Beware of 0. = -0. issue for primitive floats
The IEEE 754 declares that 0. and -0. are treated equal but we cannot
say that this is true with Leibniz equality.
Therefore we must patch the equality and the total comparison inside the
kernel to prevent inconsistency.

We remove calls of `Lemmas.Info.make` that where using the default
parameters, as this is mostly dead code now.
This brings into question quite a few things, in particular, the
uneven support of `scope` attributes by different commands / plugins.
We don't attempt to solve that yet, hopefully the ongoing constant
saving path refactoring will be able to take care of these
inconsistencies.

We also attempt a version that may work with `Proofview.tactic` , may
need more work.

Not pretty, but it had to be done some day, as `Globnames` seems to be
on the way out.
I have taken the opportunity to reduce the number of `open` in the
codebase.
The qualified style would indeed allow us to use a bit nicer names
`GlobRef.Inductive` instead of `IndRef`, etc... once we have the
tooling to do large-scale refactoring that could be tried.

We remove the special error printing pre-processing in favor of just
calling the standard printers.
Error printing has been a bit complex for a while due to an incomplete
migration to a new printing scheme based on registering exception
printers; this PR should alleviate that by completing the registration
approach.
After this cleanup, it should not be ever necessary for normal
functions to worry a lot about catching errors and re-raising them,
unless they have some very special needs.
This change also allows to consolidate the `explainErr` and `himsg`
modules into one, removing the need to export the error printing
functions. Ideally we would make the contents of `himsg` more
localized, but this can be done in a gradual way.

We can use logical kind for the same purpose, which is mainly
dumpglob, so `goal_object_kind` was never matched against, making this
transformation safe.
|
|
We move the bulk of `Decl_kinds` to a better place [namely
`interp/decls`] and refactor the use of this information quite a bit.
The information seems to be used almost only for `Dumpglob`, so it
certainly should end there to achieve a cleaner core.
Note the previous commits, as well as the annotations regarding the
dubious use of the "variable" data managed by the `Decls` file.
IMO this needs more work, but this should be a good start.

We move special vernac-qed handling to a special function, making the
regular vernacular interpretation path uniform.
This is an important step as it paves the way up to export the vernac
DSL to clients, as there are no special vernacs anymore in the regular
interp path, except for Load, which should be handled separately due
to silly reasons, as morally it is a `VtNoProof` command.
|
|
This datatype does belong to this layer.
|
|
We split `{goal,declaration,assumption}_kind` into their
components. This makes sense as each part of this triple is handled by
a different layer, namely:
- `polymorphic` status: necessary for the lower engine layers;
- `locality`: only used in `vernac` top-level constants
- `kind`: merely used for cosmetic purposes [could indeed be removed /
pushed upwards]
We also profit from this refactoring to add some named parameters to
the top-level definition API which is quite parameter-hungry.
More refactoring is possible and will come in further commits, in
particular this is a step towards unifying the definition / lemma save path.
|
|
This information is already present on `Proof.t`, so we extract it
form there.
Moreover, this information is essential to the lower-level proof, as
opposed to the "kind" information which is only relevant to the vernac
layer; we will move it thus to its proper layer in subsequent commits.
|

Lemmas.info was a bit out of hand, as well as the parameters to the
`start_*` family. Most of the info is not needed and should hopefully
remain constrained to special cases, most callers only set the hook,
and obligations should be better served by a `start_obligation`
function soon.
|
|
We had to move the private opaque constraints out of the constant declaration
into the opaque table. The API is not very pretty yet due to a pervasive
confusion between monomorphic global constraints and polymorphic local ones,
but once we get rid of futures in the kernel this should be magically solved.
|
|

The main idea of this PR is to distinguish the types of "proof object"
`Proof_global.t` and the type of "proof object associated to a
constant, the new `Lemmas.t`.
This way, we can move the terminator setup to the higher layer in
`vernac`, which is the one that really knows about constants, paving
the way for further simplification and in particular for a unified
handling of constant saving by removal of the control inversion here.
Terminators are now internal to `Lemmas`, as it is the only part of
the code applying them.
As a consequence, proof nesting is now handled by `Lemmas`, and
`Proof_global.t` is just a single `Proof.t` plus some environmental
meta-data.
We are also enable considerable simplification in a future PR, as this
patch makes `Proof.t` and `Proof_global.t` essentially the same, so we
should expect to handle them under a unified interface.

Formerly, knowing if a declaration was to be discharged, to be global
but invisible at import, or to be global but visible at import was
obtained by combining the parser-level information (i.e. use of
Variable/Hypothesis/Let vs use of Axiom/Parameter/Definition/..., use
of Local vs Global) with the result of testing whether there were open
sections.
We change the meaning of the Discharge flag: it does not tell anymore
that it was syntactically a Variable/Hypothesis/Let, but tells the
expected semantics of the declaration (issuing a warning in the
parser-to-interpreter step if the semantics is not the one suggested
by the syntax). In particular, the interpretation/command engine
becomes independent of the parser.
The new "semantic" type is:
type import_status = ImportDefaultBehavior | ImportNeedQualified
type locality = Discharge | Global of import_status
In the process, we found a couple of inconsistencies in the treatment
of the locality status. See bug #8722 and test file LocalDefinition.v.

