      Invariants over states in WP and get rid of heap_ctx. · fd89aa52
      Robbert Krebbers authored
      The WP construction now takes an invariant on states as a parameter
      (part of the irisG class) and no longer builds in the authoritative
      ownership of the entire state. When instantiating WP with a concrete
      language on can choose its state invariant. For example, for heap_lang
      we directly use `auth (gmap loc (frac * dec_agree val))`, and avoid
      the indirection through invariants entirely.
      
      As a result, we no longer have to carry `heap_ctx` around.

      Use symbol ∗ for separating conjunction. · cc31476d
      Robbert Krebbers authored
      The old choice for ★ was a arbitrary: the precedence of the ASCII asterisk *
      was fixed at a wrong level in Coq, so we had to pick another symbol. The ★ was
      a random choice from a unicode chart.
      
      The new symbol ∗ (as proposed by David Swasey) corresponds better to
      conventional practise and matches the symbol we use on paper.

      Generalize update tactics into iMod and iModIntro for modalities. · fc30ca08
      Robbert Krebbers authored
      There are now two proof mode tactics for dealing with modalities:
      
      - `iModIntro` : introduction of a modality
      - `iMod pm_trm as (x1 ... xn) "ipat"` : eliminate a modality
      
      The behavior of these tactics can be controlled by instances of the `IntroModal`
      and `ElimModal` type class. We have declared instances for later, except 0,
      basic updates and fancy updates. The tactic `iMod` is flexible enough that it
      can also eliminate an updates around a weakest pre, and so forth.
      
      The corresponding introduction patterns of these tactics are `!>` and `>`.
      
      These tactics replace the tactics `iUpdIntro`, `iUpd` and `iTimeless`.
      
      Source of backwards incompatability: the introduction pattern `!>` is used for
      introduction of arbitrary modalities. It used to introduce laters by stripping
      of a later of each hypotheses.

      Rename rvs -> bupd (basic update), pvs -> fupd (fancy update). · 1b85d654

      And also rename the corresponding proof mode tactics.
