2020-02-13[build] Consolidate stdlib's .v files under a single directory.Emilio Jesus Gallego Arias
Currently, `.v` under the `Coq.` prefix are found in both `theories` and `plugins`. Usually these two directories are merged by special loadpath code that allows double-binding of the prefix. This adds some complexity to the build and loadpath system; and in particular, it prevents from handling the `Coq.*` prefix in the simple, `-R theories Coq` standard way. We thus move all `.v` files to theories, leaving `plugins` as an OCaml-only directory, and modify accordingly the loadpath / build infrastructure. Note that in general `plugins/foo/Foo.v` was not self-contained, in the sense that it depended on files in `theories` and files in `theories` depended on it; moreover, Coq saw all these files as belonging to the same namespace so it didn't really care where they lived. This could also imply a performance gain as we now effectively traverse less directories when locating a library. See also discussion in #10003

2013-08-23Fixing an incompleteness of the ring/field tacticsamahboub
The problem occurs when a customized ring/field structure declared with a so-called "morphism" (see 24.5 in the manual) tactic allowing to reify (numerical) constants efficiently. When declaring a ring/field structure, the user can provide a cast function phi in order to express numerical constants in another type than the carrier of the ring. This is useful for instance when the ring is abstract (like the type R of reals) and one needs to express constants to large to be parsed in unary representation (for instance using a phi : Z -> R). Formerly, the completeness of the tactic required (phi 1) (resp. (phi 0)) to be convertible to 1 (resp. 0), which is not the case when phi is opaque. This was not documented untill recently but I moreover think this is also not desirable since the user can have good reasons to work with such an opaque case phi. Hence this commit: - adds two constructors to PExpr and FExpr for a correct reification - unplugs the optimizations in reification: optimizing reification is much less efficient than using a cast known to the tactic. TODO : It would probably be worth declaring IZR as a cast in the ring/field tactics provided for Reals in the std lib. The completeness of the tactic formerly relied on the fact that git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16730 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-07-05ZArith + other : favor the use of modern names instead of compat notationsletouzey
- For instance, refl_equal --> eq_refl - Npos, Zpos, Zneg now admit more uniform qualified aliases N.pos, Z.pos, Z.neg. - A new module BinInt.Pos2Z with results about injections from positive to Z - A result about Z.pow pushed in the generic layer - Zmult_le_compat_{r,l} --> Z.mul_le_mono_nonneg_{r,l} - Using tactic Z.le_elim instead of Zle_lt_or_eq - Some cleanup in ring, field, micromega (use of "Equivalence", "Proper" ...) - Some adaptions in QArith (for instance changed Qpower.Qpower_decomp) - In ZMake and ZMake, functor parameters are now named NN and ZZ instead of N and Z for avoiding confusions git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15515 85f007b7-540e-0410-9357-904b9bb8a0f7
