This option generates the recipf instructions.
If this option is specified more than once, it has the same meaning as when this option is specified once. No warning is output in this case. |
If usage of the FPU is not enabled by the -Xcpu option or -Xfloat option, this option is ignored. No warning is output in this case. |
If the recipf instructions are generated by this option, the operation result may differ from that when this option is not specified.
Since a recipf instruction always triggers an incorrect operation exception of the FPU, FPU exception processing should be set appropriately.
