* Add (almost) compatibility with camlp4, without breaking support for camlp5Gravatar letouzey2010-05-19
| | | | | | | | | | | | | | | | | | | | | | | The choice between camlp4/5 is done during configure with flags -usecamlp5 (default for the moment) vs. -usecamlp4. Currently, to have a full camlp4 compatibility, you need to change all "EXTEND" and "GEXTEND Gram" into "EXTEND Gram", and change "EOI" into "`EOI" in grammar entries. I've a sed script that does that (actually the converse), but I prefer to re-think it and check a few things before branching this sed into the build mechanism. lib/compat.ml4 is heavily used to hide incompatibilities between camlp4/5 and try to propose a common interface (cf LexerSig / GrammarSig). A few incompatible quotations have been turned into underlying code manually, in order to make the IFDEF CAMLP5 THEN ... ELSE ... END parsable by both camlp4 and 5. See in particular the fate of <:str_item< declare ... end >> Stdpp isn't used anymore, but rather Ploc (hidden behind local module Loc). This forces to use camlp5 > 5.01. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13019 85f007b7-540e-0410-9357-904b9bb8a0f7
* Nicer representation of tokens, more independant of camlp*Gravatar letouzey2010-05-19
| | | | | | | | | | | | Cf tok.ml, token isn't anymore string*string where first string encodes the kind of the token, but rather a nice sum type. Unfortunately, string*string (a.k.a Plexing.pattern) is still used in some places of Camlp5, so there's a few conversions back and forth. But the penalty should be quite low, and having nicer tokens helps in the forthcoming integration of support for camlp4 post 3.10 git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13018 85f007b7-540e-0410-9357-904b9bb8a0f7

* Remove compile-command pragmas for emacsGravatar letouzey2010-05-19
| | | | | | | | | | | | | | | | | | | These declarations (e.g. make -C .. bin/coqtop.byte) are quite annoying when debugging stuff over the whole archive: all of a sudden, M-x recompile isn't doing what you intended just because you've visited some specific files. Instead: - Feel free to rather add intermediate targets in the Makefile if they aren't there yet. - For avoiding typing the -C with many .. after, you can have a look at my recursively-descending make: http://www.pps.jussieu.fr/~letouzey/download/make.sh which is to be renamed make and placed in a bin dir with more priority than /usr/bin. Beware! I've already add a few bad surprises with this hack, but it's really convenient nonetheless. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13014 85f007b7-540e-0410-9357-904b9bb8a0f7

* Applicative commutative cuts in Fixpoint guard conditionGravatar pboutill2010-05-18
| | | | | | | | | | | | | | | | | | | | | In "(match ... with |... -> fun x -> t end) u", "x" has now the subterm property of "u" in the analysis of "t". Commutative cuts aren't compatible with typing so we need to ensure that term of "x"'s type and term of "u"'s have the same subterm_spec. Consequently,declaration.MRec argument has changed to the inductive name instead of only the number of the inductive in the mutual_inductive family. In subterm_specif and check_rec_call, arguments are stored in a stack. At each lambda, one element is popped to add in renv a smarter subterm_spec for the variable. subterm_spec of constructor's argument was added this way, the job is now done more often. Some eta contracted match branches are now accepted but enforcing eta-expansion of branches might be anyway a recommended invariant. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13012 85f007b7-540e-0410-9357-904b9bb8a0f7
* Improved the efficiency of evars traverals thanks to a split ofGravatar herbelin2010-05-13
| | | | | | | | | | | | | evar_map into a map for defined evars and a map for undefined evars. Even before Spiwack's new proof engine, some Evd.fold were very costly, e.g. in check_evars or progress_evar_map. With the new proof engine, undefined evars traversals are apparently even more common (at least, it improves significantly the complexity of some calls to omega in JordanCurveTheorem - a new factor 5-7 after the factor 5-6 obtained by removal of evar_merge in clenv_fchain in commit 13007, arriving to figures comparable to the 8.3 ones). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13011 85f007b7-540e-0410-9357-904b9bb8a0f7

* Removed an evar_merge in clenv_fchain which not only is incorrect butGravatar herbelin2010-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | is an important cause of inefficiency when the number of evars is large. It is wrong in the sense that it assumes the two sigma given to clenv_fchain to be disjoint. This is true for metas, but not for evars. It used to be useful in some respect when clenv bindings were represented by open_constr, each of them having private evars (see r10151 which introduced this evar_merge), but determining what evars were private which and were shared is hopeless. Since the removal of private sigmas in r12603, evars in clenv bindings are assumed to be extended monotonically and clenv_fchain should only have to take the most recent evars - assumed to be the first argument - instead of a union. The function clenv_fchain remains anyway fragile since it is asymmetric. More should be done to clean it up so that it receives only one - unambiguous - evars argument, what would mean actually, receiving only one clausenv and the second argument being just a template pair (t:T). The call to evar_merge was source of inefficiency. On some calls to omega in contrib JordanCurveTheorem, removing it reduces the execution time by a factor larger than 5 (from 400s down to 70s on my Core 2 Duo). git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@13007 85f007b7-540e-0410-9357-904b9bb8a0f7

| | | | | | | | | | | | | | | In checker: - delta_resolver inferred by the module system is checked through regular delta reduction steps - the old mind_equiv field of mutual_inductive is simulated through a special table in environ - small optimization, if the signature and the implementation of a module are physically equal (always happen for the toplevel module of a vo) then the checker checks only the signature. In kernel - in names i have added two special equality functions over constant and inductive names for the checker, so that the checker does not take in account the cannonical name inferred by the module system. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@12977 85f007b7-540e-0410-9357-904b9bb8a0f7
