Clang Static Analyzer

Purpose: Clang Static Analyzer finds bugs in C, C++ and Objective-C programs.
Analysis method: It implements path-sensitive, inter-procedural analysis based on symbolic execution.
Open source: The analyzer is 100% open source and part of the Clang project.
Library: The analyzer is implemented as a reusable C++ library for other tools and applications.
Command line: Official releases include scan-build, a command-line tool for running the analyzer on a codebase.
Xcode integration: On macOS, the easiest way to use the analyzer is to invoke it directly from Xcode.
clang-tidy integration: The analyzer can run alongside clang-tidy by enabling clang-analyzer checks.
IDE integration: An IDE using Clang may natively integrate the static analyzer.
Additional tooling: The documentation provides command-line usage guidance for scan-build and CodeChecker.
Performance limitation: Static analysis can be much slower than compilation and some algorithms require exponential time in the worst case.
False positives: The analyzer can falsely flag bugs in code that behaves correctly, with frequency varying by check.
Scope limitation: The analyzer can only find bugs it has been specifically engineered to find.
License: Current LLVM releases are distributed under the Apache-2.0 with LLVM-exception license.
Release verification: LLVM says source packages and git tags are signed by release managers and provides GnuPG keys for verification.
