This would have to be done with the arm-elf-gcc toolchain, because the Codewarrior v9 toolchain appears to statically link all armlet floating point operations with a closed source fp library. However the arm-elf-gcc toolchain appears to compile fp traps, which seem to be around 2x to 4x slower than using fp library calls. So the fdlibm solution would still perform significantly better. IMHO. YMMV.
