I'd like to hear more about this.
Sounds like supporting "hard float" was/is way more complicated with ARM
than the hard/soft float support back in the pre-Pentium days. I still
have a 486 "SX" which requires math emulation. But on INTeL x86 series HW,
that's a boolean flag when building the kernel. No need to re-compile the
apps. (Unless I have missed something profound.)
