Changeset 9153:21a81cca6a86 --------------------------- x86: Add a separate register for D flag bit The D flag bit is part of the cc flag bit register currently. But since it is not being used any where in the implementation, it creates an unnecessary dependency. Hence, it is being moved to a separate register.

How do we handle system flags? I think DF is set rarely enough that we can probably lump it in with "everything else", though I think the rest of "everything else" is privileged (IF/TF/NT etc.).
