need this, you may wish to put the command in your @value{GDBINIT}
file). This tells @value{GDBN} how to find the return value of
functions which return floating point values. It also allows
@value{GDBN} to avoid saving the floating point registers when calling

functions on the board. If you are using a floating point coprocessor
with only single precision floating point support, as on the @sc{r4650}
processor, use the command @samp{set mipsfpu single}. The default
double precision floating point coprocessor may be selected using
@samp{set mipsfpu double}.
In previous versions the only choices were double precision or no
floating point, so @samp{set mipsfpu on} will select double precision
and @samp{set mipsfpu off} will select no floating point.
As usual, you can inquire about the @code{mipsfpu} variable with
@samp{show mipsfpu}.
