2013-02-04Disable a couple more vector splat optimizations on PPC.Benjamin Kramer
I didn't see those because the test case used "not grep". FileCheck the test and XFAIL it, preserving the old optimization, so this can be fixed eventually. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174330 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04SelectionDAG: Teach FoldConstantArithmetic how to deal with vectors.Benjamin Kramer
This required disabling a PowerPC optimization that did the following: input: x = BUILD_VECTOR <i32 16, i32 16, i32 16, i32 16> lowered to: tmp = BUILD_VECTOR <i32 8, i32 8, i32 8, i32 8> x = ADD tmp, tmp The add now gets folded immediately and we're back at the BUILD_VECTOR we started from. I don't see a way to fix this currently so I left it disabled for now. Fix some trivially foldable X86 tests too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174325 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04Coding standards: don't use ``inline`` when defining a function in a classDmitri Gribenko
definition Current practice is not to use 'inline' in: class Foo { public: inline void bar() { // ... } }; git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174317 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-04Pass CPPFLAGS/CFLAGS/CXXFLAGS from the environment of configure toPatrik Hagglund
Makefile.config. This is implied at the bottom of the help text of configure (besides CC/CXX/LDFLAGS, already passed to Makefile.config). For backward compatibility, the values of CFLAGS and CXXFLAGS defaults to empty, overriding the default values provided by autoconf (for example, '-g -O2' when CC=gcc'). $(CPP) is not used by our makefiles. Therefore, the value of CPP is not passed to Makefile.config, despite beeing mentioned by 'configure --help'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174313 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-04More MSan/ASan annotations.Evgeniy Stepanov
This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains fixes for 2 issues: - X86JIT reads return address from stack, which MSan does not know is initialized. - bugpoint tests run binaries with RLIMIT_AS. This does not work with certain Sanitizers. We are no longer including config.h in Compiler.h with this change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174306 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-04ARM cost model: Penalize insertelement into D subregistersArnold Schwaighofer
Swift has a renaming dependency if we load into D subregisters. We don't have a way of distinguishing between insertelement operations of values from loads and other values. Therefore, we are pessimistic for now (The performance problem showed up in example 14 of gcc-loops). radar://13096933 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174300 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-04Turn off uninitialized-use warnings for gcc in cmake buildEdwin Vane
Added support to the cmake build to turn off uninitialized use warnings for gcc. This cleans the build up somewhat. Used logic simpler than found in autoconf by making use of the fact that although gcc won't complain about unsupported -Wno-* flags it *will* complain about unsupported -W flags.

2013-02-03Added instance variable/initializers/getter/setters for new keyword ↵Michael Gottesman
externally initialized to GlobalVariable. No *TRUE* functionality change. I am going to add in the actual test cases with the actual functionality changes in a later patch because I want to include some test cases. To be clear when I say no *TRUE* functionality change I mean that this patch (like it says in the title) only contains getters/setters and sets up a default initial value of the instance variable to false so that this patch does not affect any other uses of Global Variable.h. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174295 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-03[Object][Archive] Improve performance.Michael J. Spencer
Improve performance of iterating over children and accessing the member file buffer by caching the file size and moving code out to the header. This also makes getBuffer return a StringRef instead of a MemoryBuffer. Both fixing a memory leak and removing a malloc. This takes getBuffer from ~10% of the time in lld to unmeasurable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174272 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-03Added new Global Variable marker ``externally_initialized'' to LangRef.Michael Gottesman
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174270 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-03Added clarification paragraph to LangRef's documentation ofMichael Gottesman
GlobalVariable about LLVM's assumptions vis-a-vis Global Variable initial values and Global Variable initializers. This is in preparation for adding the new keyword externally_initialized. Specifically, the patch explains how LLVM optimizes global initializers by assumign that global variables defined within the module are not modified from their initial values before the start of the global initializer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174269 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-02Remove the (apparently) unnecessary debug info metadata indirection.David Blaikie
The main lists of debug info metadata attached to the compile_unit had an extra layer of metadata nodes they went through for no apparent reason. This patch removes that (& still passes just as much of the GDB 7.5 test suite). If anyone can show evidence as to why these extra metadata nodes are there I'm open to reverting this patch & documenting why they're there. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174266 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-02This patch makes "&Cls::purevfn" not an odr use. This isn't what the standardNick Lewycky
says, but that's a defect (to be filed). "Cls::purevfn()" is still an odr use. Also fixes a bug in the previous patch that caused us to not mark the function referenced just because we didn't want to mark it odr used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174240 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-01This patch aims to improve compile time performance by increasingPreston Gurd
the SCEV vector size in LoopStrengthReduce. It is observed that the BaseRegs vector size is 4 in most cases, and elements are frequently copied when it is initialized as SmallVector<const SCEV *, 2> BaseRegs. Our benchmark results show that the compilation time performance improved by ~0.5%.
