; RUN: not opt --foo 2>&1 | grep "Unknown command line argument"

; there is no --foo
Convert the uses of '\|&' to use '2>&1 \|' instead, which works on old versions of Bash. In addition, I can back out the change to the lit built-in shell test runner to support this. This should fix the majority of fallout on Darwin, but I suspect there will be a few straggling issues. llvm-svn: 159544 2012-07-03 02:37:59 +08:00			`; RUN: not opt --foo 2>&1 \| 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
