...t I thought that this meant that gcc was using rdtsc, but gcc sources do not show any use of rdtsc. Next I suspected bash, but it doesn''t either. Finally, it appears that the calls are occurring from glibc, and searching for uses of rdtsc, I found that glibc has its own implementation of clock_gettime that uses rdtsc directly! The manpage for clock_gettime ("man 3 clock_gettime") has a lengthy caveat about using clock_gettime on an SMP system BUT provides a mechanism to test to see if your SMP system is safe, clock_getcpuclockid(0). See for example (near the end): http://linux.die.ne...

configure uses clock_gettime to check whether -lrt is needed - and don''t check other functions. With glibc 2.17 clock_gettime is part of libc, so use timer_gettime instead, which is in -lrt in old and new versions of glibc.

On my setup with glibc-2.8, benchmark_residual linkage fails with undefines references to clock_gettime(). Adding -lrt fixes that. The following is a small patch for it.
