; RUN: not opt --foo |& grep {Unknown command line argument}

; there is no --foo
Test this differently: I saw this test fail because opt exited while llvm-as was still writing to the pipe, causing it to get a SIGPIPE. It seems best to change things to avoid the race altogether. llvm-svn: 54138 2008-07-29 03:09:01 +08:00			`; RUN: not opt --foo \|& grep {Unknown command line argument}`
Fix a bug that caused opt and other tools to silently ignore invalid command-line options. llvm-svn: 47523 2008-02-23 09:55:25 +08:00
