21.4.7 PowerPC
--------------
When GDB is debugging the PowerPC architecture, it provides a set of
pseudo-registers to enable inspection of 128-bit wide Decimal Floating
Point numbers stored in the floating point registers. These values must
be stored in two consecutive registers, always starting at an even
register like 'f0' or 'f2'.
The pseudo-registers go from '$dl0' through '$dl15', and are formed
by joining the even/odd register pairs 'f0' and 'f1' for '$dl0', 'f2'
and 'f3' for '$dl1' and so on.
For POWER7 processors, GDB provides a set of pseudo-registers, the
64-bit wide Extended Floating Point Registers ('f32' through 'f63').
