2 * Contains the definition of registers common to all PowerPC variants.
3 * If a register definition has been changed in a different PowerPC
4 * variant, we will case it in #ifndef XXX ... #endif, and have the
5 * number used in the Programming Environments Manual For 32-Bit
6 * Implementations of the PowerPC Architecture (a.k.a. Green Book) here.
