I implemented floating point by emitting coprocessor instructions. But there are only few ARMs with hardware FPUs. The Linux kernel shipped with my StrongArm PDA has a FPA-FPU emulator. On this system it was necessary to use FPA instructions to be able to call library functions that return floating point values. Some time later I changed the code to support EABI Linux machines. I expected these to have a VFP-FPU (or emulator). But the proper way to implement floating point on EABI machines is to call the standardized __aeabi_* library functions. I didn't implement this yet because I was not shure if TinyCC can cope with registers being able to contain integers and floating point values. I don't think I will have time to do this part until I have finished my thesis.
