2018-02-15coq_makefile: Support "" as the prefix in _CoqProjectJoachim Breitner
This fixes #6350 (and even comes with a test case). Refering to other directories as `-R … ""` is maybe not best practice, but some people out there do it, so as long as it does not cause too much trouble, we can continue to support it.

2018-02-12Fix #6677: Critical bug with VM and universesMaxime Dénès
This bug was present since the first patch adding universe polymorphism handling in the VM (Coq 8.5). Note that unsoundness can probably be observed even without universe polymorphism.

This ensures by construction that we never infer constraints outside the variance model.
2018-02-10Inference of inductive subtyping does not need an evar map.Gaëtan Gilbert
2018-02-10Simplification: cumulativity information is variance information.Gaëtan Gilbert
Since cumulativity of an inductive type is the universe constraints which make a term convertible with its universe-renamed copy, the only constraints we can get are between a universe and its copy. As such we do not need to be able to represent arbitrary constraints between universes and copied universes in a double-sized ucontext, instead we can just keep around an array describing whether a bound universe is covariant, invariant or irrelevant (CIC has no contravariant conversion rule). Printing is fairly obtuse and should be improved: when we print the CumulativityInfo we add marks to the universes of the instance: = for invariant, + for covariant and * for irrelevant. ie Record Foo@{i j k} := { foo : Type@{i} -> Type@{j} }. Print Foo. gives Cumulative Record Foo : Type@{max(i+1, j+1)} := Build_Foo { foo : Type@{i} -> Type@{j} } (* =i +j *k |= *)

2018-02-10Factorize code for comparing maybe-cumulative inductives.Gaëtan Gilbert
The part in Reduction should be semantics preserving, but Reductionops only tried cumulativity if equality fails. This is probably wrong so I changed it.

2018-02-09[nit] Remove some unnecessary global `open Feedback`Emilio Jesus Gallego Arias
2018-02-09[vernac] [minor] Move print effects to top-level caller.Emilio Jesus Gallego Arias
We remove many individual calls to `msg_notice` in the print vernacular dispatcher in favor of a single, top-level calls. This is a minor refactoring but will help in handling `Print Foo` more uniformly.
2018-02-09[error] Replace msg_error by a proper exception.Emilio Jesus Gallego Arias
The current error mechanism in the core part of Coq is 100% exception based; there was some confusion in the past as to whether raising and exception could be replace with `Feedback.msg_error`. As of today, this is not the case [due to some issues in the layer that generates error feedbacks in the STM] so all cases of `msg_error` must raise an exception of print at a different level [for now].
2018-02-09[nativecomp] Remove ad-hoc handling of Dynlink exception.Emilio Jesus Gallego Arias
Instead, we properly register a printer for such exception and update the code.
