* Merge r168037 from trunk:Hans Wennborg2012-11-16
| | | | | | | | | | | | | | | | | Make GlobalOpt be conservative with TLS variables (PR14309) For global variables that get the same value stored into them everywhere, GlobalOpt will replace them with a constant. The problem is that a thread-local GlobalVariable looks like one value (the address of the TLS var), but is different between threads. This patch introduces Constant::isThreadDependent() which returns true for thread-local variables and constants which depend on them (e.g. a GEP into a thread-local array), and teaches GlobalOpt not to track such values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/branches/release_32@168192 91177308-0d34-0410-b5e6-96231b3b80d8

* Add method for replacing instructions to LibCallSimplifierMeador Inge2012-11-11
| | | | | | | | | | | | | | | In some cases the library call simplifier may need to replace instructions other than the library call being simplified. In those cases it may be necessary for clients of the simplifier to override how the replacements are actually done. As such, a new overrideable method for replacing instructions was added to LibCallSimplifier. A new subclass of LibCallSimplifier is also defined which overrides the instruction replacement method. This is because the instruction combiner defines its own replacement method which updates the worklist when instructions are replaced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167681 91177308-0d34-0410-b5e6-96231b3b80d8
* Add more functions to the target library information.Meador Inge2012-11-10
| | | | | | | | | | | In the process of migrating optimizations from the simplify-libcalls pass to the instcombine pass I noticed that a few functions are missing from the target library information. These functions need to be available for querying in the instcombine library call simplifiers. More functions will probably be added in the future as more simplifiers are migrated to instcombine. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167659 91177308-0d34-0410-b5e6-96231b3b80d8

* misched: Heuristics based on the machine model.Andrew Trick2012-11-07
| | | | | | | | | | | | | | misched is disabled by default. With -enable-misched, these heuristics balance the schedule to simultaneously avoid saturating processor resources, expose ILP, and minimize register pressure. I've been analyzing the performance of these heuristics on everything in the llvm test suite in addition to a few other benchmarks. I would like each heuristic check to be verified by a unit test, but I'm still trying to figure out the best way to do that. The heuristics are still in considerable flux, but as they are refined we should be rigorous about unit testing the improvements. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167527 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | This patch adds the interface to expose events from MCJIT when an object is emitted or freed and implements the MCJIT functionality to send those events.

* Add a method to indicate section address re-assignment is finished.Andrew Kaylor2012-11-05
| | | | | | Prior to this patch RuntimeDyld attempted to re-apply relocations every time reassignSectionAddress was called (via MCJIT::mapSectionAddress). In addition to being inefficient and redundant, this led to a problem when a section was temporarily moved too far away from another section with a relative relocation referencing the section being moved. To fix this, I'm adding a new method (finalizeObject) which the client can call to indicate that it is finished rearranging section addresses so the relocations can safely be applied. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167400 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix the IntegersSubsetTest unit test when compiled with gcc-4.7. The issue hereDuncan Sands2012-11-03
| | | | | | | | | | | | is that the unit test doesn't have IntTy equal to APInt, instead it uses a class derived from APInt. When, as in these lines, an IntTy& reference is returned but is assigned to an APInt&, the compiler destroys the temporary the IntTy& was referring to, leaving the APInt& referring to garbage. This causes the unittest to fail systematically on my machine; it can also be caught by running the test under valgrind. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167356 91177308-0d34-0410-b5e6-96231b3b80d8

* Add a getAddressSpace method to the GEP instruction to mirror that ofChandler Carruth2012-11-01
| | | | | | | | | | the inttoptr instruction. The conceptual model here is that 'getAddressSpace' refers to the address space of this instruction's type. It just happens that for GEPs, that is always the same as the pointer operand's address space.

* Revert the majority of the next patch in the address space series:Chandler Carruth2012-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167222 91177308-0d34-0410-b5e6-96231b3b80d8
* Revert the series of commits starting with r166578 which introduced theChandler Carruth2012-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | getIntPtrType support for multiple address spaces via a pointer type, and also introduced a crasher bug in the constant folder reported in PR14233. These commits also contained several problems that should really be addressed before they are re-committed. I have avoided reverting various cleanups to the DataLayout APIs that are reasonable to have moving forward in order to reduce the amount of churn, and minimize the number of commits that were reverted. I've also manually updated merge conflicts and manually arranged for the getIntPtrType function to stay in DataLayout and to be defined in a plausible way after this revert. Thanks to Duncan for working through this exact strategy with me, and Nick Lewycky for tracking down the really annoying crasher this triggered. (Test case to follow in its own commit.) After discussing with Duncan extensively, and based on a note from Micah, I'm going to continue to back out some more of the more problematic patches in this series in order to ensure we go into the LLVM 3.2 branch with a reasonable story here. I'll send a note to llvmdev explaining what's going on and why.
