* Make llvm::Regex non-copyable but movable.David Blaikie2014-01-02
| | | | | | Based on a patch by Maciej Piechotka. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198334 91177308-0d34-0410-b5e6-96231b3b80d8
* Swap around EXPECT_EQ() arguments orders for more natural gtest Failure messagesAlp Toker2013-12-12
| | | | | | | | | Somewhat counterintuitively the first arg in gtest is treated as the expectation. No change to the tests themselves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197124 91177308-0d34-0410-b5e6-96231b3b80d8
* Add missing escape characters to the new Regex::escape() functionAlp Toker2013-12-12
| | | | | | | | | The old AddFixedStringToRegEx() it was based on got away with this for the longest time, but the problem became easy to spot after the cleanup in r197096. Also add a quick unit test to cover regex escaping. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197121 91177308-0d34-0410-b5e6-96231b3b80d8

* Introduce Regex::isLiteralERE function.Peter Collingbourne2013-08-05
| | | | | | | | | This will be used to implement an optimisation for literal entries in special case lists. Differential Revision: http://llvm-reviews.chandlerc.com/D1278 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@187731 91177308-0d34-0410-b5e6-96231b3b80d8

* Add backreference matching capabilities to Support/Regex, withEli Bendersky2012-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | appropriate unit tests. This change in itself is not expected to affect any functionality at this point, but it will serve as a stepping stone to improve FileCheck's variable matching capabilities. Luckily, our regex implementation already supports backreferences, although a bit of hacking is required to enable it. It supports both Basic Regular Expressions (BREs) and Extended Regular Expressions (EREs), without supporting backrefs for EREs, following POSIX strictly in this respect. And EREs is what we actually use (rightly). This is contrary to many implementations (including the default on Linux) of POSIX regexes, that do allow backrefs in EREs. Adding backref support to our EREs is a very simple change in the regcomp parsing code. I fail to think of significant cases where it would clash with existing things, and can bring more versatility to the regexes we write. There's always the danger of a backref in a specially crafted regex causing exponential matching times, but since we mainly use them for testing purposes I don't think it's a big problem. [it can also be placed behind a flag specific to FileCheck, if needed].
