2013-01-05Eric thought that Darwin was right to use -1 consistently rather thanChandler Carruth
leaving this undefined, and despite the sentence in the standard that seems to require it, I'll cede the point and assume its a bug in the wording. Other parts of POSIX regularly allow for things to be -1 instead of undefined, this should too. Makes things more consistent too. This should have to real impact for folks though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171574 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-05Try to suppress the use of clock_gettime on Darwin which apparantlyChandler Carruth
defines _POSIX_CPUTIME but doesn't support the clock_* functions. I don't test the value of _POSIX_CPUTIME because the spec merely says that if it is defined, the CPU-specific timers are available, whereas it says that _POSIX_TIMERS must be defined and defined to a value greater than zero. However, this may not work, as the POSIX spec clearly states: "If the symbolic constant _POSIX_CPUTIME is defined, then the symbolic constant _POSIX_TIMERS shall also be defined by the implementation to have the value 200112L." If this doesn't work, I'll add more hacks for Darwin. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171565 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171559 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-04Add time getters to the process interface for requesting the elapsedChandler Carruth
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

2013-01-02Move all of the header files which are involved in modelling the LLVM IRChandler Carruth
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

2012-12-31Begin sketching out the process interface.Chandler Carruth
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

2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

2012-11-28Add backreference matching capabilities to Support/Regex, withEli Bendersky
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].
