 The benchmark suite does function call measurements using architecture-specific
 high precision timing instructions whenever available.  When such support is
-not available, it uses clock_gettime (CLOCK_PROCESS_CPUTIME_ID).  One can force
-the benchmark to use clock_gettime by invoking make as follows:
-
-  $ make USE_CLOCK_GETTIME=1 bench

-Again, one must run `make bench-clean' before changing the measurement method.

 On x86 processors, RDTSCP instruction provides more precise timing data
 than RDTSC instruction.  All x86 processors since 2010 support RDTSCP
