Fix typos in operational semantics for "Loop" command

509ebb1d06 Fix typo in ConcurrentSeparationLogic.v example 
In the 3-stage example, the middle stage moves list elements from the
first stack to the second stack, not back onto the first stack again.

bd92c1cbb3 Fix typos in operational semantics for "Loop" command 
In section 13.3, the type of Loop is defined as:

    Loop : forall a, a -> (a -> cmd (outcome a)) -> cmd a

However, the operational semantics provided in sections 14.1 and 18.1
invoke the loop body function using "Again(i)" (type "outcome a").
They should instead use simply "i" (type "a").

Changing to "f(i)" also matches the StepLoop formalizations in
SeparationLogic.v and ConcurrentSeparationLogic.v, which invoke simply
"body init" (rather than "body (Again init)").

Merge pull request #48 from mdempsky/sepcancel-typo 
Add missing parentheses in SepCancel's normalize2 tactic
 2020-07-25 09:18:19 -04:00

0a55c03aa0 Add missing parentheses in SepCancel's normalize2 tactic 
Before this change, "Print normalize2" prints:

    Ltac Frap.SepCancel.Make.normalize2 :=
      match goal with
      | |- context [ (?p * lift) (?P /\ ?Q) ] => rewrite (lift_uncombine p P Q)
      | |- context [ ?p * (?q * ?r) ] => rewrite (star_assoc p q r)
      end

After, it prints:

    Ltac Frap.SepCancel.Make.normalize2 :=
      match goal with
      | |- context [ ?p * [|?P /\ ?Q|] ] => rewrite (lift_uncombine p P Q)
      | |- context [ ?p * (?q * ?r) ] => rewrite (star_assoc p q r)
      end
