How to update MXCSR automatically? #2006

Open wtdcode opened 2 months ago

Discussed in https://github.com/unicorn-engine/unicorn/discussions/1981

Originally posted by **ALanovaya** July 23, 2024 I am emulating code on x86 that contains instructions working with floating point numbers, but for some reason during emulation the mxcsr register is not updated in any way, although I specifically emulated examples (for example, division by zero), where mxcsr was definitely supposed to change, but this did not happen Why is that ?
