ppc64 is an identifier commonly used within the Linux, GNU Compiler Collection (GCC) and LLVM open-source 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.
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, PowerPC 970FX, PowerPC 970MP and PowerPC 970GX
- POWER5 and POWER5+
- PPE in Cell BE, PowerXCell 8i and Xenon.
- POWER6 and POWER6+
- POWER7 and POWER7+
- A2 used in the Blue Gene/Q compute chip
- PowerPC e5500
- PowerPC e6500
- POWER8 and CP1
