2019-06-21Coq: even more robust handling of unknown goalsBrian Campbell
2019-06-21Coq: better handling of unknown constraintsBrian Campbell
Move the tactic forward so that preprocessing can't try silly things, simpl to get rid of embedded proofs.
2019-06-20Coq: avoid some unnecessary reduction in the constraint solverBrian Campbell
2019-06-13Coq: add eq_bit built-inBrian Campbell
2019-06-11Coq: add concatenation operator for polymorphic vectorsBrian Campbell
2019-06-06Coq: more aggressive rewriting before solvingBrian Campbell
Solves some ARM model constraints much more quickly
2019-06-06Coq: tweak bool to Z to use less memoryBrian Campbell
2019-06-05Coq: exploit arithmetic solver for some mixed integer/bool problems.Brian Campbell
2019-06-05Coq: generalize proof terms before main solverBrian Campbell
Ensures that dependencies in proofs don't affect rewriting.
2019-06-04Coq: more constraint solvingBrian Campbell
- make the exists, iff solver handle more cases - avoid exposing omega to goals with local definitions involving proofs
2019-06-03Coq: experiment with another boolean iff solving methodBrian Campbell
2019-05-29Coq: more solver improvementsBrian Campbell
- don't clear boolean local definitions - we need those now - some boolean disjunction fixes
2019-05-29Coq: need a proof for _shr32Brian Campbell
2019-05-28Coq: more constraint solvingBrian Campbell
- add division lemma - deal with some awkward \/ constraints from asl_parser - try simple integer comparison proofs before omega (which can blow up on trivial properties in large contexts)
2019-05-24Coq: switch to computable versions of BBV shiftsBrian Campbell
2019-05-23Coq: solve some division constraintsBrian Campbell
2019-05-22Coq: tweak disjunctions tactic with subst to support more constraintsBrian Campbell
2019-05-21Coq: remove premature unfolding of local definitionsBrian Campbell
2019-05-20Coq: fix property extraction bug, solve some constraints involving setsBrian Campbell
2019-05-19Coq: proper definitions for some undefined value functionsBrian Campbell
That is, undefined_bitvector, undefined_unit, internal_pick.
2019-05-15Coq: constraint solving for aarch64Brian Campbell
Also split out main solver tactic to make debugging a little easier.
2019-04-19Coq: more robust handling of unknown constraintsBrian Campbell
2019-04-16Coq: make bools_of_int (and hence get_slice_int) compute wellBrian Campbell
2019-04-16Coq: add specialised shiftsBrian Campbell
2019-04-10Coq: update prompt monad to match the Lem, and port the state monad/liftingBrian Campbell
NB: requires minor changes in the models
2019-04-04Coq: improve solver on conjunctions, Euclidean division/moduloBrian Campbell
2019-03-27Coq: add a little knowledge about ZEuclid.divBrian Campbell
2019-03-27Coq: replace firstorder with less expensive tacticsBrian Campbell
2019-03-19Coq: more work on testsBrian Campbell
- skip a few more that aren't supported yet - produce better debugging information (in particular, in the right order) - avoid some autocasts that aren't supported yet and are usually unnecessary - Handle more constraints like `8 * n = 8 * ?Goal`
2019-03-15Coq: some progress on the test suiteBrian Campbell
Rewrite <> true/false in goals. Correct implicits in record and variant types. Use expanded valspecs from the type checker in axioms. Allow list notations in type definitions. Skip some not-yet-supported tests.
2019-03-15Coq: better loop handling, discharge some related proof obligationsBrian Campbell
2019-03-12Coq: try non-linear nia solver tooBrian Campbell
2019-03-12Coq: fix some boolean issues seen in armBrian Campbell
Fixes bad precedence issues, removes an out-of-date special case that's not necessary, and solves more goals.
2019-03-07Coq: apply a little brute force in some boolean goalsBrian Campbell
2019-03-05Coq: firstorder is better at the boolean goalsBrian Campbell
2019-03-05Coq: use setoid rewriting to apply under an existential binderBrian Campbell
2019-03-01Coq: add a little bit of boolean solvingBrian Campbell
Just enough for RISC-V to go through
2019-02-28Coq: remove unused library definitionsBrian Campbell
2019-02-28Coq: some work on bool simplificationBrian Campbell
This introduces some simplification of informative booleans, but tries too hard to eliminate all of the existentials resulting in difficulties in and/or trees.
2019-01-24Start supporting informative bool types in Coq backendBrian Campbell
2019-01-09Coq: the division used in smt.sail should be EuclideanBrian Campbell
2019-01-09Coq: add truncateLSB and import Zeuclid by defaultBrian Campbell
2018-12-27Coq: make solver try hints before stripping away existentialsBrian Campbell
(which allows us to avoid a Coq bug where the proof isn't recorded correctly)
2018-12-19Coq: handle existentials in hypotheses during solving, add max_nat, better castsBrian Campbell
2018-12-17Adapt Coq and termination measure support to typechecker changesBrian Campbell
Also output termination measures in Sail printer
2018-11-21Coq: min_natBrian Campbell
2018-11-21Coq: add equality for records and polymorphic vectorsBrian Campbell
2018-09-19Coq: more fixes for AArch64Brian Campbell
- implement set_slice and set_slice_int - lemmas for more constraints - make real sqrt visible - unfolding list membership needs andb and orb to be handled first
2018-09-17Coq: solve some constraint/type errors with AArch64Brian Campbell
- hints for dotp - handle exists separately when trying eauto to keep search depth low - more uniform existential handling (i.e., we now handle all existentials in the way we used to only handle existentials around atoms)
2018-09-12Coq: make generic_eq work on more typesBrian Campbell
