more precise type Symbol_Pos.text;
geralized ML_Context.inherit_env;
wenzelm [Wed, 18 Mar 2009 21:55:38 +0100] rev 30573
de-camelized Symbol_Pos;
wenzelm [Wed, 18 Mar 2009 20:03:01 +0100] rev 30572
Library.merge/OrdList.union: optimize the important special case where the tables coincide -- NOTE: this changes both the operational behaviour and the result for non-standard eq/ord notion;
wenzelm [Wed, 18 Mar 2009 19:11:26 +0100] rev 30571
reduced verbosity;
haftmann [Wed, 18 Mar 2009 15:23:52 +0100] rev 30570
made SML/NJ happy
haftmann [Wed, 18 Mar 2009 11:57:28 +0100] rev 30569
tuned interpunctation
wenzelm [Tue, 17 Mar 2009 19:53:57 +0100] rev 30568
strip_abss: always strip abstractions as far as possible, without keeping alternatives (which appear to be redundant anyway, but cause significant slowdown since discrimination nets collapse abstractions);
wenzelm [Tue, 17 Mar 2009 19:06:04 +0100] rev 30567
close/all_assm_tac: finish all subgoals from left to right (cf. Proof.goal_tac a28d83e903ce) -- NB: ALLGOALS/THEN_ALL_NEW operate from right to left;
wenzelm [Tue, 17 Mar 2009 16:55:21 +0100] rev 30566
reverted abbreviations: improved performance via Item_Net.T;
wenzelm [Tue, 17 Mar 2009 15:35:27 +0100] rev 30565
export match_rew -- useful for implementing "procs" for rewrite_term;

clean up proofs
wenzelm [Tue, 17 Mar 2009 14:12:43 +0100] rev 30560
adapted to general Item_Net;
wenzelm [Tue, 17 Mar 2009 14:12:06 +0100] rev 30559
turned structure NetRules into general Item_Net, which is loaded earlier;
wenzelm [Tue, 17 Mar 2009 14:09:20 +0100] rev 30558
renamed Tactic.taglist/untaglist/orderlist to tag_list/untag_list/order_list (in library.ML);
wenzelm [Tue, 17 Mar 2009 13:33:21 +0100] rev 30557
goal_tac: finish marked assumptions from left to right -- corresponds better with the strategy of etac, with significant performance gains in some situations;
wenzelm [Tue, 17 Mar 2009 12:10:42 +0100] rev 30556
eq_assumption: slightly more efficient by checking (open) result of Logic.assum_problems directly;
tuned;
wenzelm [Tue, 17 Mar 2009 12:09:43 +0100] rev 30555
tuned aeconv: test plain aconv before expensive eta_contract;
wenzelm [Mon, 16 Mar 2009 23:52:30 +0100] rev 30554
substantial speedup of assumption and elim-resolution: Logic.assum_problems refrains from eager application of parameters, discriminate via Term.could_unify before invoking full unification (assumes terms in beta-normal form, as do higher term net operations anyway);
wenzelm [Mon, 16 Mar 2009 23:39:44 +0100] rev 30553
refined is_norm_hhf: reject beta-redexes (rules based on term nets or could_unify assume normal form), also potentially faster by avoiding expensive Envir.beta_eta_contract;
wenzelm [Mon, 16 Mar 2009 23:36:55 +0100] rev 30552
provide Simplifier.norm_hhf(_protect) as regular simplifier operation;
wenzelm [Mon, 16 Mar 2009 19:40:03 +0100] rev 30551
method parser: pass proper context;

wenzelm [Mon, 16 Mar 2009 18:24:30 +0100] rev 30549
