MaskRay added a comment. > This patch adds an example for -static-libcxx and -nostdlib.
We have -static-libstdc++ but not -static-libc++. (D53238 <https://reviews.llvm.org/D53238> attempts to add `-static` and name it `-static=c++stdlib`) > NoArgUnusedWith can be used for options which together are redundant or not > meaningful. I agree that `-Wunused-command-line-argument` sometimes gets in the way and removing the warnings is sometimes inconvenient. You can currently avoid the warning with: `--start-no-unused-arguments -static-libstdc++ --end-no-unused-arguments`. For `NoArgUnusedWith`, intuitively I am unsure whether it is sufficient for many options. For example, you probably want to remove the diagnostic with `-nostdlib++` and `-nodefaultlibs` as well. There are just so many similar options. ================ Comment at: clang/lib/Driver/Driver.cpp:4426 + std::function<bool(llvm::opt::DerivedArgList &, Arg *)> ConsideredUsed = + [&ConsideredUsed](llvm::opt::DerivedArgList &Args, Arg *A) { ---------------- Unless you want to capture it somewhere.
