I doubt various C++ compilers are this compatible, even if
they follow the
same ABI.
They aren't. For instance, GCC use arbitrary precision FB, and
LLVM uses 128
bits soft floats in their innards.
Looks like LLVM had the same idea as myself.
Anyhow, this pretty much destroys the idea that I have proposed
some sort of cowboy FP that's going to wreck FP programs.
(What is arbitrary precision FB?)
Typo: arbitrary precision FP. Meaning some soft float that grows
as big as necessary to not lose precision à la BitInt but for
floats.
