     31 The Imagination Technologies Meta architecture is implemented in a
     32 number of versions, with each new version adding new features such as
     33 instructions and registers. For precise details of what instructions
     34 each core supports, please see the chip's technical reference manual.

     84 Registers can be specified either using their mnemonic names, such as
     85 @samp{D0Re0}, or using the unit plus register number separated by a @samp{.},
     86 such as @samp{D0.0}.
