Endian support
The IBM POWER processor now supports both Big Endian and Little Endian.
This patch renames the #defines with the name ppc64 to ppc64be for the BE
specific code. This patch adds the Little Endian #define ppc64le to the
Additionally, a few functions are renamed to remove BE from the name if the
function is used by BE and LE. Functions that are BE specific have BE put
in the name.
The goals of this patch is to make sure #defines, function names and
variables consistently use PPC64/ppc64 if it refers to BE and LE,
PPC64BE/ppc64be if it is specific to BE, PPC64LE/ppc64le if it is LE
specific. The patch does not break the code for PPC64 Big Endian.
The test files memcheck/tests/atomic_incs.c, tests/power_insn_available.c
and tests/power_insn_available.c are also updated to the new #define
definition for PPC64 BE.
