I suspect that this will depend on the target operating system, so the
Linux ABI
may differ from e.g. MUSIC/SP.
ABI means what? for those of us reading and trying to keep up ;) this
might even be something new to those attempting to work on such a port
task ;)
Application Binary Interface, it's the overall set of register usage
conventions, syscall numbers and so on. I'm unsure the origin of the
term but over the last ten years or so it's come into common usage for
Linux, and extended to other OSes.
For Linux on IBM mainframes, see
http://linuxvm.org/present/SHARE102/S9236uw.pdf as a starting point.
Also I've put info on assembler formats etc. at
http://wiki.lazarus.freepascal.org/Assembler_and_ABI_Resources (I needed
comparative info when looking at MIPS a few months ago), I was hoping to
add links to ABIs for each architecture but didn't get that far since
something else intervened.
