* Go ahead and get rid of the old page size interface and convert all theChandler Carruth2012-12-314-19/+11
| | | | | | | users over to the new one. No sense maintaining this "compatibility" layer it seems. llvm-svn: 171331
* Flesh out a page size accessor in the new API.Chandler Carruth2012-12-313-12/+21
| | | | | | | | Implement the old API in terms of the new one. This simplifies the implementation on Windows which can now re-use the self_process's once initialization. llvm-svn: 171330

* reimplement GetPointerBaseWithConstantOffset().Nuno Lopes2012-12-311-31/+21
| | | | | | | The new code is an improved copy of the code I deleted from Analysis/Loads.cpp. One less compute-constant-gep-offset implementation. yay :) llvm-svn: 171326

* Switch this code to a more idiomatic double using namespace directive.Chandler Carruth2012-12-313-6/+3
| | | | | | | | 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. llvm-svn: 171292

* Begin sketching out the process interface.Chandler Carruth2012-12-313-1/+33
| | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 171289

* convert a bunch of callers from DataLayout::getIndexedOffset() to ↵Nuno Lopes2012-12-308-83/+30
| | | | | | | | | GEP::accumulateConstantOffset(). The later API is nicer than the former, and is correct regarding wrap-around offsets (if anyone cares). There are a few more places left with duplicated code, which I'll remove soon. llvm-svn: 171259

* LoopVectorizer: Fix a bug in the code that updates the loop exiting block.Nadav Rotem2012-12-301-0/+13
| | | | | | | | | 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. PR14725 llvm-svn: 171251
* Add a few more c'tors:Bill Wendling2012-12-302-5/+29
| | | | | | | | | | | | | | | * One that accepts a single Attribute::AttrKind. * One that accepts an Attribute::AttrKind plus a list of values. This is for attributes defined like this: #1 = attributes { align = 4 } * One that accepts a string, for target-specific attributes like this: #2 = attributes { "cpu=cortex-a8" } llvm-svn: 171249
* Add a few (as yet unused) query methods to determine if the attribute that'sBill Wendling2012-12-302-0/+31

* Fix a stunning oversight in the inline cost analysis. It was neverChandler Carruth2012-12-281-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 171196
* Teach the inline cost analysis about calls that can be simplified andChandler Carruth2012-12-281-11/+87
| | | | | | | | | | | | | | | | | | | | | 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. llvm-svn: 171195
* Teach instsimplify to use the constant folder where appropriate forChandler Carruth2012-12-281-8/+29
| | | | | | | | 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. llvm-svn: 171194
* Add entry points to instsimplify for simplifying calls. The entry pointsChandler Carruth2012-12-281-5/+30
| | | | | | | | | | 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. llvm-svn: 171189
