Changelog for ghc-criterion-measurement-0.1.3.0-bp155.2.15.x86_64.rpm :

* Sat Jul 10 2021 psimonsAATTsuse.com- Update criterion-measurement to version 0.1.3.0. 0.1.3.0
* Change `criterion_rdtsc` to return `mach_absolute_time` on macOS. This is a portable way of returning the number of CPU cycles that works on both Intel- and ARM-based Macs.
* Change `criterion_gettime` to use `clock_gettime_nsec_np` instead of `mach_absolute_time` on macOS. While `mach_absolute_time` has nanosecond resolution on Intel-based Macs, this is not the case on ARM-based Macs, so the previous `mach_absolute_time`-based implementation would return incorrect timing results on Apple silicon. There are two minor consequences of this change:
* `criterion-measurement` now only supports macOS 10.02 or later, as that is the first version to have `clock_gettime_nsec_np`. As macOS 10.02 was released in 2002, this is unlikely to affect users, but please speak up if this is a problem for you.
* As `clock_gettime_nsec_np` does not require any special initialization code, `criterion_inittime` is now a no-op on macOS. If you manually invoke the `getTime` function in your code, however, it is still important that you `initializeTime` beforehand, as this is still required for the Windows implementation to work correctly.
* Mon Apr 26 2021 psimonsAATTsuse.com- Add criterion-measurement at version 0.1.2.0.
