Based on previous experiences with FPU less Linux systems, you do not want to compile for FPU emulation (soft float) - it is dreadfully slow - you want to replace any software that relies on FPU with software that only does simple integer math.

What prevents binaries from asking the OS about the abilities of the hardware, and run code accordingly? I mean, other operating systems manage to have "fat" binaries that contain entirely different architectures, but on Amiga it is not even possible to have one binary for variations within one architecture.

This is already done in various programs for altivec/non-altivec code. The W3D_SI driver, for example, will use altivec on hardware that has it, and non-altivec code on machines that don't. The graphics library goes one step further and has copy routines that are optimized for specific processors (incl. using DMA on certain platforms). IIRC, MiniGL has a few altivec routines as well.


Good, that is how it should be.

The examples above are a bit different from simply having a fat binary with completely different compiles sitting there side-by-side. Instead, the developer himself/herself compiles different versions of just the parts that matter. I personally prefer that approach, as the sections of a program that actually benefit from altivec/SPE/whatever is usually limited.


Which is really what I meant, it should not be such a big deal, not like OS4 has this vast portfolio of abandoned native software anyhow.
