It's not strictly the requirement I would impose though.  The existing
code has proven to be very hard to maintain (and the existing NaN/Inf/
denormal handling bugs are unlikely to be fixable without rewriting a
lot of it), so if a non-assembler implementation would get us to say
110...120 % of the code size of the assembler hacks we've got now, but
with a 500 % maintainability improvement, I wouldn't mourn.  Floating
point is certainly not really suitable for an ATtiny2313 anyway.
