#define TEST_CALIBRATION	(		target_ms,
			CODE
	)

Macro for test repetitions needed to benchmark in the order of milliseconds.

TEST_CALIBRATION() - This macro is used to calculate the number of repetitions needed for execution of a test routine, so that the total duration is long enough to be measured by a timer with millisecond resolution like gettimeofday(). Given an upper test duration bound, this macro will return the number of inner loop repetitions needed for benchmarking a piece of code. Estimated run time: the calibration process should take somewhat less than MIN (max_calibration_time, (target_ms * 2 * 7)) milliseconds.

• target_ms - expected total test runtime for RUNS * dups * testfunc_time
• max_calibration_time - expected upper bound for test calibration runtime In this macro, "dups" is calculated appropriately for max_calibration_time, and scaled upon return to match target_ms accordingly.
