Here's the demonstration of the behavior change that `const` brings to the table: https://cuda.godbolt.org/z/h6e5Wb4PT It shows that adding `const` allows compiler to use the initializer values as written (it does not even bother instantiating `cxxx`), while without `const` it reads the array values, assuming that they may be changed externally. https://github.com/llvm/llvm-project/pull/110182 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
