- Crunching is one thing, compiling another. Its much easier to decrunch a
- program than
- to translate the whole code. Just think about starting a Windows program,
- which takes
- seconds to load the right parts, and to modify the code to run at a
- specific location in
- the memory (what else has to be done there? don't know).
- And we don't want to get as slow as Windows, won't we?
-
- But I think this discussion is obsolete when the PPC Amigas are getting
- the mostly used
- machines. It's much more user friendly to offer two executables, one for
- 68K, one for PPC.
- And since most software is shipped on CD right now, it won't cost more
- than a single recompile
- with different target options (with such a compiler in mind).
