If the application is really using FP instructions a lot, then there
is a huge difference between using soft-float and MATH_EMU; I
remember test cases where soft-float was faster by factors of
500...1000.

No, we never tried that. Sounds scary to me.

The connection between the language in which we think/program and the
problems and solutions we can imagine is very close. For this  reason
restricting  language  features  with  the intent of eliminating pro-
grammer errors is at best dangerous.
