Last change on this file since 94249 was 93901, checked in by vboxsync, 3 years ago

VMM,Main,++: Removed VM_IS_RAW_MODE_ENABLED/VM_EXEC_ENGINE_RAW_MODE and added VM_IS_EXEC_ENGINE_IEM/VM_EXEC_ENGINE_IEM instead. In IMachineDebugger::getExecutionEngine VMExecutionEngine_RawMode was removed and VMExecutionEngine_Emulated added. Removed dead code and updated frontends accordingly. On darwin.arm64 HM now falls back on IEM execution since neither HM or NEM is availble there. bugref:9898
