Microsoft's translator (and QEMU?) does insert extra barriers to make it run on a weak memory model, because they are designed to run on HW without TSO.
Note: writing an x86 emulator on ARM forces you to deal with this in a particularly messy way because you never know when reordering will be a problem so you typically have to insert a lot of memory barriers. Or you can follow Apple’s strategy and add a CPU mode that enforces x86/x64 memory ordering, turning that on when emulating.
What is surprising with Apple is that they were allowed to add extra instructions for machine learning related math (yeah, CPU instructions in addition to a dedicated separate "neural engine" on the chip: https://news.ycombinator.com/item?id=24471699)
However, Apple is one of the founding ARM partners and it is rumored they have a special license (not all licenses are created equal). Clearly they are doing this mode thing. Whether Samsung could get away with the exact same thing is a good question. I'm going to guess that NVidia can.
