But all three existing architectures (x86, s390 and arm) already have the capability to parse the table and generate different output from that.
Yeah, we want that on powerpc too.
If the script needs to be more complex that's fine, if it can't be shared across arches that's fine, the main thing for me is that wiring up a syscall can be done by adding a single line in a single file.
Yes, that's definitely the idea, we want to make it easier for everyone. We need at least a special case for mips, which needs three separate input files (the tables are completely different) to generate four versions of the output, plus a future extension to use the generic table for their new one.
For powerpc, I'm hoping that both the table format and script can be completely generic and not need a special case that is different from the others, but if we need some extra magic to handle the SPU syscalls, we can still do that with a private script.
