132 * The behavior this check tries to achieve is that if ExecMacro is on,
133 * the macroop will be printed. If it's on and microops are also on, it's
134 * printed before the microops start printing to give context. If the
135 * microops aren't printed, then it's printed only when the final microop
136 * finishes. Macroops then behave like regular instructions and don't
137 * complete/print when they fault.
