-/* Target hook to return the cover classes for Integrated Register Allocator.
-   Cover classes is a set of non-intersected register classes covering all hard
-   registers used for register allocation purpose.  Any move between two
-   registers of a cover class should be cheaper than load or store of the
-   registers.  The value is array of register classes with LIM_REG_CLASSES used
-   as the end marker.
-
-   We need two IRA_COVER_CLASSES, one for pre-VSX, and the other for VSX to
-   account for the Altivec and Floating registers being subsets of the VSX
-   register set under VSX, but distinct register sets on pre-VSX machines.  */
