Could you update the comment?

It's a bit less clear now how the InstX8632 and OperandX8632 classes are
declared now that the file is mostly empty.

[John, 2015/07/06 22:30:09]

Done.

 // their subclasses.  This represents the machine instructions and
 // operands used for x86-32 code selection.

-//     cmp a, b

-//     FakeUse(c)
-//   L1:
-//     mov c, y
-//   L2:
-//
-// The down-side is that "mov c, x" can never be dead-code eliminated
-// even if there are no uses of c.  As unlikely as this situation is,
-// it may be prevented by running dead code elimination before
-// lowering.
