+The @samp{org.gnu.gdb.power.htm.spr} feature is optional.  It should
+contain registers @samp{tfhar}, @samp{texasr} and @samp{tfiar}, all
+64-bit wide.

+The @samp{org.gnu.gdb.power.htm.core} feature is optional.  It should
+contain the checkpointed general-purpose registers @samp{cr0} through
+@samp{cr31}, as well as the checkpointed registers @samp{clr} and
+@samp{cctr}.  These registers may all be either 32-bit or 64-bit
+depending on the target.  It should also contain the checkpointed
+registers @samp{ccr} and @samp{cxer}, which should both be 32-bit
+wide.

+The @samp{org.gnu.gdb.power.htm.fpu} feature is optional.  It should
+contain the checkpointed 64-bit floating-point registers @samp{cf0}
+through @samp{cf31}, as well as the checkpointed 64-bit register
+@samp{cfpscr}.

+checkpointed registers @samp{cvscr} and @samp{cvrsave}, both 32-bit
+wide.

+will combine these registers with the checkpointed floating point
+registers (@samp{cf0} through @samp{cf31}) and the checkpointed
+altivec registers (@samp{cvr0} through @samp{cvr31}) to present the
+128-bit wide checkpointed vector-scalar registers @samp{cvs0} through
+@samp{cvs63}.  Therefore, this feature requires both

+@samp{org.gnu.gdb.power.htm.fpu}.

+The @samp{org.gnu.gdb.power.htm.ppr} feature is optional.  It should
+contain the 64-bit checkpointed register @samp{cppr}.
+
+The @samp{org.gnu.gdb.power.htm.dscr} feature is optional.  It should
+contain the 64-bit checkpointed register @samp{cdscr}.
+
+The @samp{org.gnu.gdb.power.htm.tar} feature is optional.  It should
+contain the 64-bit checkpointed register @samp{ctar}.
