Add some tests for the FileCheck utility. http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20121112/156007.html git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@168113 91177308-0d34-0410-b5e6-96231b3b80d8 2012-11-15 23:42:51 +00:00			`// RUN: FileCheck -input-file %s %s`

Fix a bug in FileCheck that wouldn't let define variables as follows: ; CHECK: [[VAR:[a-z]]] The problem was that to find the end of the regex var definition, it was simplistically looking for the next ]] and finding the incorrect one. A better approach is to count nesting of brackets (taking escaping into account). This way the brackets that are part of the regex can be discovered and skipped properly, and the ]] ending is detected in the right place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169109 91177308-0d34-0410-b5e6-96231b3b80d8 2012-12-02 16:02:41 +00:00			`; CHECK: op1 [[REG:r[0-9]]]`
