Add 'not' to commands that are expected to fail. This is at least good documentation, but also opens the possibility of using pipefail. llvm-svn: 185652 2013-07-04 16:16:58 +00:00			`// RUN: not %clang_cc1 -ferror-limit 1 -fsyntax-only %s 2>&1 \| FileCheck %s`
Fix -ferror-limit= to properly emit notes following the last error messages. Fi from David Blaikie, tests from Nikola Smiljanic! llvm-svn: 137851 2011-08-17 19:13:00 +00:00
