Calling conventions

Linux

  • Linux on PPC32 uses the The PowerPC SystemV ABI specification.
  • On 64-bit PowerPC, there are two calling conventions. One is the ELF v1 ABI used on almost all big-endian systems, which are similar to AIX and use function descriptors.
  • The other 64-bit PowerPC calling convention is the ELF v2 ABI, used by little-endian systems and a few big-endian systems. This ABI has no function desxcriptors and is closer to the PPC32 ABI.
