| // 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) | 
 |  | 
 | // 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: argument unused during compilation | 
 | // Identify the linker command | 
 | // ARGS: link.exe |
