Gerwin Klein c6564cb4cb infoflow: 2015 update for infoflow C refinement 2015-05-20 21:10:59 +10:00
Gerwin Klein 29eb636d31 re-establish InfoFlow; generalising ptable_xn 
UserOp_IF had its own way of extracting the XN bit from page tables.
This is now unified with the existing functions in ADT_AI, which also
means that the proof for XN bit equality is basically the same as for
pt_rights and pt_lift.

deang 6df2eb6cf9 infoflow: weakened assumptions for c refinement of infoflow adts 
The fact that the C infoflow adt refines the abstract infoflow adt now only requires that given user operation is nonempty and not sane (nonempty and doesn't return an interrupt).
Also added some more general lemmas about fw_sim and refinement to lib/Simulation.thy.
