Maybe your search logic for hidden options has bugs, but I didn't dive into it to check. > 1.

Are you sure you're testing everything right? You have an up-to-date clang build for example? The testing tool should give you an output like `llvm-lit: (...)/llvm/utils/lit/lit/llvm/config.py:506: note: using clang (...)/build/bin/clang` that should be pointing into the llvm build folder. https://github.com/llvm/llvm-project/pull/120900 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
