ppc64 is an identifier commonly used within the 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.
