contextifying the compilation of the predicate compiler

removed unused Predicate_Compile_Set

avoiding fishing for split_asm rule in the predicate compiler

contextifying the proof procedure in the predicate compiler

making flat triples to nested tuple to remove general triple functions

reduced the debug output functions from 2 to 1

some improvements thanks to Makarius source code review

adding proof procedure for cases rule with tuples; adding introduction rule for negated premises; improving proof procedure with negated premises

enabling a previously broken example of the predicate compiler again

improving handling of case expressions in predicate rewriting

adding depth_limited_random compilation to predicate compiler

a new simpler random compilation for the predicate compiler

reviving the classical depth-limited computation in the predicate compiler

cleaning the function flattening

generalized split transformation in the function flattening

only adding lifted arguments to item net in the function flattening; correcting indentation; removing dead code

restructuring function flattening

renaming mk_prems to flatten in the function flattening

simplifying function flattening

removed warning_count (known causes for warnings have been resolved)

remove the iteration counter from Sledgehammer's minimizer

merged

start work on direct proof reconstruction for Sledgehammer

renamed "e_full" and "vampire_full" to "e_isar" and "vampire_isar"; "full" sounds like "full types" or something, not like a structured Isar proof -- at some point I hope to make this an option that's orthogonal to the prover

move all ATP setup code into ATP_Wrapper

move the Sledgehammer Isar commands together into one file; this will make easier to add options and reorganize them later

more Sledgehammer refactoring

use a proof context instead of a local theory

provide a hook to safely manipulate verification conditions

replaced old-style Drule.add_axiom by Specification.axiomatization

removed e-mail address from error message

merged

tuned whitespace

handle hidden polymorphism in class target (without class target syntax, though)

replaced Theory.add_axioms(_i) by more primitive Theory.add_axiom;

replaced PureThy.add_axioms by more basic Drule.add_axiom, which is old-style nonetheless;

add_axiom: axiomatize "unconstrained" version, with explicit of_class premises; more uniform add_axiom/add_def;

Logic.mk_of_sort convenience;

more explicit invented name;

minor renovation of old-style 'axioms' -- make it an alias of iterated 'axiomatization';

do not open ML structures;

modernized overloaded definitions;

standard headers;

slightly more uniform definitions -- eliminated old-style meta-equality;

eliminated old constdefs;

corrected setup for of_list

renamed varify/unvarify operations to varify_global/unvarify_global to emphasize that these only work in a global situation;

added lemma infinite_Un

Check that argument is not a 'Bound' before calling fastype_of.

typedef etc.: no constraints;

allow sort constraints in HOL/typedef;

allow sort constraints in HOL/typedef and related HOLCF variants;

OuterParse.type_args_constrained;

support type arguments with sort constraints;

typedecl: no sort constraints; prefer Name.invents over old-style Name.variant_list;

eliminated slightly odd typedecl_wrt in favour of explicit predeclare_constraints;

typedecl: no sort constraints;

eliminated slightly odd typedecl_wrt in favour of explicit predeclare_constraints (which also works for recursive types); allow sort constraints; misc tuning and clarification;

Added product measure space

added type constraints to make SML/NJ happy
