# outside this file.

# Power PC returns powerpc for Big Endian. This was not changed when Little
# Endian support was added to the 64-bit architecture. The 64-bit Little
# Endian systems explicitly state le in the host_cpu. For clarity in the
# Valgrind code, the ARCH_MAX name will state LE or BE for the endianness of
# the 64-bit system. Big Endian is the only mode supported on 32-bit Power PC.
# The abreviation PPC or ppc refers to 32-bit and 64-bit systems with either
# Endianness. The name PPC64 or ppc64 to 64-bit systems of either Endianness.
# The names ppc64be or PPC64BE refer to only 64-bit systems that are Big
