2012-12-31Switch this code to a more idiomatic double using namespace directive.Chandler Carruth
Fix a truly odd namespace qualifier that was flat out wrong in the process. The fully qualified namespace would have been llvm::sys::TimeValue, llvm::TimeValue makes no sense. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171292 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

2012-12-30LoopVectorizer: Fix a bug in the code that updates the loop exiting block.Nadav Rotem
LCSSA PHIs may have undef values. The vectorizer updates values that are used by outside users such as PHIs. The bug happened because undefs are not loop values. This patch handles these PHIs.

2012-12-28Nuke some dead code that snuck in some how. I thought I had alreadyChandler Carruth
deleted this, but apparantly not. Charmingly, Clang didn't warn on it but GCC did. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171197 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-28Fix a stunning oversight in the inline cost analysis. It was neverChandler Carruth
propagating one of the values it simplified to a constant across a myriad of instructions. Notably, ptrtoint instructions when we had a constant pointer (say, 0) didn't propagate that, blocking a massive number of down-stream optimizations. This was uncovered when investigating why we fail to inline and delete the boilerplate in: void f() { std::vector<int> v; v.push_back(1); } It turns out most of the efforts I've made thus far to improve the analysis weren't making it far purely because of this. After this is fixed, the store-to-load forwarding patch enables LLVM to optimize the above to an empty function. We still can't nuke a second push_back, but for different reasons. There is a very real chance this will cause somewhat noticable changes in inlining behavior, so please let me know if you see regressions (or improvements!) because of this patch. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171196 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-28Teach the inline cost analysis about calls that can be simplified andChandler Carruth
how to propagate constants through insert and extract value instructions. With the recent improvements to instsimplify, this allows inline cost analysis to constant fold through intrinsic functions, including notably the with.overflow intrinsic math routines which often show up inside of STL abstractions. This is yet another piece in the puzzle of breaking down the code for: void f() { std::vector<int> v; v.push_back(1); } But it still isn't enough. There are a pile of bugs in inline cost still blocking this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171195 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-28Teach instsimplify to use the constant folder where appropriate forChandler Carruth
constant folding calls. Add the initial tests for this which show that now instsimplify can simplify blindingly obvious code patterns expressed with both intrinsics and library calls. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171194 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-28Add entry points to instsimplify for simplifying calls. The entry pointsChandler Carruth
are nice and decomposed so that we can simplify synthesized calls as easily as actually call instructions. The internal utility still has the same behavior, it just now operates on a more generic interface so that I can extend the set of call simplifications that instsimplify knows about. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@171189 91177308-0d34-0410-b5e6-96231b3b80d8
