-/* long double [fp1,fp2] ceill (long double x [fp1,fp2])
- IEEE 1003.1 ceil function.
-
- 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 ceiled
- to represent a normal ceiling 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 ceiling.
-
- For long double there are two cases:
- 1) |x| < 2**52, all the integer bits are in the high double.
- ceil the high double and set the low double to -0.0.
- 2) |x| >= 2**52, ceiling involves both doubles.
- See the comment before lable .L2 for details.

-/* 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
- following algorithm:
-
- tau = floor(x_high/TWO52);
- x0 = x_high - tau;
- x1 = x_low + tau;
- r1 = rint(x1);
- y_high = x0 + r1;
- y_low = x0 - y_high + r1;
