It inlines the UnscaledCycleClock::Now() which is a single RTDSC op for x86, and likewise inlines CycleClock::Now() for x86. The inlining should mostly have secondary benefits such as reducing spills on outlined calls.\n\nLTO may eventually hoist these functions inline for the hotspots, but it doesn\u0027t hurt to default inline this for all builds and let the compiler decide on the first pass.\n\nThe perlab benchmark is noisy for the plain BM_Now, but the other benchmarks and the run on my local machine are clear.\n\n------------- Local Benchy Benchmark\nname old cpu/op new cpu/op delta\nBM_Now 3.41ns ± 1% 2.30ns ± 2% -32.52% (p\u003d0.000 n\u003d50+50)\nBM_NowWithRegisterPresure 4.96ns ± 2% 4.19ns ± 2%
