Hi Andreas,

>which caling / runtime convention does fbsd ppc follow? The sysv4 from 
>SUN dated around september 1995? Or is it another one?

 That's the one.

>Does/should it follow this convention without any exceptions?

 The one exception is that long doubles are 64-bit and not 128-bit.
OSX/NetBSD/Linux on powerpc all use 64-bit long doubles, so it
didn't seem to make a lot of sense to follow the ABI strictly there.

later,

Peter.
