From 886a9c2fb25e32bd87b3fce38023b3e701134d23 Mon Sep 17 00:00:00 2001 From: Emilio Jesus Gallego Arias Date: Wed, 27 Dec 2017 20:22:23 +0100 Subject: [econstr] Continue consolidation of EConstr API under `interp`. This commit was motivated by true spurious conversions arising in my `to_constr` debug branch. The changes here need careful review as the tradeoffs are subtle and still a lot of clean up remains to be done in `vernac/*`. We have opted for penalize [minimally] the few users coming from true `Constr`-land, but I am sure we can tweak code in a much better way. In particular, it is not clear if internalization should take an `evar_map` even in the cases where it is not triggered, see the changes under `plugins` for a good example. Also, the new return type of `Pretyping.understand` should undergo careful review. We don't touch `Impargs` as it is not clear how to proceed, however, the current type of `compute_implicits_gen` looks very suspicious as it is called often with free evars. Some TODOs are: - impargs was calling whd_all, the Econstr equivalent can be either + Reductionops.whd_all [which does refolding and no sharing] + Reductionops.clos_whd_flags with all as a flag. --- tactics/tactics.ml | 1 - 1 file changed, 1 deletion(-) (limited to 'tactics/tactics.ml') diff --git a/tactics/tactics.ml b/tactics/tactics.ml index 7e281e2fe..945b178a1 100644 --- a/tactics/tactics.ml +++ b/tactics/tactics.ml @@ -1991,7 +1991,6 @@ let exact_proof c = Proofview.Goal.enter begin fun gl -> Refine.refine ~typecheck:false begin fun sigma -> let (c, ctx) = Constrintern.interp_casted_constr (pf_env gl) sigma c (pf_concl gl) in - let c = EConstr.of_constr c in let sigma = Evd.merge_universe_context sigma ctx in (sigma, c) end -- cgit v1.2.3
