2013-01-04Special case Recycler::clear(BumpPtrAllocator).Jakob Stoklund Olesen
A BumpPtrAllocator has an empty Deallocate() method, but Recycler::clear() would still call it for every single object ever allocated, bringing all those objects into cache. As a bonus, iplist::remove() will also write to the Prev/Next pointers on all the objects, so all those cache lines have to be written back to RAM before the pages are given back to the OS. Stop wasting time and memory bandwith by using the new clearAndLeakUnsafely() function to jettison all the recycled objects. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171541 91177308-0d34-0410-b5e6-96231b3b80d8
2013-01-04Add an iplist::clearAndLeakNodesUnsafely() function.Jakob Stoklund Olesen
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

2013-01-02Actually update the CMake and Makefile builds correctly, and update theChandler Carruth
code that includes Intrinsics.gen directly. This never showed up in my testing because the old Intrinsics.gen was still kicking around in the make build system and was correct there. =[ Thankfully, some of the bots to clean rebuilds and that caught this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171373 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

2012-12-31Remove the declspecs from small alignments that we can force withChandler Carruth
a union. These don't actually work for by-value function arguments, and MSVC warns if they exist even while (we hope) it aligns the argument correctly due to the other union member. This means MSVC will miss out on optimizations based on the alignment of the buffer, but really, there aren't that many for x86 and MSVC is likely not doing a great job of optimizing LLVM and Clang anyways. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171328 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
2012-12-31Start sketching out a roadmap for better subprocess management in theChandler Carruth
LLVM libraries. Also, clean up the doxygen and formatting of the existing interfaces. With this change I'm calling the existing interface "legacy" because I'd like to replace it with something much better. My end goal is to expose a common set of interfaces for inspecting various properties of a process, and implementations to expose those both for the current process and for child processes. This will also expose more rich interfaces for spawning and controling a subprocess, notably to use system calls like wait3 and wait4 where available and gather detailed resource usage stats about the subprocess. My plan (discussed with Michael Spencer on IRC) is to base this loosely around the proposed Boost.Process interface, but to implement a relatively small subset of that functionality based around the needs of LLVM, Clang, the Clang driver, etc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171285 91177308-0d34-0410-b5e6-96231b3b80d8
