| New Amithlon 1.29 update available : Comment 45 of 73 | ANN.lu |
| Posted by Bernie Meyer on 12-Mar-2004 14:29 GMT | In reply to Comment 44 (Anonymous):
There are two answers:a) No, you'd have to agree on one endianness; As your existing executables are big-endian, you'd have to make your native OS use big-endian, too. Martin Blom's big-endian x86 gcc port shows that that's no problem at all; And if you just want that last bit of performance, nobody stops you from using little-endian for everything except data exchanged with big-endian code.b) Yes, as long as you get to define the API accordingly. Of course, that's very much not the case when talking about existing 68k executables, so it doesn't really apply.So in general, yes, you run into trouble when you want to thunk between two existing parts, one big and one little-endian, which are supposed to share data and were not designed with endianness-agnosticity in mind. Which is why just adding a 68k emulator to AROS/x86 won't work.On the other hand, as soon as you get to design and write at least one of the parts, the problem becomes pretty much a non-issue, both performance and complexity-wise. Which would have been the case for, say, step-by-step migrating from 68k-AmigaOS-in-Amithlon to big-endian-x86-AmigaOS-in-Amithlon.It would be interesting to compile AROS/x86 in big-endian, and then add a 68k emulator. But I'd feel much more confident about that if I knew that AROS can successfully be compiled for PPC, and thus has avoided any endianness-assumptions... |
