      Fix issue #98. · e17ac4ad
      Robbert Krebbers authored
      We used to normalize the goal, and then checked whether it was of
      a certain shape. Since `uPred_valid P` normalized to `True ⊢ P`,
      there was no way of making a distinction between the two, hence
      `True ⊢ P` was treated as `uPred_valid P`.
      
      In this commit, I use type classes to check whether the goal is of
      a certain shape. Since we declared `uPred_valid` as `Typeclasses
      Opaque`, we can now make a distinction between `True ⊢ P` and
      `uPred_valid P`.

      Let stateful tactics try all decompositions. · 284ccdd5
      Robbert Krebbers authored
      This problem has been reported by Léon Gondelman.
      
      Before, when using, for example wp_alloc, in an expression like:
      
        ref (ref v)
      
      It would apply `tac_wp_alloc` to the outermost ref, after which it
      fails to establish that the argument `ref v` is a value. In this
      commit, other evaluation positions will be tried whenever it turn
      out that the argument of the construct is not a value. The same
      applies to store/cas/...
      
      I have implemented this by making use of the new `IntoVal` class.

      The `PureExec` typeclass for performing pure symbolic executions. · bbcd2c84
      Dan Frumin authored
      Instead of writing a separate tactic lemma for each pure reduction,
      there is a single tactic lemma for performing all of them.
      
      The instances of PureExec can be shared between WP tactics and, e.g.
      symbolic execution in the ghost  threadpool