Typically instead of [start_proof : ontop:Proof_global.t option -> bla ->
Proof_global.t] we have [start_proof : bla -> Proof_global.pstate] and
the pstate is pushed on the stack by a caller around the
vernacentries/mlg level.
Naming can be a bit awkward, hopefully it can be improved (maybe in a
followup PR).
We can see some patterns appear waiting for nicer combinators, eg in
mlg we often only want to work with the current proof, not the stack.
Behaviour should be similar modulo bugs, let's see what CI says.
|

We simply pass them as arguments, now that they are not called by the
kernel anymore.
The checker definitely needs to access the opaque proofs. In order not to
touch the API at all, I added a hook there, but it could also be provided
as an additional argument, at the cost of changing all the upwards callers.
|
|
|
|
In that case the terminator and proof object have to be supplied in
the ?proof argument, or else we get an anomaly.

This should make https://github.com/coq/coq/pull/9129 easier.
|
|
Kernel should be mostly correct, higher levels do random stuff at
times.
|
|
Now the main functions are unify (solves the problems entirely) and
unify_delay and unify_leq (which might leave some unsolved constraints).
Deprecated the_conv_x and the_conv_x_leq (which were misnommers as they
do unification not conversion).

This work makes it possible to take advantage of a compact
representation for integers in the entire system, as opposed to only
in some reduction machines. It is useful for heavily computational
applications, where even constructing terms is not possible without such
a representation.
Concretely, it replaces part of the retroknowledge machinery with
a primitive construction for integers in terms, and introduces a kind of
FFI which maps constants to operators (on integers). Properties of these
operators are expressed as explicit axioms, whereas they were hidden in
the retroknowledge-based approach.
This has been presented at the Coq workshop and some Coq Working Groups,
and has been used by various groups for STM trace checking,
computational analysis, etc.

We make `declaration_hook`s optional arguments everywhere, and thus we
avoid some "fake" functions having to be passed.
This identifies positively the code really using hooks [funind,
rewrite, coercions, program, and canonicals] and helps moving toward
some hope of reification.
|
|
We remove the `Proof_types` file which was a trivial stub, we also
cleanup a few layers of aliases.
This is not a lot but every little step helps.

Funind doesn't support polymorphism.
|

We also stop passing dummy env and evar maps.

In favor of a constr_of_monomorphic_global function. When people
move to the new Coqlib interface they will also see this deprecation
message encouraging them to think about the best move.
This commit changes a few references to constr_of_global and replaces
them with a constr_of_monomorphic_global which makes it apparent that
this is not the function to call to globalize polymorphic references.
The remaining parts using constr_of_monomorphic_global are easily
identifiable using this: omega, btauto, ring, funind and auto_ind_decl
mainly (this fixes firstorder). What this means is that the symbols
registered for these tactics have to be monomorphic for now.

Lintian found some spelling errors in the Debian packaging for coq. Fix
them most places they appear in the current source. (Don't change
documentation anchor names, as that would invalidate external
deeplinks.)
This also fixes a bug in coqdoc: prior to this commit, coqdoc would
highlight `instanciate` but not `instantiate`.

We refactor the `Coqlib` API to locate objects over a namespace
`module.object.property`.
This introduces the vernacular command `Register g as n` to expose the
Coq constant `g` under the name `n` (through the `register_ref`
function). The constant can then be dynamically located using the
`lib_ref` function.

In locally nameless mode (proof mode) names in the context *must*
be distinct otherwise the term representation makes no sense.
|
|
We address the easy ones, but they should probably be all removed.
|
|
We remove the `fix N / cofix N` forms from the tactic language. This
way, these tactics don't depend anymore on the proof context, in
particular on the proof name, which seems like a fragile practice.
Apart from the concerns wrt maintenability of proof scripts, this also
helps making the "proof state" functional; as we don't have to
propagate the proof name to the tactic layer.

`Proof_global` is the main consumer of the flag, which doesn't seem to
belong to the AST as plugins show.
This will allow the vernac AST to be placed in `vernac` indeed.

We bootstrap the circular evar_map <-> econstr dependency by moving
the internal EConstr.API module to Evd.MiniEConstr. Then we make the
Evd functions use econstr.
|
|
|
|
We mirror the structure of EConstr and move the destructors from `Term`
to `Constr`.
This is a step towards having a single module for `Constr`.
|
|
We'd like to handle proofs functionally we thus recommend not to use
printing functions without an explicit context.
We also adapt most of the code, making more explicit where the
printing environment is coming from.
An open task is to refactor some code so we gradually make the
`Pfedit.get_current_context ()` disappear.

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).
