+// PR17239 - The /link option, when inside a response file, should only extend
+// until the end of the response file (and not the entire command line)
+
+// Don't attempt slash switches on msys bash.
+// REQUIRES: shell-preserves-root
+
+// Note: %s must be preceded by -- or bound to another option, otherwise it may
+// be interpreted as a command-line option, e.g. on Mac where %s is commonly
+// under /Users.
+
+// RUN: echo /link bar.lib baz.lib > %t.args
+// RUN: touch %t.obj
+// RUN: %clang_cl -### @%t.args -- %t.obj 2>&1 | FileCheck %s -check-prefix=ARGS
+// If the "/link" option captures all remaining args beyond its response file,
+// it will also capture "--" and our input argument. In this case, Clang will
+// be clueless and will emit "argument unused" warnings. If PR17239 is properly
+// fixed, this should not happen because the "/link" option is restricted to
+// consume only remaining args in its response file.
+// ARGS-NOT: warning
+// ARGS-NOT: argument unused during compilation
+// Identify the linker command
+// ARGS: link.exe
