Motivation and Context

The project had an unnecessary dependency on Clang/LLVM for non-C/C++ analyses. This caused unintended behavior in environments where LLVM was not required, particularly in Linux distributions. The fix ensures that LLVM detection logic is applied only in Darwin environments and removes redundant checks on Linux.

How Has This Been Tested?

The following tests were conducted:

• Verified that the removal of LLVM detection does not affect non-C/C++ analyses.
• Added new test cases to confirm that Clang/LLVM dependency is no longer checked in Linux environments.
• Ensured that the detection logic remains intact for macOS (Darwin).
• Ran the full test suite to confirm no regressions.

Breaking Changes

No breaking changes. The fix only removes unnecessary logic and does not impact the core functionality.

Types of Changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

• My code follows the repository's style guidelines
• New and existing tests pass locally
• I have added appropriate error handling
• I have added or updated documentation as needed

Additional Context

• This change improves compatibility with Linux distributions where LLVM is not required.
• Helps streamline dependency management for non-C/C++ analyses.
• Ensures better separation of language-specific requirements.
