2017-10-27	Merge PR #6015: [general] Remove Econstr dependency from `intf`	Maxime Dénès

2017-10-26	Passing around the flag for injection so that tactics calling inj at	Hugo Herbelin
	ML level can set the flags themselves. In particular, using injection and discriminate with option "Keep Proofs Equalities" when called from "decide equality" and "Scheme Equality". This fixes bug #5281.
2017-10-26	Delay use of flag "Discriminate Introduction" from interp to execution time.	Hugo Herbelin

2017-10-25	[general] Remove Econstr dependency from `intf`	Emilio Jesus Gallego Arias
	To this extent we factor out the relevant bits to a new file, ltac_pretype.
2017-10-19	Moving bug numbers to BZ# format in the source code.	Théo Zimmermann
	Compared to the original proposition (01f848d in #960), this commit only changes files containing bug numbers that are also PR numbers.

2017-09-28	Efficient fresh name generation relying on sets.	Pierre-Marie Pédrot
	The old algorithm was relying on list membership, which is O(n). This was nefarious for terms with many binders. We use instead sets in O(log n).
2017-09-26	Merge PR #688: Binding universe constraints in Definition/Inductive/etc...	Maxime Dénès

2017-09-25	Merge PR #1060: An optimization of tactic constructor	Maxime Dénès

2017-09-21	Mark "Set Tactic Compat Context" as deprecated.	Guillaume Melquiond
	It was introduced in 8.5 for compatibility with a 8.4 bug.
2017-09-19	An optimization of tactic constructor.	Hugo Herbelin
	As was questioned on Stack Overflow and discussed on Gitter, reduction of the conclusion of the goal was done up to n+1 times for a failing call to "constructor" on an inductive type of n constructors. We do it at most once. Reworking the layout of the code at the same time.
2017-09-19	Fixing bug #5741 (anomaly in info_trivial).	Hugo Herbelin
	The bug was introduced in 1559f73.

2017-09-19	Don't lose names in UState.universe_context.	Gaëtan Gilbert
	We dont care about the order of the binder map ([map] in the code) so no need to do tricky things with it.
2017-09-15	Merge PR #1046: Better error messages, fix for BZ#5723	Maxime Dénès

2017-09-15	Merge PR #1037: Parse directly to Sorts.family when appropriate.	Maxime Dénès

2017-09-15	Merge PR #1002: Partial fix of BZ#5707 ("destruct" on primitive "negative" ↵	Maxime Dénès
	Inductive-keyworded record failing even on non-dependent goal)
2017-09-14	Avoid extra failure in the "constructor" tactic (bug #5666).	Guillaume Melquiond
	This changes the implementation of "constructor" from constructor 1 + ... + constructor n + fail to constructor 1 + ... + constructor n.
2017-09-11	Better error messages, fix for BZ#5723	Paul Steckler

2017-09-08	Parse directly to Sorts.family when appropriate.	Gaëtan Gilbert
	When we used to parse to a glob_sort but always give an empty list in the GType case we can now parse directly to Sorts.family.
2017-09-04	Making detyping potentially lazy.	Pierre-Marie Pédrot
	The internal detype function takes an additional arguments dictating whether it should be eager or lazy. We introduce a new type of delayed `DAst.t` AST nodes and use it for `glob_constr`. Such type, instead of only containing a value, it can contain a lazy computation too. We use a GADT to discriminate between both uses statically, so that no delayed terms ever happen to be marshalled (which would raise anomalies). We also fix a regression in the test-suite: Mixing laziness and effects is a well-known hell. Here, an exception that was raised for mere control purpose was delayed and raised at a later time as an anomaly. We make the offending function eager.
2017-08-30	Fixing part of #5707 (allowing destruct to use non dependent case analysis).	Hugo Herbelin
	The fix covers the case of a non-dependent goal with unavailable dependent case analysis: destruct was not seeing that it could still use non-dependent case analysis.
2017-08-29	Fix BZ#5697: Congruence does not work with primitive projections.	Pierre-Marie Pédrot
	The code generating the projection was unconditionally generating pattern-matchings, although this is incorrect for primitive records.

2017-07-26	More precise type for universe entries.	Pierre-Marie Pédrot
	We use an algebraic type instead of a pair of a boolean and the corresponding data. For now, this is isomorphic, but this allows later change in the structure.

2017-07-19	[general] Move files to directories matching linking order.	Emilio Jesus Gallego Arias
	We move a bunch of modules (`Impargs`, `Declare`, `Ind_tables`, `Miscprint`) to their proper place as they were declared in different `mllib` files than the one in their directory. In some cases this could be refined but we don't do anything fancy, we just reflect the status quo.
2017-07-19	Fix debug trace of typeclasses eauto.	Théo Zimmermann

2017-07-18	Improve do_split option of typeclass resolution	Matthieu Sozeau
	It used to compute the dependencies of all undefined evars of the evar_map, while only the dependencies of resolvable evars are necessary.
2017-07-14	Getting rid of abstraction breaking code in tclABSTRACT.	Pierre-Marie Pédrot
	This is probably the hardest case of them all, because tclABSTRACT fundamentally relies on the names of universes from the constant instance being the same as the one in the current goal. Adding to that the fact that the kernel is doing strange things when provided with a polymorphic definition with body universe constraints, it turns out to be a hellish nightmare to handle properly. At some point we need to clarifiy this in the kernel as well, although we leave it for some other patch.
