- 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.

-/* long double [fp1,fp2] nearbyintl (long double x [fp1,fp2])
- IEEE 1003.1 nearbyintl function. nearbyintl is simular to the rintl
- but does raise the "inexact" exception. This implementation is
- based on rintl but explicitly maskes the inexact exception on entry
- and clears any pending inexact before restoring the exception mask
- on exit.
-
- 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 are two cases:
- 1) |x| < 2**52, all the integer bits are in the high double.
- floor the high double and set the low double to -0.0.
- 2) |x| >= 2**52, Rounding involves both doubles.
- See the comment before lable .L2 for details.

- HP_TIMING_DIFF macro.
-
- - HP_TIMING_DIFF: compute difference between two times and store it
- in a third. Source and destination might overlap.
-
- - HP_TIMING_ACCUM: add time difference to another variable. This might
- be a bit more complicated to implement for some platforms as the
- operation should be thread-safe and 64bit arithmetic on 32bit platforms
- is not.
-
- - HP_TIMING_ACCUM_NT: this is the variant for situations where we know
