REQUIRES: shell
RUN: ((false | true) && echo true || echo false) | grep false
Use pipefail when available. This change makes test with RUN lines like RUN: opt ... \| FileCheck fail if opt fails, even if it prints what FileCheck wants. Enabling this found some interesting cases of broken tests that were not being noticed because opt (or some other tool) was crashing late. Pipefail is used when the shell supports it or when using the internal python based tester. llvm-svn: 187261 2013-07-27 06:32:58 +08:00			`REQUIRES: shell`
