ISTR that FPA floating point couldn't be used in modules, something to

I don't think that's the case (anymore?). The PS3 driver (which was btw
developed with gccsdk 4) is using FPA floating point code and works fine
on RISC OS 4/5 (well we did find a nasty and tricky FPEmulator stack
related problem which got eventually fixed).
That may be difficult to get implemented in the DDE C compiler! But, yes
that would mean that APCS-32 support wouldn't have to be added to GCC 10
just to support modules.
...and also for normal applications using the SharedCLibrary, right ?
I've longtime lost my believe that we should try to keep on using
APCS-32 (https://www.riscos.info/pipermail/gcc/2012-October/005856.html)
for building RO code. And would it really be that difficult to support
EABI in the DDE C compiler or is this just speculation ?
