-description = """valid 68020/68030 code can use `fsave`/`frestore` instructions to save/restore the state of an external 68881/68882 but currently QEMU only allows these instructions on 68040 and everyone else gets an f-line exception.
-
-I guess something like this to allow frestore/fsave. m68k programmers reference manual says they are 68881/68882/68040 and there don's seem to be any differences.
