- * Get/set all the altivec registers vr0..vr31, vscr, vrsave, in one go.
- * The transfer totals 34 quadword.  Quadwords 0-31 contain the
- * corresponding vector registers.  Quadword 32 contains the vscr as the
- * last word (offset 12) within that quadword.  Quadword 33 contains the
- * vrsave as the first word (offset 0) within the quadword.
- *
- * This definition of the VMX state is compatible with the current PPC32
- * ptrace interface.  This allows signal handling and ptrace to use the
- * same structures.  This also simplifies the implementation of a bi-arch
- * (combined (32- and 64-bit) gdb.
