+
+qemu, however, does restore this bit from `srr1`.
+
+Some ppcel operating systems rely on MSR_ILE not being restored by `rfi`, for example, Windows NT when taking a syscall."""

+
+The correct behaviour for G4 and prior is performed for later processors too. Given PPC970 and later have that bit documented as reserved, this should not be a problem."""
