-+	  This option lets you disable the built-in MIPS FPU (Coprocessor 1)
-+	  emulator, which handles floating-point instructions on processors
-+	  without a hardware FPU.  It is generally a good idea to keep the
-+	  emulator built-in, unless you are perfectly sure you have a
-+	  complete soft-float environment.  With the emulator disabled, all
-+	  users of float operations will be killed with an illegal instr-
-+	  uction exception.
