--- Comment #15 from niva at niisi dot msk.ru ---
We are using MIPS target and we are extremely interested in the 
solution formulated in
https://gcc.gnu.org/ml/gcc/2015-04/msg00239.html:

"Ideally I'd like a guarantee
that FP registers will never be used unless a floating point type is
present in the source "

In fact we'd like to have an option which disables
use of FP registers and makes the compiler to issue an
error if any FP operation occurs in the program.
