This is ancient code that was meant to emulate only load/stores/fmr without the rest of the emulation. The goal was to be able to boot userspace that was compiled without -msoft-float to *some* extent (bcs it would potentially use fp load/stores for things like memcpy) on small CPUs where the kernel footprint was critical. It's been obsolete for a while now.
