  34 <p>This page tracks which C defect reports are implemented within Clang.</p>
  35
  36 <p>The implementation status for defect reports against the C Standard are
  37 currently under investigation. Any defect report whose status in Clang is
  38 currently unknown will be marked in <span class="unknown">purple</span>.</p>

  40 <p>The <a href="https://github.com/llvm/llvm-project/issues/">LLVM bug tracker</a> uses
  41 the "c", "c99", "c11", "c17", and "c23" labels to track known bugs with Clang's language
