We store bound variable names instead of functions for both branches and
predicate, and we furthermore add the parameters in the node. Let bindings
are not taken into account and require an environment lookup for retrieval.
|
|
They are not used there, and removing the redundance of the the case
representation requires access to the environment, so we push their use
further up.

Persistent arrays expose a functional interface but are implemented
using an imperative data structure. The OCaml implementation is based on
Jean-Christophe Filliâtre's.

This corresponds more naturally to the use we make of them, as we don't need
fast indexation but we instead keep pushing terms on top of them.
|
|
Add headers to a few files which were missing them.
|
|
Instead of various termops and globnames aliases.
|
|
We also remove trailing whitespace.
Script used:
```bash
for i in `find . -name '*.ml' -or -name '*.mli' -or -name '*.mlg'`; do expand -i "$i" | sponge "$i"; sed -e's/[[:space:]]*$//' -i.bak "$i"; done
```

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.

Kernel should be mostly correct, higher levels do random stuff at
times.

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.

This is to move a standard combinator to the place it belongs to. An
alternative could have been to put it in termops.ml, but termops.ml is
now about econstr, so, even if it makes the kernel "bigger", constr.ml
seems to be the best place for this combinator. After all, this
combinator is canonical.

A few of them will be of help for future cleanups. We have spared the
stuff in `Names` due to bad organization of this module following the
split from `Term`, which really difficult things removing the
constructors.

We build the `@doc` target in the `dune` job:
- The documentation can be found in `_build/default/_doc/`
- We had to fix a couple of quoting problems.
|
|
More precisely: the lambda-let-expanded canonical form of branches and
return predicate is considered as part of the structure of a "match"
and is preserved.
|
|
This shall eventually allow to use contexts of declarations in the
definition of the "Case" constructor.
Basically, this means that Constr now includes Context and that the
"t" types of Context which were specialized on constr are not defined
in Constr (unfortunately using a heavy boilerplate).
|
|
And similarly for fixpoint and cofixpoint.
|
|
Dependency analysis for separate compilation was not iterated properly
on rel_context and named_context.
|
|
In #6092, `global_reference` was moved to `kernel`. It makes sense to
go further and use the current kernel style for names.
This has a good effect on the dependency graph, as some core modules
don't depend on library anymore.
A question about providing equality for the GloRef module remains, as
there are two different notions of equality for constants. In that
sense, `KerPair` seems suspicious and at some point it should be
looked at.

Previously [fun x : Ind@{i} => x : Ind@{j}] with Ind some cumulative
inductive would try to generate a constraint [i = j] and use
cumulativity only if this resulted in an inconsistency. This is
confusingly different from the behaviour with [Type] and means
cumulativity can only be used to lift between universes related by
strict inequalities. (This isn't a kernel restriction so there might
be some workaround to send the kernel the right constraints, but
not in a nice way.)
See modified test for more details of what is now possible.
Technical notes:
When universe constraints were inferred by comparing the shape of
terms without reduction, cumulativity was not used and so too-strict
equality constraints were generated. Then in order to use cumulativity
we had to make this comparison fail to fall back to full conversion.
When unifiying 2 instances of a cumulative inductive type, if there
are any Irrelevant universes we try to unify them if they are
flexible.

We separate functions dealing with VM values (vmvalues.ml) and
interfaces of the bytecode interpreter (vm.ml). Only the former relies
on untyped constructions.
This also makes the VM architecture closer to the one of native_compute,
another patch could probably try to share more code between the two for
conversion and reification (not trivial, though).
This is also preliminary work for integers and arrays.

|
The comment had the type and value of the let-in swapped, which contradicted the listed types.
|
|
There don't really bring anything, we also correct some minor nits
with the printing function.
|
|
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 do up to `Term` which is the main bulk of the changes.
|
|
This will allow to merge back `Names` with `API.Names`
