afaf0e3dd7 Add a fast-path to _coerce_exprs. (#7995)
When the inputs are already the same sort, we can skip most of the
coercion logic and just return.

Currently, `_coerce_exprs` is by far the most expensive part of
building up many common Z3 ASTs, so this fast-path is a substantial
speedup for many use-cases.

0d85b86334 Update Z3_mk_datatype_sort API to accept array of sort parameters and add Z3_mk_polymorphic_datatype (#7966)
* Initial plan

* Update Z3_mk_datatype_sort API to accept array of parameters

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Update language bindings for parametric datatype sort API

- Python: Updated DatatypeSort() to accept optional params list
- OCaml: Added mk_sort_ref_p/mk_sort_ref_ps for parametric datatypes
- .NET: Added MkDatatypeSortRef() methods with optional params
- Java: Added mkDatatypeSortRef() methods with optional params
- All changes maintain backward compatibility

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Fix .NET build error - rename params to parameters

The 'params' keyword is reserved in C#, causing compilation errors.
Renamed parameter from 'params' to 'parameters' in MkDatatypeSortRef methods.

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Add unit test for parametric datatypes

Added test_parametric_datatype.cpp to demonstrate polymorphic datatypes.
The test creates two concrete instantiations of a generic pair concept:
- pair_int_real with fields (first:Int, second:Real)
- pair_real_int with fields (first:Real, second:Int)
Then verifies that accessors work correctly and type checking is enforced.

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Implement polymorphic type variables support for parametric datatypes

- Modified datatype_decl_plugin to allow type variables as parameters
- Updated mk_datatype_decl to extract type variables from field sorts
- Type variables are collected in order of first appearance
- Revised unit test to use Z3_mk_type_variable for polymorphic datatypes
- Test creates pair datatype with type variables alpha and beta
- Successfully instantiates with concrete types (pair Int Real) and (pair Real Int)
- Verifies accessor types match and equality terms are well-typed
- All tests pass

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Add Z3_mk_polymorphic_datatype API and refactor datatype creation

- Added new API Z3_mk_polymorphic_datatype to z3_api.h
- Renamed static mk_datatype_decl to api_datatype_decl in api_datatype.cpp
- Modified api_datatype_decl to accept explicit type parameters
- Updated all callers to use renamed function
- Added test_polymorphic_datatype_api demonstrating new API usage
- Both tests pass successfully

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Remove type variable collection logic from constructors

Removed the logic for collecting type variables from field sorts based on constructors.

* Update comments on parameter handling in api_datatype.cpp

Clarify usage of parameters in API documentation.

* Fix OCaml build error - use list instead of array for mk_datatype_sort

Changed mk_sort_ref to pass empty list [] instead of empty array [||].
Changed mk_sort_ref_p to pass params list directly instead of converting to array.
Z3native.mk_datatype_sort expects a list, not an array.

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Add polymorphic datatype example to C++ examples

Added polymorphic_datatype_example() demonstrating:
- Creating type variables alpha and beta with Z3_mk_type_variable
- Defining parametric Pair datatype with fields of type alpha and beta
- Instantiating with concrete types (Pair Int Real) and (Pair Real Int)
- Getting constructors and accessors from instantiated datatypes
- Creating constants and expressions using the polymorphic types
- Verifying type correctness with equality (= (first p1) (second p2))

Fix finite_set sort cardinality computation for finite base sorts (#7997)
* Initial plan

* Implement cardinality computation for finite_set sorts

- Modified mk_sort in finite_set_decl_plugin.cpp to compute 2^|s| for finite base sorts
- If base sort size > 30, mark finite_set sort as very_big
- Added comprehensive tests to verify sort size calculations
- All tests pass successfully

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>

* Update finite_set_decl_plugin.cpp

* Fix unit tests for infinite base sorts

Updated test to check is_infinite() instead of is_very_big() for FiniteSet(Int) since infinite element sorts now result in infinite FiniteSet sorts (not very_big). Also updated comment to clarify the behavior.
