The bytecode interpreter ensures that the stack space available at some
points is above a static threshold. However, arbitrary large stack space
can be needed between two check points, leading to segmentation faults
in some cases.
We track the use of stack space at compilation time and add
an instruction to ensure greater stack capacity when required. This is
inspired from OCaml's PR#339 and PR#7168.
Patch written with Benjamin Grégoire.

The greatest danger of OCaml's polymorphic equality is that PMP can
replace it with pointer equality at any time, be warned :)
The lack of optimization may account for an exponential blow-up in size
of the generated code, as well as worse runtime performance.

This field was only used by the VM before, but since the previous patches,
this part of the code relies on the map instead.

This fixes #3450 and probably provides a huge speed-up to many instances.

In coqtop, one could do for instance:
Require Import Top. (* Where Top contains a Definition b := true *)
Lemma bE : b = true. Proof. reflexivity. Qed.
Definition b := false.
Lemma bad : False. Proof. generalize bE; compute; discriminate. Qed.
That proof could however not be saved because of the circular dependency check.
Safe_typing now checks that we are not requiring (Safe_typing.import) a library
with the same logical name as the current one.

Because refreshing Prop is not semantics-preserving,
the new universe is >= Set, so cannot be minimized to Prop
afterwards.

This is a reimplementation of Hugo's PR#117.
We are trying to address the problem that the name of some reduction functions
was not saying what they were doing (e.g. whd_betadeltaiota was doing let-in
reduction). Like PR#117, we are careful that no function changed semantics
without changing the names. Porting existing ML code should be a matter of
renamings a few function calls.
Also, we introduce more precise reduction flags fMATCH, fFIX, fCOFIX
collectively denominated iota.
We renamed the following functions:
Closure.betadeltaiota -> Closure.all
Closure.betadeltaiotanolet -> Closure.allnolet
Reductionops.beta -> Closure.beta
Reductionops.zeta -> Closure.zeta
Reductionops.betaiota -> Closure.betaiota
Reductionops.betaiotazeta -> Closure.betaiotazeta
Reductionops.delta -> Closure.delta
Reductionops.betalet -> Closure.betazeta
Reductionops.betadelta -> Closure.betadeltazeta
Reductionops.betadeltaiota -> Closure.all
Reductionops.betadeltaiotanolet -> Closure.allnolet
Closure.no_red -> Closure.nored
Reductionops.nored -> Closure.nored
Reductionops.nf_betadeltaiota -> Reductionops.nf_all
Reductionops.whd_betadelta -> Reductionops.whd_betadeltazeta
Reductionops.whd_betadeltaiota -> Reductionops.whd_all
Reductionops.whd_betadeltaiota_nolet -> Reductionops.whd_allnolet
Reductionops.whd_betadelta_stack -> Reductionops.whd_betadeltazeta_stack
Reductionops.whd_betadeltaiota_stack -> Reductionops.whd_all_stack
Reductionops.whd_betadeltaiota_nolet_stack -> Reductionops.whd_allnolet_stack
Reductionops.whd_betadelta_state -> Reductionops.whd_betadeltazeta_state
Reductionops.whd_betadeltaiota_state -> Reductionops.whd_all_state
Reductionops.whd_betadeltaiota_nolet_state -> Reductionops.whd_allnolet_state
Reductionops.whd_eta -> Reductionops.shrink_eta
Tacmach.pf_whd_betadeltaiota -> Tacmach.pf_whd_all
Tacmach.New.pf_whd_betadeltaiota -> Tacmach.New.pf_whd_all
And removed the following ones:
Reductionops.whd_betaetalet
Reductionops.whd_betaetalet_stack
Reductionops.whd_betaetalet_state
Reductionops.whd_betadeltaeta_stack
Reductionops.whd_betadeltaeta_state
Reductionops.whd_betadeltaeta
Reductionops.whd_betadeltaiotaeta_stack
Reductionops.whd_betadeltaiotaeta_state
Reductionops.whd_betadeltaiotaeta
They were unused and having some reduction functions perform eta is confusing
as whd_all and nf_all don't do it.

On the user side, coqtop and coqc take a list of warning names or categories
after -w. No prefix means activate the warning, a "-" prefix means deactivate
it, and "+" means turn the warning into an error. Special categories include
"all", and "default" which contains the warnings enabled by default.
We also provide a vernacular Set Warnings which takes the same flags as argument.
Note that coqc now prints warnings.
The name and category of a warning are printed with the warning itself.
On the developer side, Feedback.msg_warning is still accessible, but the
recommended way to print a warning is in two steps:
1) create it by:
let warn_my_warning =
CWarnings.create ~name:"my-warning" ~category:"my-category"
(fun args -> Pp.strbrk ...)
2) print it by:
warn_my_warning args

Fix bug in Shrink obligations with Program in the process.
Fix implementation of shrink for abstract proofs
- Update doc in term.mli to reflect the fact that let-in's
are part of what is returned by [decompose_lam_assum].

This is a first step to relay location info in an uniform way, as needed
by warnings and other mechanisms.
The location info remains unused for now, but coqtop printing could take
advantage of it if so wished.

This allows a smooth addition of various unsafe flags without wreaking
havoc in the ML codebase.
|
|
|
|
|
|
The rational is that
1. further typing flags may be available in the future
2. it makes it easier to trace and document the argument

This breaks compilation via ocamlbuild, and also leads to awkward
commands via make

If the second allocation causes a collection of the minor heap, the first
allocation will be freed, thus causing a memory corruption.
Note: it only happens when computing the native projection of an opaque
value while the minor heap is almost full.

This patch splits pretty printing representation from IO operations.
- `Pp` is kept in charge of the abstract pretty printing representation.
- The `Feedback` module provides interface for doing printing IO.
The patch continues work initiated for 8.5 and has the following effects:
- The following functions in `Pp`: `pp`, `ppnl`, `pperr`, `pperrnl`,
`pperr_flush`, `pp_flush`, `flush_all`, `msg`, `msgnl`, `msgerr`,
`msgerrnl`, `message` are removed. `Feedback.msg_*` functions must be
used instead.
- Feedback provides different backends to handle output, currently,
`stdout`, `emacs` and CoqIDE backends are provided.
- Clients cannot specify flush policy anymore, thus `pp_flush` et al are
gone.
- `Feedback.feedback` takes an `edit_or_state_id` instead of the old
mix.
Lightly tested: Test-suite passes, Proof General and CoqIDE seem to work.
