2013-02-21A slightly more efficient test of well-typedness of restriction ofherbelin
evars (though this might be slighty more costly). This incidentally solves Appel's part of bug #2830 even though a conceptual problem around the interaction of unification with the proof engine has to be solved. Indeed, what to do when unification, called as part of a tactic, solves or refines the current goal by side effect. Somehow, unifyTerms or tclEVARS should take this possibility into consideration, either by forbidding the refinement of the current goal by side effect, or by acknowledging this refinement by producing new subgoals. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16232 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-02-17Added propagation of evars unification failure reasons for betterherbelin
error messages. The architecture of unification error handling changed, not helped by ocaml for checking that every exceptions is correctly caught. Report or fix if you find a regression. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16205 85f007b7-540e-0410-9357-904b9bb8a0f7
2013-02-17Revised the Ltac trace mechanism so that trace breaking due toherbelin
interleaving of ltac and ml code is not visible (this particularly applies to ltac notation ring, which calls ml-level ring_lookup and Ring again at the ltac level, resulting in non-localisation of "ring" errors). Added also missing LtacLocated checks in Class_instance and Proofview. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16204 85f007b7-540e-0410-9357-904b9bb8a0f7

2012-12-04Backtrack on activating scopes with type casts (was r15978).herbelin
IT happens that there are some other uses of casts, e.g. in nat_int de MathClasses which uses a notation 0 for some class constructor zero, and a cast (0:nat) to force this notation 0 to represent the instance O in nat of the class of types having a zero (eventually, 0, i.e. "zero nat O" and "O" are convertible but the information of being a class instance is lost). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16024 85f007b7-540e-0410-9357-904b9bb8a0f7
2012-12-04Revised the strategy for automatic insertion of spaces when printingherbelin

2012-11-25Fixed bug #2930: folded let-in's were hiding a violation to the occurherbelin
check condition in pattern-unification, resulting in the instantiation of evars by terms depending on themselves, henceforth leading eventually to a stack overflow. Occur-check in the arguments of evars was also missing.

2012-11-18Hurkens' paradox on Type (r15973 and r15977) needs two (non-Set)herbelin
universes. As it uses eq_rect on Type(2), the arguments of eq_rect has to be in Type(3) and compiling the standard library now needs one more universe!
