Interpretation when omitted

None

[Detailed description]

-

This option generates the recipf.d and recipf.s 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.

[Remark]

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.
