Clang Static Analyzer features and specs

  • Integration with Clang
    The Clang Static Analyzer is built as part of the Clang project, ensuring seamless integration with the Clang compiler. This allows for easy adoption in projects that already use Clang for compiling, as there is no need for additional tooling setup.
  • Open Source
    Being an open-source tool, Clang Static Analyzer is freely available for anyone to use and modify. This encourages a community-driven approach to improvements and provides the flexibility to tailor the tool to specific needs.
  • Path-sensitive Analysis
    Clang Static Analyzer performs path-sensitive analysis, which means it evaluates different execution paths in the code to detect complex bugs that may only manifest under certain conditions.
  • Deep C/C++ Support
    As part of the LLVM project, Clang Static Analyzer offers robust support for C and C++ languages, leveraging the deep language understanding from the Clang front-end.

Possible disadvantages of Clang Static Analyzer

  • Limited Language Support
    While it is excellent for C and C++, Clang Static Analyzer has limited support for other programming languages, which can be a drawback for projects involving multiple languages.
  • False Positives
    Like many static analysis tools, Clang Static Analyzer can generate false positives, where it reports issues that are not actual bugs. This can require developers to spend additional time reviewing and dismissing spurious warnings.
  • Complex Setup for Non-Clang Projects
    Projects that are not already using Clang might face a more complex setup process to integrate Clang Static Analyzer, as it requires adapting build configurations to use Clang.
  • Performance Overhead
    Running Clang Static Analyzer can introduce significant performance overhead during the analysis phase, which might lead to longer build or integration times, especially for large codebases.

  • Improvements to static analysis in GCC 14
    Clang has a similar tool, the Clang Static Analyzer: https://clang-analyzer.llvm.org/. - Source: Hacker News / about 1 year ago
  • Memory Safe or Bust?
    Continuous Integration and Continuous Deployment [CI/CD] pipelines play a crucial role in enforcing code quality, especially when working with memory-unsafe languages. By integrating automated dynamic analysis tools like Valgrind or AddressSanitizer, static analysis tools like Clang Static Analyzer or cppcheck, and manual code review processes, developers can identify and mitigate many memory-related... - Source: dev.to / about 1 year ago
  • Static Code analysis
    No one static analyzer catches everything. It's best to run multiple. Popular ones are cppcheck, clang-analyzer, GCC static analyzer in GCC 10+, flawfinder, lizard. Source: about 2 years ago
  • Checked C
    With "cross translation units" (CTU) analysis a static analyzer could derive a constraint on `some_function` return value and check this against the array size to detect a possible bug. The Clang static analyzer [1], used through CodeChecker (CC) [2], do support CTU (enabled with `--ctu`). I'm very happy with the result on the code I'm working on. Of course this is not magic, and it's important to understand the... - Source: Hacker News / over 2 years ago
  • What's in your tool belt?
    Cppcheck and Clang Analyzer: statically analyze your code to find bad style and bugs (undefined behavior) respectively. Clang Analyzer can actually be frighteningly clever and has a low false positive rate (unlike most other non-commercial static checkers). Source: almost 3 years ago
