On ARM and ARM64 there's only one type of handler which is invoked in both cases.Ok, so if that handler is called on arm also for unwind phase then we should skip EXCEPTION_UNWINDING case also for arm builds.
This has to be #if !(defined(__x86_64__) && !defined(__arm64ec__)) /* not physical x86-64 */ ARM64EC is similar to ARM64 as seen in https://github.com/lhmouse/arm64ec-playground/actions/runs/26689474508/job/78663245318#step:3 -- Best regards, LIU Hao
