From f5ab2e37b0609d8edb8d65dfae49741442a90657 Mon Sep 17 00:00:00 2001 From: letouzey Date: Tue, 2 Apr 2013 22:08:44 +0000 Subject: Revised infrastructure for lazy loading of opaque proofs Get rid of the LightenLibrary hack : no more last-minute collect of opaque terms and Obj.magic tricks. Instead, we make coqc accumulate the opaque terms as soon as constant_bodies are created outside sections. In these cases, the opaque terms are placed in a special table, and some (DirPath.t * int) are used as indexes in constant_body. In an interactive session, the local opaque terms stay directly stored in the constant_body. The structure of .vo file stays similar : magic number, regular library structure, digest of the first part, array of opaque terms. In addition, we now have a final checksum for checking the integrity of the whole .vo file. The other difference is that lazy_constr aren't changed into int indexes in .vo files, but are now coded as (substitution list * DirPath.t * int). In particular this approach allows to refer to opaque terms from another library. This (and accumulating substitutions in lazy_constr) seems to greatly help decreasing the size of opaque tables : -20% of vo size on the standard library :-). The compilation times are slightly better, but that can be statistic noise. The -force-load-proofs isn't active anymore : it behaves now just like -lazy-load-proofs. The -dont-load-proofs mode has slightly changed : opaque terms aren't seen as axioms anymore, but accessing their bodies will raise an error. Btw, API change : Declareops.body_of_constant now produces directly a constr option instead of a constr_substituted option git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16382 85f007b7-540e-0410-9357-904b9bb8a0f7 --- plugins/xml/xmlcommand.ml | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'plugins/xml') diff --git a/plugins/xml/xmlcommand.ml b/plugins/xml/xmlcommand.ml index a34d4a682..ddc4725c3 100644 --- a/plugins/xml/xmlcommand.ml +++ b/plugins/xml/xmlcommand.ml @@ -229,8 +229,7 @@ let mk_constant_obj id bo ty variables hyps = Acic.Constant (Names.Id.to_string id,None,ty,params) | Some c -> Acic.Constant - (Names.Id.to_string id, Some (Unshare.unshare (Lazyconstr.force c)), - ty,params) + (Names.Id.to_string id, Some (Unshare.unshare c), ty,params) ;; let mk_inductive_obj sp mib packs variables nparams hyps finite = -- cgit v1.2.3
