I work on an out of tree backend and our customers requested the warning -Wformat-signedness to be implemented in clang (as they found it in gcc). I agree that the warning is pedantic. Note that gcc will with the options -Wformat and -pedantic enable at least the warnings related to scanf (see https://godbolt.org/z/WjzWKj89G). If you feel that the clang community don't really want -Wformat-signedness I can simply implement this in our downstream llvm-project repo and abandon this pull request. We already have a large number of diffs compared to https://github.com/llvm/llvm-project and a few more probably don't make any difference. https://github.com/llvm/llvm-project/pull/74440 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
