URL: https://github.com/llvm/llvm-project/commit/18b2385f2b09453b5e9d26459ec9e806f5ee7f86 DIFF: https://github.com/llvm/llvm-project/commit/18b2385f2b09453b5e9d26459ec9e806f5ee7f86.diff LOG: [clang] [test] Fix clang-cl unused argument tests on paths that start with /U This reinstates a test that was temporarily removed in e26bbae30218a35d76a79fe90b0e41dd0f71b779, in a form that works on Darwin. Use -LD instead of -link as a linker argument that is unused when compiling, that produces warnings normally. -LD can be placed anywhere in the command line, so that the command line ends with "-- %s", making paths starting with /U correctly interpreted as paths, not options.
