Ppc64

ppc64 is an identifier commonly used within the GNU/Linux, GNU Compiler Collection (GCC) and LLVM free software communities to refer to the target architecture for applications optimized for 64-bit big-endian PowerPC and Power ISA processors.

ppc64le is a pure little-endian mode that has been introduced with the POWER8 as the prime target for technologies provided by the OpenPOWER Foundation, aiming at enabling porting of the x86 Linux-based software with minimal effort.

Details
These two identifiers are frequently used when compiling source code to identify the target architecture.

64-bit Power and PowerPC processors are the following:
 * PowerPC 620
 * RS64 – Apache, RS64-II Northstar, RS64-III Pulsar/IStar, and RS64-IV SStar
 * POWER3 and POWER3-II
 * POWER4 and POWER4+
 * PowerPC 970, 970FX, 970MP and 970GX
 * POWER5 and POWER5+
 * PPE in Cell BE, PowerXCell 8i and Xenon.
 * PWRficient
 * POWER6 and POWER6+
 * POWER7 and POWER7+
 * A2, A2I (used in the Blue Gene/Q) and A2O
 * PowerPC e5500 core based
 * PowerPC e6500 core based
 * POWER8 – P8-6c Murano, P8-12c Turismo and Venice, P8E (with NVLink) and CP1
 * POWER9 – P9C Cumulus, P9N Nimbus and P9 AIO Axone
 * Power10
 * Microwatt, open source soft core
 * Chiselwatt, open source soft core

Defunct 64-bit PowerPC processors are the Motorola G5 and PowerPC e700.
