https://docs.microsoft.com/en-us/windows/uwp/porting/apps-on... > You can also select multi-core settings, as shown here... These settings change the number of memory barriers used to synchronize memory accesses between cores in apps during emulation. Fast is the default mode, but the strict and very strict options will increase the number of barriers. This slows down the app, but reduces the risk of app errors. The single-core option removes all barriers but forces all app threads to run on a single core. https://news.ycombinator.com/item?id=28732273 zamadatix's interprets this as Microsoft saying that by default, Windows on ARM runs x86 apps without x86 TSO, and turns on extra memory barriers using per-app compatibility settings. But if an app needs TSO but isn't in Windows's database, it will crash or silently corrupt data. |
