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 --- library/states.ml | 2 -- 1 file changed, 2 deletions(-) (limited to 'library/states.ml') diff --git a/library/states.ml b/library/states.ml index 9d15dfc6c..eb597670f 100644 --- a/library/states.ml +++ b/library/states.ml @@ -23,8 +23,6 @@ let (extern_state,intern_state) = extern_intern Coq_config.state_magic_number in (fun s -> let s = ensure_suffix s in - if !Flags.load_proofs <> Flags.Force then - Errors.error "Write State only works with option -force-load-proofs"; raw_extern s (freeze())), (fun s -> let s = ensure_suffix s in -- cgit v1.2.3
