-/* The macros defined here use the timestamp counter in i586 and up versions
-   of the x86 processors.  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.
-
-   This version is for the i686 processors.  The difference to the i586
-   version is that the timerstamp register is unconditionally used.  This is
-   not the case for the i586 version where we have to perform runtime test
-   whether the processor really has this capability.  We have to make this
-   distinction since the sysdeps/i386/i586 code is supposed to work on all
-   platforms while the i686 already contains i686-specific code.
-
-   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.
