2013-10-05Removing dubious use of evarmap manipulating functions in printingppedrot
related code. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16851 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-10-05Moving side effects into evar_map. There was no reason to keep anotherppedrot
state out of one we were threading all the way along. This should be safer, as one cannot forego side effects accidentally by manipulating explicitly the [sigma] container. Still, this patch raised the issue of badly used evar maps. There is an ad-hoc workaround (i.e. a hack) in Rewrite to handle the fact it uses evar maps in an unorthodox way. Likewise, that mean we have to revert all contrib patches that added effect threading... There was also a dubious use of side effects in their toplevel handling, that duplicates them, leading to the need of a rather unsafe List.uniquize afterwards. It should be investigaged. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16850 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-09-18At least made the evar type opaque! There are still 5 remaining unsafeppedrot
casts of ints to evars. - 2 in Evarutil and Goal which are really needed, even though the Goal one could (and should) be removed; - 2 in G_xml and Detyping that are there for completeness sake, but that might be made anomalies altogether; - 1 in Newring which is quite dubious at best, and should be fixed. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16786 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-09-18Removing almost all new_untyped_evar, and a bunch of Evd.add.ppedrot
Ultimately all evars should be created with respect to a given evar map, instead of using a global counter. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16783 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-08-08State Transaction Machinegareuselesinge
The process_transaction function adds a new edge to the Dag without executing the transaction (when possible). The observe id function runs the transactions necessary to reach to the state id. Transaction being on a merged branch are not executed but stored into a future. The finish function calls observe on the tip of the current branch. Imperative modifications to the environment made by some tactics are now explicitly declared by the tactic and modeled as let-in/beta-redexes at the root of the proof term. An example is the abstract tactic. This is the work described in the Coq Workshop 2012 paper. Coq is compile with thread support from now on. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16674 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-05-09A uniformization step around understand_* and interp_* functions.herbelin
- Clarification of the existence of three algorithms for solving unconstrained evars: - the type-class mechanism - the heuristics for solving pending conversion problems and multi-candidates - Declare Implicit Tactic (when called from tactics) Main function for solving unconstrained evars (when not using understand): Pretyping.solve_remaining_evars - Clarification of the existence of three corresponding kinds of errors when reporting about unsolved evars: Main function for checking resolution of evars independently of the understand functions: Pretyping.check_evars_are_solved - Introduction of inference flags in pretyping for governing which combination of the algorithms to use when calling some understand function; there is also a flag of expanding or not evars and for requiring or not the resolution of all evars - Less hackish way of managing Pretyping.type_constraint: all three different possibilities are now represented by three different constructors - Main semantical changes done: - solving unconstrained evars and reporting is not any longer mixed: one first tries to find unconstrained evars by any way possible; one eventually reports on the existence of unsolved evars using check_evars_are_solved - checking unsolved evars is now done by looking at the evar map, not by looking at the evars occurring in the terms to pretype; the only observed consequence so far is in Cases.v because of subterms (surprisingly) disappering after compilation of pattern-matching - the API changed, see dev/doc/changes.txt Still to do: - Find more uniform naming schemes: - for distinguishing when sigma is passed as a reference or as a value (are used: suffix _evars, prefix e_) - for distinguishing when evars are allowed to remain uninstantiated or not (are used: suffix _evars, again, suffix _tcc, infix _open_) - be more consistent on the use of names evd/sigma/evars or evdref/evars - By the way, shouldn't "understand" be better renamed into "infer" or "preinfer", or "pretype". Grammatically, "understanding a term" looks strange. - Investigate whether the inference flags in tacinterp.ml are really what we want (e.g. do we really want that heuristic remains activated when typeclasses are explicitly deactivated, idem in Tacinterp.interp_open_constr where flags are strange). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16499 85f007b7-540e-0410-9357-904b9bb8a0f7

2013-04-22code simplifications concerning Summaryletouzey
- Most of the time, the table registered via Summary.declare_summary is just a single reference. A new function Summary.ref now allows to both declare this ref and register it to summary in one shot. - Clarifications concerning the role of [init_function]. For statically registered tables that don't need a special initializer, just do nothing there (see the new Summary.nop function). Beware: now that Summary exports a function named "ref", any code that do an "open Summary" will probably fail to compile. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16441 85f007b7-540e-0410-9357-904b9bb8a0f7
