The @samp{org.gnu.gdb.nds32.core} feature is required for NDS32
|

targets. It should contain at least registers @samp{r0} through

|
||||
and @samp{pc}.

The @samp{org.gnu.gdb.nds32.fpu} feature is optional. If present,
|
||||
it should contain 64-bit double-precision floating-point registers
|
||||
@samp{fd0} through @emph{fdN}, which should be @samp{fd3}, @samp{fd7},
|
||||
@samp{fd15}, or @samp{fd31} based on the FPU configuration implemented.
|

|
||||
@emph{Note:} The first sixteen 64-bit double-precision floating-point
|
||||
registers are overlapped with the thirty-two 32-bit single-precision
|
||||
floating-point registers. The 32-bit single-precision registers, if
|
||||
not being listed explicitly, will be synthesized from halves of the
|
||||
overlapping 64-bit double-precision registers. Listing 32-bit
|
||||
single-precision registers explicitly is deprecated, and the
|
||||
support to it could be totally removed some day.
