-/* long long [r3] llround (long double x [fp1,fp2])
-   IEEE 1003.1 llroundl function.  IEEE specifies "round to the nearest
-   integer value, rounding halfway cases away from zero, regardless of
-   the current rounding mode."  However PowerPC Architecture defines
-   "round to Nearest" as "Choose the best approximation. In case of a
-   tie, choose the one that is even (least significant bit o).".
-   So we can't use the PowerPC "round to Nearest" mode. Instead we set
-   "round toward Zero" mode and round by adding +-0.5 before rounding
-   toward zero. The "Floating Convert To Integer Doubleword with round
-   toward zero" instruction handles the conversion including the
-   overflow cases and signalling "Invalid Operation".
-
-   PowerPC64 long double uses the IBM extended format which is
-   represented two 64-floating point double values. The values are
-   non-overlapping giving an effective precision of 106 bits. The first
-   double contains the high order bits of mantisa and is always rounded
-   to represent a normal rounding of long double to double. Since the
-   long double value is sum of the high and low values, the low double
-   normally has the opposite sign to compensate for the this rounding.
-
-   For long double there is 4 cases:
-   1) |x| < 2**52, all the integer bits are in the high double.
-      Round and convert the high double to long long.
-   2) 2**52 <= |x|< 2**63, Still fits but need bits from both doubles.
-      Round the low double, convert both, then sum the long long values.
-   3) |x| == 2**63, Looks like an overflow but may not be due to rounding
-      of the high double.
-      See the description following lable L2.
-   4) |x| > 2**63, This will overflow the 64-bit signed integer.
-      Treat like case #1. The fctidz instruction will generate the
-      appropriate and signal "invalid operation".

-/* The high double is > TWO52 so we need to round the low double and
-   perhaps the high double.  In this case we have to round the low
-   double and handle any adjustment to the high double that may be
-   caused by rounding (up).  This is complicated by the fact that the
-   high double may already be rounded and the low double may have the
-   opposite sign to compensate.This gets a bit tricky so we use the

-
