The logical clause and the pre-state are now optional. The function can now
be used to remove from a state all inferred properties that depend on a given
memory location.
This only impacts the cvalue domain, which is the only one to use the assign
clause.

Queries return an origin option instead of an origin.
Domains not using the origin simply return None, and no longer need to define
the origin type.

[Eva] very imprecise (but fast) builtin for memory allocation

See merge request frama-c/frama-c!2309

Uses [memo] from State_builder.Option_ref.
Also stores the maximum size of the allocated bases once for all, instead of
calling [Bit_utils.max_bit_adddress] in various places.

Resolve "[wp] missing opening scope on goto"

Closes #837

[Eva] Fixes the user manuel: Eva warns on indeterminate copies by default.

See merge request frama-c/frama-c!2615

Since 2016…

In the user manual and in the man page.

[eacsl:doc] Misc doc fixes

See merge request frama-c/frama-c!2597

- Function contracts: remove abrupt clauses from the list of exceptions
- Statement contracts: remove abrupt clauses from the list of exceptions
- Add grammar for abrupt termination
- Update list of contributors

[Userman] add diagram about source preparation

Closes #802

[debug] more robust bin/frama-c.debug script across OCaml versions

See merge request frama-c/frama-c!2612

- 4.08.0 messes up dynlink, which is needed by extlib for semi-good reasons:
  it is currently impossible to load the printers in this version.
- 4.09.0 and upwards directly load dynlink, and will complain if we try to
  do that again.

[cmdline] Fixes multiple_map parameters when a key is not bound to a value.

See merge request frama-c/frama-c!2584

David Bühler authored Apr 01, 2020 and Julien Signoles committed Apr 01, 2020

For a Multiple_map paramater for an option "-option", build by the functor
`Make_multiple_map (Key) (V)`:
when a command line contains a key without a value ("-option key" instead of
"-option key:v"), calls the function [V.of_string key None].

[Eva] Relaxes the check of builtin types for void pointers.

See merge request frama-c/frama-c!2610

[Kernel] Synchronization between logic and C vars representing a C function

Closes #840

See merge request frama-c/frama-c!2609

When a builtin expects a void pointer (as argument or result), any pointer type
is accepted.
This allows allocation builtins to be used for more functions.
