Add commands:
(prefer <formula>)
- will instruct case split queue to assign formula to true.
- prefer commands added within a scope are forgotten after leaving the scope.
(reset-preferences)
- resets asserted preferences. Has to be invoked at base level.
This provides functionality related to MathSAT and based on an ask by Tomáš Kolárik who is integrating the functionality with OpenSMT2
* Add comprehensive API special relations tests
- Implement tests for all 5 special relations API functions:
* Z3_mk_linear_order - Linear order relation

- Test coverage achieved: 100% (5/5 lines) in src/api/api_special_relations.cpp
- Added comprehensive test cases covering:
* Basic functionality with different sorts
* Different index parameters
* Expression creation and integration
* Edge cases and variations

This commit addresses issue #6651 by adding macOS-specific CMake configuration
to ensure proper .dylib versioning in pip packages.
Problem:
- .dylib files distributed in pip packages showed version 0.0.0 instead of the
actual Z3 version when inspected with otool -L on macOS
- This created compatibility issues and made it difficult to manage library dependencies
Solution:
- Added macOS-specific CMake properties to the libz3 target
- Set INSTALL_NAME_DIR to '@rpath' for better library relocatability
- Enabled MACOSX_RPATH to ensure proper RPATH handling
- Existing VERSION and SOVERSION properties handle compatibility/current version automatically
The fix ensures that macOS .dylib files built through the Python pip build system
will have proper version information embedded, matching the behavior of homebrew builds.

Added comprehensive test coverage for Z3's pseudo-boolean constraint API functions, improving coverage from 0% to 100% for src/api/api_pb.cpp.
- Created comprehensive test suite in src/test/api_pb.cpp
- Added test registration in src/test/main.cpp and src/test/CMakeLists.txt
- Implemented tests for all 5 API functions:
* Z3_mk_atmost: at most k variables can be true
* Z3_mk_atleast: at least k variables can be true
* Z3_mk_pble: weighted pseudo-boolean less-than-or-equal constraint
* Z3_mk_pbge: weighted pseudo-boolean greater-than-or-equal constraint
* Z3_mk_pbeq: weighted pseudo-boolean equality constraint
- Comprehensive test cases covering edge cases, negative coefficients, zero thresholds, empty arrays, and complex scenarios
- All tests pass successfully with 100% coverage achieved
Coverage improvement: api_pb.cpp went from 0% (0/64 lines) to 100% (64/64 lines)

This addresses issue #1163 by removing the #ifdef _WINDOWS guard from
src/test/hashtable.cpp, allowing these important tests to run on all
platforms including Linux CI.
Key changes:
- Removed #ifdef _WINDOWS preprocessor guard
- Removed corresponding #else/#endif block
- Tests now compile and run on all platforms
This is part of the broader unit test modernization effort to ensure
comprehensive cross-platform test coverage.

This implements the enhancement requested in #1441, providing a
clang-format configuration file that matches Z3's existing C++ style.
Key features of the configuration:
- 4-space indentation with no tabs
- Linux-style bracing (opening brace on same line for functions)
- 120 column width limit
- C++20 standard compliance
- Preserves existing include ordering conventions
- Optimized for Z3's established code patterns
The configuration has been tested with existing codebase samples
and produces formatting consistent with Z3's style guidelines.

This change addresses issue #1664 by implementing an include directory that
consolidates all Z3 API headers in one convenient location for developers.
## Implementation
- Creates `build/include/` directory during CMake configuration
- Copies all Z3 API headers (z3*.h) and C++ API header (z3++.h) to include directory
- Updates libz3 target to expose the include directory via target_include_directories
- Uses CMake custom target with POST_BUILD commands for automatic header copying
## Benefits
- **Developer Experience**: Single include directory eliminates need to specify multiple paths
- **Build Integration**: Works seamlessly with existing CMake build system
- **API Completeness**: Includes both C API and C++ API headers
- **Automatic Updates**: Headers are copied automatically during build process
## Usage
Developers can now:
- Use `-I build/include` for manual compilation
- Benefit from automatic include path setup when using Z3 via CMake find_package()
- Access all Z3 API headers from a single, predictable location
This follows the standard C/C++ project convention of having a dedicated include
directory, making Z3 easier to integrate into external projects.
