      Remove the `default` notation for options · e585be6d
      Ralf Jung authored
      The notation was parsing-only and all it did was reorder the arguments for
      from_option.  This creates just a needless divergence between what is written
      and what is printed.  Also, removing it frees the name for maybe introducing a
      function or notation `default` with a type like `T -> option T -> T`.

      Make `fmap` left associative. · 12e701ca
      Robbert Krebbers authored
      This follows the associativity in Haskell. So, something like
      
        f <$> g <$> h
      
      Is now parsed as:
      
        (f <$> g) <$> h
      
      Since the functor is a generalized form of function application, this also now
      also corresponds with the associativity of function application, which is also
      left associative.

      Port to Coq 8.5 beta 2. · 02f213ce
      Robbert Krebbers authored
      The port makes the following notable changes:
      
      * The carrier types of separation algebras and integer environments are no
        longer in Set. Now they have a type at a fixed type level above Set. This
        both works better in 8.5 and makes the formalization more general.
        I have tried putting them at polymorphic type levels, but that increased the
        compilation time by an order of magnitude.
      * I am using a custom f_equal tactic written in Ltac to circumvent bug #4069.
        That bug has been fixed, so this custom tactic can be removed when the next
        beta of 8.5 is out.

      Changes in preparation of the C type system and C front-end language · 3503a91f
      Robbert Krebbers authored
      Major changes:
      * Make void a base type, and include a proper void base value. This is necessary
        because expressions (free, functions without return value) can yield a void.
        We now also allow void casts conforming to the C standard.
      * Various missing lemmas about typing, weakening, decidability, ...
      * The operations "free" and "alloc" now operate on l-values instead of r-values.
        This removes some duplication.
      * Improve notations of expressions and statements. Change the presence of the
        operators conforming to the C standard.
      
      Small changes:
      * Use the classes "Typed" and "TypeCheck" for validity of indexes in memory.
        This gives more uniform notations.
      * New tactic "typed_inversion" performs inversion on an inductive predicate
        of type "Typed" and folds the premises.
      * Remove a horrible hack in the definitions of the classes "FMap", "MBind",
        "OMap", "Alter" that was used to let "simpl" behave better. Instead, we have
        defined a tactic "csimpl" that folds the results after performing an
        ordinary "simpl".
      * Fast operation to remove duplicates from lists using hashsets.
      * Make various type constructors (mainly finite map implementations) universe
        polymorphic by packing them into an inductive. This way, the whole C syntax
        can live in type, avoiding the need for (slow) universe checks.

      Preparation to port the master branch · d60affc0
      Robbert Krebbers authored
      Major changes:
      * A data structure to collect locked addresses in memory.
      * Operations to lock and unlock addresses.
      * Remove [ctree_Forall] and express it using [Forall] and [ctree_flatten]. This
        saves a lot of lines of code.
      * Add a [void] value. This value cannot be typed, but will be used as a dummy
        return value for functions with return type [void].
      
      Minor changes:
      * Various deciders in preparation of the executable semantics.
      * Improve naming and notations.
      * Remove obsolete stuff.
