Removing unused argument and fixing bug #3899, now warning when a record
cannot be made primitive in Set Primitive Projections mode because it
has no projection or at least one undefinable projection.
|
|
Before the union was performed as a UContext.t union, that
concatenates the instances arrays, while one wants to avoid
duplicates.
We also assert that polymorphic constants have all constraints
in the constant_body (field const_universes), since the extra body
univs (stored in the opaque tables) are just for regular constants
processed asynchronously.

Such printer is already in Termops
This reverts commit 5d6106a075b79abbb92b03bbca7b13a517cf4925.

I find it very odd not to have a pretty printer for terms than can
be called from *everywhere*. This commit sticks in Term a long spaghetti
to let Printer install a printing function.

Fixes #3379 and part of #3363. Also avoids fragile code propagating required
libraries when closing an interactive module.
Had to fix a few occurrences in std lib.

We use private types to ensure apriori hashconsing, and get rid of the
use of recursive modules. The hash of the universe list is also inlined
into each node instead of relying on a supplementary indirection.

resulting in huge speedup at Qed/section closing in presence of
primitive projections.

Instead of modifying exceptions to wear additional information, we instead use
a dedicated type now. All exception-using functions were modified to support
this new type, in particular Future's fix_exn-s and the tactic monad.
To solve the problem of enriching exceptions at raise time and recover this
data in the try-with handler, we use a global datastructure recording the
given piece of data imperatively that we retrieve in the try-with handler.
We ensure that such instrumented try-with destroy the data so that there
may not be confusion with another exception. To further harden the correction
of this structure, we also check for pointer equality with the last raised
exception.
The global data structure is not thread-safe for now, which is incorrect as
the STM uses threads and enriched exceptions. Yet, we splitted the patch in
two parts, so that we do not introduce dependencies to the Thread library
immediatly. This will allow to revert only the second patch if ever we
switch to OCaml-coded lightweight threads.

Patch by CJ on bugzilla. CUnix.sys_command doesn't rely on a shell, so extra
care with cmd.exe vs sh is no longer required.

inductive types (i.e., ones declared with an explicit anonymous Type
at the conclusion of their arity). With this change one can force
inductives to live in higher universes even in the non-fully universe
polymorphic case (e.g. bug #3821).

This bug was affecting the VM and the native compiler, but only in the pretyper
(not the kernel). Types of arguments of fixpoints were incorrectly normalized
due to a missing lift.

inductive types + deactivate test for equality of sort + deactivate

Stop sharing those references across constants of the same
module, which was triggering some bugs when using native_compute
in interactive mode in a functor declaration.

I'm afraid this fix is a bit heuristic, but it seems to generate correct code in
all cases.

but the internal representation dropped let-in.
Ideally, the internal representation of the "match" should use
contexts for the predicate and the branches. This would however be a
rather significant change. In the meantime, just a hack.
To do, there is still an extra @ in the constructor name that does not
need to be there.

This makes CatsInZFC explode by expanding constants unnecessarily.
This reverts commit cf36105854c9a42960ee4139c6afdaa75ec8f31a.

This generalizes the BuildVi flag and lets one choose which
opaque proofs are done and which not.
|
|
Now the seff contains it directly, no need to force the future
or to hope that it is a Direct opaque proof.

Before this patch opaque tables were only growing, making them unusable
in interactive mode (leak on Undo).
With this patch the opaque tables are functional and part of the env.
I.e. a constant_body can point to the proof term in 2 ways:
1) directly (before the constant is discharged)
2) indirectly, via an int, that is mapped by the opaque table to
the proof term.
This is now consistent in batch/interactive mode
This is step 0 to make an interactive coqtop able to dump a .vo/.vi

for the record binder of classes. This name is no longer generated
in the kernel but part of the declaration. Also cleanup the interface
to recognize primitive records based on an option type instead of a
dynamic check of the length of an array.

inductives).
The implementation constant should have the a universe instance
of the same length, we assume the universes are in the same order
and we check that the definition does not add any constraints
to the expected ones. This fixes bug #3670.

it closer to evarconv/unification's behavior and it is less prone
to weird failures and successes in case of first-order unification
sending problems where the two terms have different types.

so as to reproduce correctly the reduction behavior of existing
projections, i.e. delta + iota. Make [projection] an abstract datatype
in Names.ml, most of the patch is about using that abstraction.
Fix unification.ml which tried canonical projections too early in
presence of primitive projections.

It is a fairly straightforward change but a tad tedious, I may have introduced some bugs in the process.
