Yes, there are various degrees of those, but most of them should be
FPU-less. So FPU-emulation details would be interesting.
In case of Linux there are 3 variants:
NWFPE: default
FastFPE: only 32-bit mantissa, 4-8x faster than NWFPE
gcc -msoft-float: no FP instructions, direct calls. This
changes calling convention, so requires that all
code is compiled with this.
Jim, do you happen to use FastFPE?
