* Rename the unittest from ArrayRecylerTest.cpp to ArrayRecyclerTest.cpp.Chandler Carruth2013-01-05

* Add an ArrayRecycler class.Jakob Stoklund Olesen2013-01-05
| | | | | | | | This is similar to the existing Recycler allocator, but instead of recycling individual objects from a BumpPtrAllocator, arrays of different sizes can be allocated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171581 91177308-0d34-0410-b5e6-96231b3b80d8
* Add time getters to the process interface for requesting the elapsedChandler Carruth2013-01-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | wall time, user time, and system time since a process started. For walltime, we currently use TimeValue's interface and a global initializer to compute a close approximation of total process runtime. For user time, this adds support for an somewhat more precise timing mechanism -- clock_gettime with the CLOCK_PROCESS_CPUTIME_ID clock selected. For system time, we have to do a full getrusage call to extract the system time from the OS. This is expensive but unavoidable. In passing, clean up the implementation of the old APIs and fix some latent bugs in the Windows code. This might have manifested on Windows ARM systems or other systems with strange 64-bit integer behavior. The old API for this both user time and system time simultaneously from a single getrusage call. While this results in fewer system calls, it also results in a lower precision user time and if only user time is desired, it introduces a higher overhead. It may be worthwhile to switch some of the pass timers to not track system time and directly track user and wall time. The old API also tracked walltime in a confusing way -- it just set it to the current walltime rather than providing any measure of wall time since the process started the way buth user and system time are tracked. The new API is more consistent here. The plan is to eventually implement these methods for a *child* process by using the wait3(2) system call to populate an rusage struct representing the whole subprocess execution. That way, after waiting on a child process its stats will become accurate and cheap to query. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171551 91177308-0d34-0410-b5e6-96231b3b80d8
* Add an iplist::clearAndLeakNodesUnsafely() function.Jakob Stoklund Olesen2013-01-04
| | | | | | | | | | | | The iplist::clear() function can be quite expensive because it traverses the entire list, calling deleteNode() and removeNodeFromList() on each element. If node destruction and deallocation can be handled some other way, clearAndLeakNodesUnsafely() can be used to jettison all nodes without bringing them into cache. The function name is meant to be ominous. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171540 91177308-0d34-0410-b5e6-96231b3b80d8

* Move all of the header files which are involved in modelling the LLVM IRChandler Carruth2013-01-02
| | | | | | | | | | | | | | | | | | | | | into their new header subdirectory: include/llvm/IR. This matches the directory structure of lib, and begins to correct a long standing point of file layout clutter in LLVM. There are still more header files to move here, but I wanted to handle them in separate commits to make tracking what files make sense at each layer easier. The only really questionable files here are the target intrinsic tablegen files. But that's a battle I'd rather not fight today. I've updated both CMake and Makefile build systems (I think, and my tests think, but I may have missed something). I've also re-sorted the includes throughout the project. I'll be committing updates to Clang, DragonEgg, and Polly momentarily. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171366 91177308-0d34-0410-b5e6-96231b3b80d8

* Begin sketching out the process interface.Chandler Carruth2012-12-31
| | | | | | | | | | | | | | | | | | | | | | | The coding style used here is not LLVM's style because this is modeled after a Boost interface and thus done in the style of a candidate C++ standard library interface. I'll probably end up proposing it as a standard C++ library if it proves to be reasonably portable and useful. This is just the most basic parts of the interface -- getting the process ID out of it. However, it helps sketch out some of the boiler plate such as the base class, derived class, shared code, and static factory function. It also introduces a unittest so that I can incrementally ensure this stuff works. However, I've not even compiled this code for Windows yet. I'll try to fix any Windows fallout from the bots, and if I can't fix it I'll revert and get someone on Windows to help out. There isn't a lot more that is mandatory, so soon I'll switch to just stubbing out the Windows side and get Michael Spencer to help with implementation as he can test it directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171289 91177308-0d34-0410-b5e6-96231b3b80d8

* Add an assertion for a likely ilist::splice() contract violation.Jakob Stoklund Olesen2012-12-18
| | | | | | | | | | | | | | | | | | | | | | | The single-element ilist::splice() function supports a noop move: List.splice(I, List, I); The corresponding std::list function doesn't allow that, so add a unit test to document that behavior. This also means that List.splice(I, List, F); is somewhat surprisingly not equivalent to List.splice(I, List, F, next(F)); This patch adds an assertion to catch the illegal case I == F above. Alternatively, we could make I == F a legal noop, but that would make ilist differ even more from std::list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@170443 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].
