⚠️ C/C++ code formatter, clang-format found issues in your code. ⚠️

You can test this locally with the following command:

git-clang-format --diff origin/main HEAD --extensions c,cpp,h -- clang/include/clang/CIR/Analysis/CIRAnalysisKind.h clang/include/clang/CIR/Analysis/FallThroughWarning.h clang/lib/CIR/Analysis/CIRAnalysisKind.cpp clang/lib/CIR/Analysis/FallThroughWarning.cpp clang/test/CIR/Analysis/fallthrough_1.c clang/test/CIR/Analysis/fallthrough_2.c clang/include/clang/Frontend/FrontendOptions.h clang/lib/CIR/FrontendAction/CIRGenAction.cpp clang/lib/Sema/AnalysisBasedWarnings.cpp --diff_from_common_commit

The reproduction instructions above might return results for more than one PR
in a stack if you are using a stacked PR workflow. You can limit the results by
changing origin/main to the base branch/commit you want to compare against.
