    - 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_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
