+ cannot make function calls.

+/* 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] floorl (long double x [fp1,fp2])
+ IEEE 1003.1 floor 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 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.
