The statement "Clang assumes the host triple" is an approximation. clang's default target is specified by the LLVM_DEFAULT_TARGET_TRIPLE CMake flag. By default, that's the host triple, but you can override it. If you need some specific set of "libc" headers, you can mock them in clang/test/Headers/Inputs/ . https://github.com/llvm/llvm-project/pull/149176 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
