2018-02-12[engine] Remove ghost parameter from `Proofview.Goal.t`Emilio Jesus Gallego Arias
In current code, `Proofview.Goal.t` uses a phantom type to indicate whether the goal was properly substituted wrt current `evar_map` or not. After the introduction of `EConstr`, this distinction should have become unnecessary, thus we remove the phantom parameter from `'a Proofview.Goal.t`. This may introduce some minor incompatibilities at the typing level. Code-wise, things should remain the same. We thus deprecate `assume`. In a next commit, we will remove normalization as much as possible from the code.
2018-02-12Add notation {x & P} for sigTTej Chajed
Analogous to existing `{x | P}` notation for `sig`, where the type of `x` is inferred instead of specified.

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.

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 |= *)

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[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[toplevel] Refactor command line argument handling.Emilio Jesus Gallego Arias
We mostly separate command line argument parsing from interpretation, some (minor) imperative actions are still done at argument parsing time. This tidies up the code quite a bit and allows to better follow the complicated command line handling code. To this effect, we group the key actions to be performed by the toplevel into a new record type. There is still room to improve.

2018-02-08Auto-create .git/hooks/pre-commit on ./configureJason Gross
The hook created checks to see if dev/tools/pre-commit exists, and, if so, runs it. This way, we don't have to do any fancy logic to update the git pre-commit hook. The configure script never overwrites an existing precommit hook, so users can disable it by creating an empty pre-commit hook. The check for existence is so that if users check out an old version of Coq, attempting to commit won't give an error about non-existent files.
