-/* 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_NOW: place timestamp for current time in variable given as
-     parameter.
-
-   - HP_TIMING_DIFF: compute difference between two times and store it
-     in a third.  Source and destination might overlap.
-
-   - HP_TIMING_ACCUM_NT: add time difference to another variable, without
-     being thread-safe.
-
-   - 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.
