clarified Simplifier diagnostics -- simplified ML; unconditional warning for structural mistakes (NB: context of running Simplifier is not visible, and cond_warning ineffective);

folded 'Wellfounded_More_FP' into 'Wellfounded'

folded 'Order_Relation_More_FP' into 'Order_Relation'

support declaration of nonemptiness witnesses in bnf_decl

hide short const name

get rid of 'rel' locale, to facilitate inclusion of 'Order_Relation_More_FP' into 'Order_Relation'

liquidated 'Equiv_Relations_More' -- distinguished between choice-dependent parts and choice-independent parts

compile (importing 'Metis' or 'Main' would have been an alternative)

dissolved 'Fun_More_FP' (a BNF dependency)

moved lemmas from 'Fun_More_FP' to where they belong

moved 'Zorn' into 'Main', since it's a BNF dependency

adapted to move of Wfrec

moved Wfrec to Main, since it is a dependency of cardinals, hence BNFs

added \<newline> symbol, which is used for char/string literals in HOL;

general notion of auxiliary bounds within context; revert_bounds as part of regular unparse_term; avoid special variants of Syntax.string_of_term in Simplifier (e.g. relevant for add-on tracing);

merged

fall-back on old Z3_NON_COMMERCIAL, which simplifies automatic test environments like isatest and mira;

tuned text

tuned

automatically solve proof obligations produced for code equations

use 'disc_exhausts' property both from types on which 'case's take place and on return type

activation of Z3 via "z3_non_commercial" system option (without requiring restart);

tuned;

use the right context in 'unfold_thms id_def'

repaired 'ctr' tactic w.r.t. 'split'

tuned

merged

NEWS;

proper context for clear_simpset: preserve dounds, depth; dismantled obsolete debug_bounds/check_bounds;

clarified context;
