-	  This option allows threads to use the floating point registers.
-	  By default, only a single thread may use the registers.
+	  This option enables the hardware Floating Point Unit (FPU), in order to
+	  support using the floating point registers and instructions.
 
-	  Disabling this option means that any thread that uses a
-	  floating point register will get a fatal exception.
+	  When this option is enabled, by default, threads may use the floating
+	  point registers only in an exclusive manner, and this usually means that
+	  only one thread may perform floating point operations.
+
+	  If it is necessary for multiple threads to perform concurrent floating
+	  point operations, the "FPU register sharing" option must be enabled to
+	  preserve the floating point registers across context switches.
+
+	  Note that this option cannot be selected for the platforms that do not
+	  include a hardware floating point unit; the floating point support for
+	  those platforms is dependent on the availability of the toolchain-
+	  provided software floating point library.
