750a491 [build]: use camlp-streams This resolves the deprecation warning about the Stream module. Fix #186 05 September 2022, 08:46:47 UTC
70ac960 [breaking] Fix unsound pHL while rule This fixes #212 and implements a version of the pHL while rule which does have a(n unpublished) pen-and-paper proof. This (obviously) makes using the pHL while rule generally less simple, but particularly so when the loop condition itself is probabilistically modified by the loop body (as, for example, in rejection sampling). In general, the bound given to the `while` tactic in those cases will need to be conditional. (Essentially capturing control-flow conditions in the bound itself.) Examples of proofs illustrating this case can be found in theories/distributions/Dexcepted.ec (starting line 299, including the conseq) and examples/PIR.ec (starting line 202, including also the conseq). Upper-bounds should be unaffected. On lower bounds, one can no longer apply the upper bound rule. On equalities, we have now added the lower-bound exit check (that if the loop is not entered and the event is true, then the probability should be 1), and further missing checks. In all cases, the inductive reasoning case was simplified to remove duplicated control-flow. co-authored-by: Benjamin Grégoire <benjamin.gregoire@inria.fr> co-authored-by: François Dupressoir <fdupress@gmail.com> 05 September 2022, 08:27:00 UTC

b2273f0 Add a warning for useless delta-unfolding The option name is `und_delta`. It is disabled by default. The mechanism can emit false positive, e.g. in: `try rewrite /foo.` 29 August 2022, 13:02:25 UTC
f9d2bf6 When replaying a reduction rule, check that the rule does still exists. Currently, when the reduction rule does not exist anymore (because it has been removed by the inlining mechanism), the cloning fails with a lookup error. Ref #247 23 August 2022, 16:00:41 UTC

5524b72 Fix ordering of variables in `rndsem` The chosen ordering is the order of appearance as a left-value in the program. fix #220 09 July 2022, 06:08:59 UTC
ca3d10a Fix naming issue for the [#] intro-pattern When having a conclusion of the form "forall x, E[x]", the intro-pattern [#] was renaming `x` as `_`. Internal: low-level intro tactic that returns the generated intro name fix #221 09 July 2022, 05:29:53 UTC

9d00961 Extend `rnd` tactic s.t. it can handle multiple samplings / assignments Syntax is `rnd ... : pos1 pos2` and is only evailable for the pRHL variant. The tactic will first collapse all the instructions after `pos1` / `pos2` (in the left/right programs) before applying the `rnd` tactic. It is also possible to access this collapse phase with the new `rndsem` tactic. The syntax is: `rndsem side? codepos` 29 June 2022, 14:12:18 UTC
f6ca7bf remove "rnd := f" syntax 29 June 2022, 14:12:18 UTC
dafa224 Switched from x <> y being expanded by the parser to ! (x = y), and consequently having several explicit parsing rules (including one involving using it as a constructor in a match, which was buggy) to removing the special parsing treatment and adding it as an abbreviation. fixes #217 28 June 2022, 17:03:43 UTC
cec6716 In loop fusion/fission, add more constraints on the epilog Loops' epilogs must now be deterministic and loop/calls-free. This forbids the following unsoundness: ``` require import AllCore DBool. module E = { var i,j : int proc foo () = { var c; i <- 0; j <- 0; c <- false; while (!c) { i <- i + 1; j <- j + 1; c <$ {0,1}; } return i = j; } proc bar () = { var c; i <- 0; j <- 0; c <- false; while (!c) { i <- i + 1; c <$ {0,1}; } c <- false; while (!c) { j <- j + 1; c <$ {0,1}; } return i = j; } }. equiv bad : E.foo ~ E.bar : true ==> ={res}. proof. proc. fission{1} 4!1 @1,2. by sim. qed. ``` Fix #210 11 June 2022, 06:10:21 UTC

5d030a1 Enforce separation between <- and <@ more strictly This removes the error message when the RHS is a procedure call. This allows us to accept things that were rejected before, when a procedure and operator share their name. A follow-up may re-enable it. Fix #189 12 May 2022, 06:49:18 UTC
