M68k -> OS4-PPC glue code is easy enough to generate using fdtrans: fdtrans -c blah_lib.sfd But if I try to do this for a .sfd that includes definitions of WarpOS PPC functions in the jumptable it complains about the "==abi" command used in the .sfd file. I'm guessing I will have to do them manually somehow or write a better fdtrans that can do them for me but then I need to know what kind of ABI that WarpOS uses, like is it same as OS4 but with library base in r3 instead of interface pointer or is it something completely different and if so what?
