...which probably does not exist, so this is a valid and working approach, although incomplete. Appropriate code for other archi- tectures can be added later. At least for MIPS. Or is there an ARM processor with 64 bit data bus?
How did you use "double" and it did not work? Please give example of the work you tried...
It did not work in the intended sense as the compiler did not generate any FP instructions - which is to be expected as we explicitely tell him to use -msoft-float.
