AMX architecture involves several entities such as xstate, XCR0, IA32_XFD. This series add several missing checks on top of the existing amx_test.
v1 -> v2: - Add a working xstate data structure suggested by seanjc. - Split the checking of CR0.TS from the checking of XFD. - Fix all the issues pointed by in review.
