added "trace_meson" configuration option, replacing old-fashioned reference

added "trace_metis" configuration option, replacing old-fashioned references

do not mention unqualified names, now that 'global' and 'local' are gone

simplified proof

avoid generating several formulas with the same name ("tfrees")

major reorganization/simplification of HOLCF type classes: removed profinite/bifinite classes and approx function; universal domain uses approx_chain locale instead of bifinite class; ideal_completion locale does not use 'take' functions, requires countable basis instead; replaced type 'udom alg_defl' with type 'sfp'; replaced class 'rep' with class 'sfp'; renamed REP('a) to SFP('a);

add lemma finite_deflation_intro

add lemmas finite_deflation_imp_compact, cast_below_cast_iff

move lemmas to Deflation.thy

simplify proofs of powerdomain inequalities

new lemmas about lub

paramify new skolems just like old ones (cf. reveal_old_skolem_terms)

fixed two bugs in new skolemizer: instantiations now take types into consideration, and rotate_tac is given the proper offset

correctly handle multiple copies of the same axiom with the same types

put two operations in the right order

reintroduce old "unify_prem_with_concl" code to avoid reaching unification bound + primitive handling for polymorphism

apply "assume_tac" directly on the right assumption, using "rotate_tac" -- this ensures that the desired unifications are performed

instantiate foralls and release exists in the order described by the topological order

reverted 0bfaaa81fc62, since "Thm.rename_boundvars" can't be relied upon to give unique names to bound variables

renamed internal function

hack in MESON to make it less likely that variables (e.g. "x") get renamed (e.g. "xa") when resolving

tuned header

rename bound variables after skolemizing, if the axiom of choice is available

tuning

merged

avoid dependency on "int"

make "cnf_axiom" work (after a fashion) in the absence of the axiom of choice

added "meson_choice" attribute as a step towards making (less powerful versions of) Meson/Metis/Sledgehammer work without the axiom of choice

compute quantifier dependency graph in new skolemizer

tuning

compute substitutions in new skolemizer

encode axiom number and cluster number in all zapped quantifiers to help discharging new skolemizer assumptions

reintroduced code that keeps track of whether the Isabelle and Metis proofs are in sync -- generalized to work with the new skolemizer

encode number of skolem assumptions in them, for more efficient retrieval later

move functions closer to where they're used

Skolemizer tweaking

"meson_new_skolemizer" -> "metis_new_skolemizer" option (since Meson doesn't support the new skolemizer (yet))

finished renaming file and module

rename file

ignore Skolem assumption (if any)

second step in introducing the new Skolemizer -- notably, added procedure for discharging Skolem assumptions

first step towards a new skolemizer that doesn't require "Eps"

avoiding instable rotate_tac and using the nice Subgoal.FOCUS_PREMS instead

adding test case for interpretation of arguments that are predicates simply as input

no longer declare .psimps rules as [simp]. This regularly caused confusion (e.g., they show up in simp traces when the regular simp rules are disabled). In the few places where the rules are used, explicitly mentioning them actually clarifies the proof text.
