* Revised infrastructure for lazy loading of opaque proofsGravatar letouzey2013-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* kernel/declarations becomes a pure mliGravatar letouzey2013-02-26
- constr_substituted and lazy_constr are now in a dedicated kernel/lazyconstr.ml - the functions that were in declarations.ml (mostly substitution utilities and hashcons) are now in kernel/declareops.ml git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@16250 85f007b7-540e-0410-9357-904b9bb8a0f7
