Hi, Grab http://crunch.ivey.uwo.ca/khendricks/PPC_docs.tar.gz There is an old ABI document.
Please note. PPC 32 does not follow the published ABI all of the time: 1. does not return small structures (size of 8 or less) in registers 2. does not pass floating point signals as doubles aligned to 8 on the outgoing parameter stack. Have fun!
