-/* The macros defined here use the timestamp counter in IA-64.  They
-   provide a very accurate way to measure the time with very little
-   overhead.  The time values themself have no real meaning, only
-   differences are interesting.
-
-   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.
