I would like to "emulate" the fpu in the kernel so I can compile glibc and everything else with fpu instructions to save ram. I have been told however that there are "issues" with this approach, and the only way to go is to emulate the fpu in the kernel and compile everything with soft float. What I want to know is what these issues are? (accuracy,segment_fault,etc..)
