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 --- checker/mod_checking.ml | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'checker/mod_checking.ml') diff --git a/checker/mod_checking.ml b/checker/mod_checking.ml index bc4ea7c69..ebe44997d 100644 --- a/checker/mod_checking.ml +++ b/checker/mod_checking.ml @@ -35,7 +35,7 @@ let check_constant_declaration env kn cb = let _ = infer_type envty ty in (match body_of_constant cb with | Some bd -> - let j = infer env' (force_constr bd) in + let j = infer env' bd in conv_leq envty j ty | None -> ()) | PolymorphicArity(ctxt,par) -> -- cgit v1.2.3
