Some upcoming chips are supposed to support switching individual processes to x86's "TSO" memory model. That might be the most significant extension that Apple has for x86 emulation: it allows eliding all memory fence instructions used to adapt to the weaker memory model.
LoongArch could have instructions that emulate specific x86 behaviour and flags, but there is practically no documentation available.
