We move Coqlib to library in preparation for the late binding of
Gallina-level references. Placing `Coqlib` in `library/` is convenient
as some components such as pretyping need to depend on it.
By moving we lose the ability to locate references by syntactic
abbreviations, but IMHO it makes to require ML code to refer to
a true constant instead of an abbreviation/notation.
Unfortunately this change means that we break the `Coqlib`
API (providing a compatibility function is not possible), however we
do so for a good reason.
The main changes are:
- move `Coqlib` to `library/`.
- remove reference -> term from `Coqlib`. In particular, clients will
have different needs with regards to universes/evar_maps, so we
force them to call the (not very safe) `Universes.constr_of_global`
explicitly so the users are marked.
- move late binding of impossible case from `Termops` to
`pretying/Evarconv`. Remove hook.
- `Coqlib.find_reference` doesn't support syntactic abbreviations
anymore.
- remove duplication of `Coqlib` code in `Program`.
- remove duplication of `Coqlib` code in `Ltac.Rewrite`.
- A special note about bug 5066 and commit 6e87877 . This case
illustrates the danger of duplication in the code base; the solution
chosen there was to transform the not-found anomaly into an error
message, however the general policy was far from clear. The long
term solution is indeed make `find_reference` emit `Not_found` and
let the client handle the error maybe non-fatally. (so they can test
for constants.

We remove redundant functions `coq_constant`, `gen_reference`, and
`gen_constant`.
This is a first step towards a lazy binding of libraries references.
We have also chosen to untangle `constr` from `Coqlib`, as how to
instantiate the reference (in particular wrt universes) is a
client-side issue. (The client may want to provide an `evar_map` ?)

Inspired by https://coq.inria.fr/bugs/show_bug.cgi?id=5229 , which
this PR solves, I propose to remove support for non-synchronous
options.
It seems the few uses of `optsync = false` we legacy and shouldn't
have any impact.
Moreover, non synchronous options may create particularly tricky
situations as for instance, they won't be propagated to workers.

This fixes an inconsistency introduced in 554a6c806 (svn r12603) where
both interp_constr_with_bindings and interp_open_constr_with_bindings
were going through interp_open_constr (no type classes so as to not to
commit too early on irreversible choices, accepting unresolved holes).
We fix this by having interp_constr_with_bindings going to
interp_constr (using type classes and failing on unresolved evars).
The external impact is that any TACTIC EXTEND which refers to
constr_with_binding has now to decide whether it intends it to use
what the name suggest (using type classes and to fail if evars remain
unresolved), thus keeping constr_with_binding, or the actual behavior
which requires to use open_constr_with_bindings for strict
compatibility.

We seized this opportunity to factorize the code for interning `pat
with more general pre-existing code.
More precisely: There was already a function to compute the free
variables of a pattern. Commit c6d9d4fb rewrote an approximation of it
and #5222 hits cases non-treated by this function. We remove the
partially-defined redundant code and use instead the existing code
since intern_cases_pattern, already called, was already doing this
computation. (In doing so, we discover a bug in merging names in the
presence of nested "as" clauses, which we fix in previous
commit. Additionally, intern_local_pattern was misleadingly overkill
to simply mean a folding on Id.Set.add and we avoid the detour.

1969e10f25df0c913600099b7b98ea273a064017 introduced a check so a cast
in a pattern is not a fatal error.
We move this check to the internalization function, which is the
logical place to raise it, removing a bit boilerplate code.

The type `raw_cases_pattern_expr` is used only in the interpretation
of notation patterns. Indeed, this should be a private type thus we
make it local to `Constrintern`; it makes no sense to expose it in the
public AST.
The patch is routine, except for the case used to interpret primitives
in patterns. We now return a `glob_constr` representing the raw
pattern, instead of the private raw pattern type. This could be
further refactored but have opted to be conservative here.
This patch is a refinement of b2953849b999d1c3b42c0f494b234f2a93ac7754
, see the commentaries there for more information about
`raw_cases_pattern_expr`.

This reverts commit 7bdfa1a4e46acf11d199a07bfca0bc59381874c3.

I'm sure this was pushed by accident, since testing shows immediately
that it breaks the compilation of the ssreflect plugin, hence all
developments relying on it in Travis.
|
|
A priori considered to be a good programming style.
|
|
This highlights that this is a binary mode changing the interpretation
of "?x" rather than additionally allowing patvar.

Following @gasche idea, and the original intention of #402, we switch
the main parsing AST of Coq from `'a Loc.located` to `'a CAst.ast`
which is private and record-based.
This provides significantly clearer code for the AST, and is robust
wrt attributes.
|
|
This completes the Loc.ghost removal, the idea is to gear the API
towards optional, but uniform, location handling.
We don't print <unknown> anymore in the case there is no location.
This is what the test suite expects.
The old printing logic for located items was a bit inconsistent as
it sometimes printed <unknown> and other times it printed nothing as
the caller checked for `is_ghost` upstream.
|
|
Now it is a private field, locations are optional.

We continue the uniformization pass. No big news here, trying to be
minimally invasive.

This is the second patch, which is a bit more invasive. We reasoning
is similar to the previous patch.
Code is not as clean as it could as we would need to convert
`glob_constr` to located too, then a few parts could just map the
location.
|
|
This is first of a series of patches, converting `constrexpr` pattern
data type from ad-hoc location handling to `Loc.located`.
Along Coq, we can find two different coding styles for handling
objects with location information: one style uses `'a Loc.located`,
whereas other data structures directly embed `Loc.t` in their
constructors.
Handling all located objects uniformly would be very convenient, and
would allow optimizing certain cases, in particular making located
smarter when there is no location information, as it is the case for
all terms coming from the kernel.
`git grep 'Loc.t \*'` gives an overview of the remaining work to do.
We've also added an experimental API for `located` to the `Loc`
module, `Loc.tag` should be used to add locations objects, making it
explicit in the code when a "located" object is created.

Binding generalizable_vars_of_glob_constr, occur_glob_constr,
free_glob_vars, and bound_glob_vars on it.
Most of the functions of which it factorizes the code were bugged with
respect to bindings in the return clause of "match" and in either the
types or the bodies of "fix/cofix".

record fields.

This allows e.g. to use the record notations even when there are
defined fields.
A priori fixed also missing parameters when interpreting primitive
tokens.
