+/* 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.

+/* 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.

+/* The macros defined here use the powerpc 64-bit time base register.
+   The time base is nominally clocked at 1/8th the CPU clock, but this
+   can vary.
+
+   The list of macros we need includes the following:
+
+   - HP_TIMING_AVAIL: test for availability.
+
+   - HP_TIMING_INLINE: this macro is non-zero if the functionality is not
+     implemented using function calls but instead uses some inlined code
+     which might simply consist of a few assembler instructions.  We have to
+     know this since we might want to use the macros here in places where we
+     cannot make function calls.
+
+   - hp_timing_t: This is the type for variables used to store the time
+     values.
+
+   - HP_TIMING_ZERO: clear `hp_timing_t' object.
+
+   - HP_TIMING_NOW: place timestamp for current time in variable given as
+     parameter.
+
+   - HP_TIMING_DIFF_INIT: do whatever is necessary to be able to use the
+     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
+     there are no threads involved.
+
+   - HP_TIMING_PRINT: write decimal representation of the timing value into
+     the given string.  This operation need not be inline even though
+     HP_TIMING_INLINE is specified.
