_umodsi3 libcalls if they have the same arguments. This optimization was apparently broken if one of the node was replaced in place. rdar://11714607 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158900 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-21Remove one of the LLVM-specific CMake hacks in favor of standard CMakeChandler Carruth
facilities. This was only used in one place in LLVM, and was used pervasively (but with different code!) in Clang. It has no advantages over the standard CMake facilities and in some cases disadvantages. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158889 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-21Update regunits in RegisterCoalescer::reMaterializeTrivialDef.Jakob Stoklund Olesen
Old code would only update physreg live intervals. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158881 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Remove LiveIntervals::iterator.Jakob Stoklund Olesen
Live intervals for regunits and virtual registers are stored separately, and physreg live intervals are going away. To visit the live ranges of all virtual registers, use this pattern instead: for (unsigned i = 0, e = MRI->getNumVirtRegs(); i != e; ++i) { unsigned Reg = TargetRegisterInfo::index2VirtReg(i); if (MRI->reg_nodbg_empty(Reg)) continue; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158879 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Remove the RenderMachineFunction HTML output pass.Jakob Stoklund Olesen
I don't think anyone has been using this functionality for a while, and it is getting in the way of refactoring now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158876 91177308-0d34-0410-b5e6-96231b3b80d8

Deterministically enumerate the virtual registers instead. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158872 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Remove LiveIntervalUnions from RegAllocBase.Jakob Stoklund Olesen
They are living in LiveRegMatrix now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158868 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Convert RAGreedy to LiveRegMatrix interference checking.Jakob Stoklund Olesen
Stop depending on the LiveIntervalUnions in RegAllocBase, they are about to be removed. The changes are mostly replacing register alias iterators with regunit iterators, and querying LiveRegMatrix instrad of RegAllocBase. InterferenceCache is converted to work with per-regunit LiveIntervalUnions, and it checks fixed regunit interference separately, using the fixed live intervals provided by LiveIntervalAnalysis. The local splitting helper calcGapWeights() is also considering fixed regunit interference which is kept on the side now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158867 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Convert RABasic to using LiveRegMatrix interference checking.Jakob Stoklund Olesen
Stop using the LiveIntervalUnions provided by RegAllocBase, they will be removed soon. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158866 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Enable register unit liveness by default.Jakob Stoklund Olesen
Soon we won't need to compute live intervals for physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158865 91177308-0d34-0410-b5e6-96231b3b80d8

Filter out physreg candidates with regunit interferrence. Also compute regmask interference more efficiently. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158864 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Avoid iterating with LiveIntervals::iterator.Jakob Stoklund Olesen
That is a DenseMap iterator keyed by pointers, so the iteration order is nondeterministic. I would like to replace the DenseMap with an IndexedMap which doesn't allow iteration. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158856 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Add "extern template" declarations now that we use explicit instantiation.Andrew Trick
This is supported by gcc and clang, but guarded by a macro for MSVC 2008. The extern template declaration is not necessary but generally good form. It can avoid extra instantiations of the template methods defined inline. The EXTERN_TEMPLATE_INSTANTIATION macro could probably be generalized to handle multiple template parameters if someone thinks it's worthwhile. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158840 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Only update regunit live ranges that have been precomputed.Jakob Stoklund Olesen
Regunit live ranges are computed on demand, so when mi-sched calls handleMove, some regunits may not have live ranges yet. That makes updating them easier: Just skip the non-existing ranges. They will be computed correctly from the rescheduled machine code when they are needed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158831 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20replace usage of EmitGEPOffset() with TargetData::getIndexedOffset() when ↵Nuno Lopes
the GEP offset is known to be constant. With this change, we avoid relying on the IR Builder to constant fold the operations. No functionality change intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158829 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-20Remove 'static' from inline functions defined in header files.Chandler Carruth
There is a pretty staggering amount of this in LLVM's header files, this is not all of the instances I'm afraid. These include all of the functions that (in my build) are used by a non-static inline (or external) function. Specifically, these issues were caught by the new '-Winternal-linkage-in-inline' warning. I'll try to just clean up the remainder of the clearly redundant "static inline" cases on functions (not methods!) defined within headers if I can do so in a reliable way. There were even several cases of a missing 'inline' altogether, or my personal favorite "static bool inline". Go figure. ;] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158800 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Fix two rather subtle internal vs. external linker issues.Chandler Carruth
I'll admit I'm not entirely satisfied with this change, but it seemed the cleanest option. Other suggestions quite welcome The issue is that the traits specializations have static methods which return the typedef'ed PHI_iterator type. In both the IR and MI layers this is typedef'ed to a custom iterator class defined in an anonymous namespace giving the types and the functions returning them internal linkage. However, because the traits specialization is defined in the 'llvm' namespace (where it has to be, specialized template lives there), and is in turn used in the templated implementation of the SSAUpdater. This led to the linkage conflict that Clang now warns about. The simplest solution to me was just to define the PHI_iterator as a nested class inside the trait specialization. That way it still doesn't get scoped widely, it can't be accidentally reused somewhere, etc. This is a little gross just because nested class definitions are a little gross, but the alternatives seem more ad-hoc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158799 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-20Fix inappropriate use of anonymous namespaces in unittests.Chandler Carruth
The TEST_F macros actually declare *subclasses* of the test fixtures. Even if they didn't we don't want them to declare external functions. The entire unit test, including both the fixture class and the fixture test cases should be wrapped in the anonymous namespace. This issue was caught by the new '-Winternal-linkage-in-inline' warning. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158798 91177308-0d34-0410-b5e6-96231b3b80d8
