[Driver] Prevent no-arc-exception-silence.m test from writing output. Summary: This enables the test to run on systems where output cannot be written. Reviewers: compnerd Subscribers: cfe-commits Differential Revision: https://reviews.llvm.org/D29123 llvm-svn: 293051 2017-01-25 20:55:53 +08:00			`// RUN: %clang -Werror -fobjc-arc -fobjc-arc-exceptions -fno-objc-arc -Xclang -verify -c -o /dev/null %s`
Driver: ignore -fno-objc-arc-exception when -fno-objc-arc set Sometime clang would be supplied -fobjc-arc -f(no)objc-arc-exceptions and then later disable ARC with -fno-objc-arc, which only negate first option, but not the latter, resulting usused argument warning. Silence this warning only when -fno-objc-arc option is present. Patch by Onha Choe! llvm-svn: 293014 2017-01-25 11:36:28 +08:00			`// expected-no-diagnostics`
