    Changed the behavior of -relevant-equality so that Set is not

    andrejbauer authored committed
    considered small, in the sense that a type in Set does not
    get equality in Prop. This is the desired behavior for the
    homotopy interpretation where Set cannot be interpreted, say,
    as the intersection of hset and the lowest universe.
    
    It would still be good to make absence of -relevant-equality
    contaminant so that we cannot accidentally use the standard
    library when the option is present.
    
    And yes, there is no hope of compiling the standard library
    with this option turned on.

    Patch by Hugo Herbelin.

    mattam82 authored committed
     Added an option -relevant-equality to Coq which makes the
     logic compatible with a model such as the univalent model
     where proofs of equality are informative as soon as they
     involve elements in some Type level. This has an effect on
     the level in which universe-polymorphic inductive types are
     placed, which can be higher than w/o the option, and on
     which singleton eliminations are allowed, which can be less
     than w/o the option.
    
    How indices contribute:
    - Indices in A:Prop do not contribute to the level of an inductive nor
      on whether singleton elimination is allowed or not.
    - We chose to interpret Set as a sort in which proofs of equality are
      irrelevant (i.e. a sort in which Streicher's K holds). Hence indices
      in A:Set do not contribute to the level of the inductive. In
      particular, elimination from "Inductive eq (A:Set) (a:A) : A -> Prop
      := refl : eq A a a." is unrestricted. Similarly, the default lower
      level of polymorphic "Inductive eq (A:Set) (a:A) : A -> Type := refl
      : eq A a a." is Prop.
    - Indices in A:Type contribute to raising the level of a
      universe-polymorphic type. E.g. "Inductive eq (A:Type (* u *) ) (a:A) :
      A -> Type := refl : eq A a a." is in "Type (* u *)". Similarly,
      singleton elimination is forbidden from "Inductive eq (A:Type) (a:A)
      : A -> Prop := refl : eq A a a.".
    
    Remarks:
    - The modification applies uniformly to all inductive types with
      indices, not only those resembling equality.
    - The standard library stops to compile when the option is activated.
    - We could have been finer, and only restrict singleton eliminations
      dynamically depending on the level of the effective sort
      used. E.g. with "Inductive eq (A:Type) (a:A) : A -> Prop := refl :
      eq A a a.", we could have allowed "eq nat" to be eliminable to every
      sorts (because nat can be finally be put in Set and not in some
      higher Type). With this, a larger amount of the standard library
      could be compiled by reasoning in Set rather than in Type.
      However, this is not implemented.

  3. Turn mltop.ml4 into a regular ocaml file

    letouzey authored
     The IFDEF's in mltop.ml4 were there to support platforms with
     a native ocaml compiler but no dynlink.cmxa, a situation that
     should be pretty rare in the Coq community nowadays (playing
     with coqtop on ARM, anyone ?). So we now refuse to build
     a native coqtop unless dynlink.cmxa exists (cf ./configure),
     and we explain how to create a dummy one if necessary
     (cf dev/dynlink.ml). This way, we can clean-up mltop.ml,
     and remove ugly special rules in Makefile and myocamlbuild
    
     NB: I checked that this shouldn't have any impact on Coq's
     debian packages on exotic architectures (arm, mips, ...),
     since apparently on these architectures no ocamlopt at all
     are shipped, and coq packages are already byte-only

  12. remove dumptree.ml4

    letouzey authored
     This file was providing the "Dump Tree" command to display
     the state of a proof in XML. This command has been broken since
     the integration of Arnaud's proof engine. Nobody cared enough
     to adapt this to the new framework, moreover the trend is
     rather now to use the xml-base dialog mode of coqtop,
     so I simply remove this obsolete code.

  2. Repair the configure after Hugo's last "repair" ;-)

    letouzey authored
     Ok, I wasn't aware of the funny behavior of cd in presence of $CDPATH.
     But the last "repair" was worse, trying to write into non-existing file
     theories/config/coq_config.ml
    
     Things should be better now:
    
     * no more Coq_config.theories_dirs at all, since it was completely unused :-)
    
     * concerning Coq_config.plugins_dirs, we list them without any "cd" into plugins,
       hence keeping the "plugins/" part in their paths, and adapt accordingly
       the only use (!) of plugins_dirs, in coq_makefile

  4. More accurate timings for "Time foo"

    letouzey authored
     The elapsed time in seconds was computed via a difference of Unix.time(),
     but these Unix.time() aren't precise enough (just a number of seconds),
     and a difference is hence even less precise.  We now use Unix.gettimeofday,
     and round the time difference to the millisecond.
