2015-12-09bug fixes to vm computation + test cases.Gregory Malecha
2015-12-07Fix some typos.Guillaume Melquiond
2015-12-05Changing "destruct !hyp" into "destruct (hyp)" (and similarly for induction)Hugo Herbelin
based on a suggestion of Guillaume M. (done like this in ssreflect). This is actually consistent with the hack of using "destruct (1)" to mean the term 1 by opposition to the use of "destruct 1" to mean the first non-dependent hypothesis of the goal.
2015-12-03Univs: fix bug #4443.Matthieu Sozeau
Do not substitute rigid variables during minimization, keeping their equality constraints instead.
2015-12-02Adding a target report to test-suite's Makefile to get a short summary.Hugo Herbelin
2015-12-02Improving syntax of pat/constr introduction pattern so thatHugo Herbelin
pat/c1/.../cn behaves as intro H; apply c1, ... , cn in H as pat. Open to other suggestions of syntax though.

2015-11-27Univs: entirely disallow instantiation of polymorphic constants withMatthieu Sozeau
Prop levels. As they are typed assuming all variables are >= Set now, and this was breaking an invariant in typing. Only one instance in the standard library was used in Hurkens, which can be avoided easily. This also avoids displaying unnecessary >= Set constraints everywhere.
2015-11-26Fixing the "parsing rules with idents later declared as keywords" problem.Hugo Herbelin
The fix was actually elementary. The lexer comes with a function to compare parsed tokens against tokens of the parsing rules. It is enough to have this function considering an ident in a parsing rule to be equal to the corresponding string parsed as a keyword.
2015-11-22Fixing a vm_compute bug in the presence of let-ins among theHugo Herbelin
parameters of an inductive type.
2015-11-22Fixing a bug of adjust_subst_to_rel_context.Hugo Herbelin
2015-11-22Fixing kernel bug in typing match with let-ins in the arity.Hugo Herbelin
Was exploitable in 8.3, 8.4 and 8.5beta1. A priori not exploitable in 8.5beta2 and 8.5beta3 from a Coq file because typing done while compiling "match" would serve as a protection. However exploitable by calling the kernel directly, e.g. from a plugin (but a plugin can anyway do what it wants by bypassing kernel type abstraction). Fixing similar error in pretyping.
2015-11-19Fix bug #4429: eauto with arith: 70x performance regression in Coq 8.5.Pierre-Marie Pédrot
The issue was due to the fact that unfold hints are given a priority of 4 by default. As eauto was now using hint priority rather than the number of goals produced to order the application of hints, unfold were almost always used too late. We fixed this by manually giving them a priority of 1 in the eauto tactic. Also fixed the relative order of proof depth w.r.t. hint priority. It should not be observable except for breadth-first search, which is seldom used.

projections. - lift accounting for the record missing in computing the subst from fields to projections of the record - substitution for parameters should not lift the local definitions - typo in building the latter (subst -> letsubst)
2015-11-12Fix bug #4412: [rewrite] (setoid_rewrite?) creates ill-typed terms.Pierre-Marie Pédrot
We retypecheck the hypotheses introduced by the refine primitive instead of blindly trusting them when the unsafe flag is set to false.

2015-11-11Fixing bug #3554: Anomaly: Anonymous implicit argument.Pierre-Marie Pédrot
We just handle unnamed implicits using a dummy name. Note that the implicit argument logic should still output warnings whenever the user writes implicit arguments that won't be taken into account, but I'll leave that for another time.

2015-11-06Fixing complexity issue with f_equal. Thanks to J.-H. JourdanHugo Herbelin
for reporting it. A "cut" was not appropriately chained on the second goal but on both goals, with the chaining on the first goal introducing noise.

2015-10-24Backtracking on interpreting toplevel calls to exact in scope determinedHugo Herbelin
by the type to prove (was introduced in 35846ec22, r15978, Nov 2012). Not only it does not work when exact is called via a Ltac definition, but, also, it does not scale easily to refine which is a TACTIC EXTEND. Ideally, one may then want to propagate scope interpretations through ltac variables, as well as supporting refine... See #4034 for a discussion.
