Fix variable 'time' may be used uninitialized warnings with '-O3' option and check validity of used warmup rounds parameter value. Signed-off-by: Matias Elo <matias.elo@nokia.com>
Replace 64-bit divisions in _odp_time_to_ns() and _odp_time_from_ns() with precomputed multiply-and-shift operations using 128-bit intermediate values. Since the timer frequency is constant after init, the required constants are computed once during _odp_time_init_global() and used for all subsequent conversions. This eliminates two divisions and a branch from each conversion call. Signed-off-by: Matias Elo <matias.elo@nokia.com>
