  Description     : Microlibrary for counting CPU cycles

libcpucycles understands machine-level cycle counters for amd64 (both PMC and
TSC), arm32, arm64 (both PMC and VCT), mips64, ppc32, ppc64, riscv32, riscv64,
sparc64, and x86. libcpucycles also understands four OS-level mechanisms, which
give varying levels of accuracy: mach_absolute_time, perf_event,
CLOCK_MONOTONIC, and, as a fallback, microsecond-resolution gettimeofday.

When the program first calls cpucycles(), libcpucycles automatically benchmarks
the available mechanisms and selects the mechanism that does the best job.
Subsequent cpucycles() calls are thread-safe and very fast. An accompanying
cpucycles-info program prints a summary of cycle-counter accuracy.
