CHECK: unknown option e.

llvm-ar: exit with 1 if there is an error. This is pr34396. llvm-svn: 312752 2017-09-08 06:20:38 +08:00			`Test that llvm-ar exits with 1 when there is an error.`

			`RUN: not llvm-ar e 2>&1 \| FileCheck %s`
			`CHECK: unknown option e.`
Don't call exit from cl::PrintHelpMessage. Most callers were not expecting the exit(0) and trying to exit with a different value. This also adds back the call to cl::PrintHelpMessage in llvm-ar. llvm-svn: 312761 2017-09-08 07:30:48 +08:00			`CHECK: OVERVIEW: LLVM Archiver (llvm-ar)`
