* Verify that macho-o delta64 relocs have the same offset.Pete Cooper2015-12-103-21/+115
| | | | | | | | | | The delta64 relocation is represented as the pair ARM64_RELOC_SUBTRACTOR and ARM64_RELOC_UNSIGNED. Those should always have the same offset, so this adds a check and tests to ensure this is the case. Also updated the error printing in this case to shows both relocs when erroring on pair. llvm-svn: 255274
* libclang: expose dllexport, dllimport attributesSaleem Abdulrasool2015-12-106-2/+79
| | | | | | | These attributes were previously unexposed. Expose them through the libclang interfaces. Add tests that cover both the MSVC spelling and the GNU spelling. llvm-svn: 255273

* [PGO] Use %t as the temporary profdata filename in the test cases.Rong Xu2015-12-1010-19/+19
| | | | | | Using %t rather %T/<specific_name> as the temporary profdata filename. llvm-svn: 255271
* [PGO] Header file cleanup (NFC)Xinliang David Li2015-12-102-41/+55
| | | | | | | | | InstrProfiling.h file declares profile runtime public APIs. It has become a dumping place for many different things, which needs cleanups. In this change, core type declarations and portability macros are moved to a new file InstrProfilingPort.h. llvm-svn: 255270
* Verifier: Avoid quadratic checking of aggregates for bad bitcastsDuncan P. N. Exon Smith2015-12-101-38/+37
| | | | | | | | | | | | | | | | | | | | | | | Avoid O(N^2) behaviour when checking for bad bitcasts in `ConstantExpr`s buried inside of aggregate initializers to `GlobalVariable`s. I've: - centralized the "visited" set for recursing through `ConstantExpr`s so that expressions are only visited once per Verifier run, - removed the duplicate logic for the stack visit, and - avoided recursing into other `GlobalValue`s. This recovers roughly a 100x time difference in clang compiles of a particular input file (filled with large cross-referencing tables) that depends on whether `-disable-llvm-verifier` is on. This slowdown was caused by r187506, which introduced these checks. Now, avoiding `-disable-llvm-verifier` only causes a 2x slowdown for this case. (Interestingly, dumping the textual IR for this file starts at least 50GB of global variable initializers (I don't know the total, since I killed the dump)...) llvm-svn: 255269
* Add Hexagon ABI to System InitializationTed Woodward2015-12-101-0/+3
| | | | | | | | | | | | Summary: When the Hexagon ABI was added, it was inadvertently left out of initialization/termination. This patch adds it. Reviewers: clayborg Subscribers: lldb-commits Differential Revision: http://reviews.llvm.org/D15347 llvm-svn: 255268
* [Modules] Fix regression when an elaborated-type-specifier mentions a hidden tagBen Langmuir2015-12-104-4/+34

* [ProfileData] Add unit test infrastructure for sample profile reader/writerNathan Slingerland2015-12-106-23/+187
| | | | | | | | | | | | | | | Summary: Adds support for in-memory round-trip of sample profile data along with basic round trip unit tests. This will also make it easier to include unit tests for future changes to sample profiling.

* [InstCombine] fold bitcasts around an extractelement (3rd try)Sanjay Patel2015-12-102-8/+73
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a redo of r255137 (reverted at r255227) which was a redo of r255124 (reverted at r255126) with a fixed check for a scalar source type and an added test for the failure that caused the revert. Original commit message: Example: bitcast (extractelement (bitcast <2 x float> %X to <2 x i32>), 1) to float ---> extractelement <2 x float> %X, i32 1 This is part of fixing PR25543: https://llvm.org/bugs/show_bug.cgi?id=25543 The next step will be to generalize this fold: trunc ( lshr ( bitcast X) ) -> extractelement (X) Ie, I'm hoping to replace the existing transform of: bitcast ( trunc ( lshr ( bitcast X))) added by: http://reviews.llvm.org/rL112232 with 2 less specific transforms to catch the case in the bug report.

* Add modules downloaded by ModuleCache to the global ModuleListTamas Berghammer2015-12-101-5/+11
| | | | | | | | | | | | | Adding the modules to the global module list eleminate issues in the case when a module is unloaded from the target but some object (e.g. breakpoint) still referencing them with weak pointers. It also speeds up the case when we load, unload, load the same shared library because the global module cache will keep the parsed debug info around between the 2 load (this scenario happens for some code on android).

* [ThinLTO] Debug message cleanup (NFC)Teresa Johnson2015-12-101-8/+8
| | | | | | | | Added some missing spaces between the module identifier and the start of the debug message. Also added a ":" after the module identifier to make this look a little nicer. llvm-svn: 255259

* Slit lib/Linker in two.Rafael Espindola2015-12-109-1483/+1718
| | | | | | | | | | | | | | | | A linker normally has two stages: symbol resolution and "moving stuff". In lib/Linker there is the complication of lazy linking some globals, but it was still far more mixed than it needed to. This splits the linker into a lower level IRMover and the linker proper. The IRMover just takes a list of globals to move and a callback that lets the user control what is lazy linked. The main motivation is that now tools/gold (and soon lld) can use their own symbol resolution to instruct IRMover what to do. llvm-svn: 255254

* [DeadStoreElimination] Add support for non-local DSE.Chad Rosier2015-12-106-90/+393
| | | | | | | | | | | | We extend the search for redundant stores to predecessor blocks that unconditionally lead to the block BB with the current store instruction. That also includes single-block loops that unconditionally lead to BB, and if-then-else blocks where then- and else-blocks unconditionally lead to BB. http://reviews.llvm.org/D13363 Patch by Ivan Baev <ibaev@codeaurora.org>! llvm-svn: 255247
* Bitcasts between FP and INT values using direct movesNemanja Ivanovic2015-12-103-92/+334
| | | | | | | | | | | | This patch corresponds to review: http://reviews.llvm.org/D15286 LLVM IR frequently contains bitcast operations between floating point and integer values of the same width. Doing this through memory operations is quite expensive on PPC. This patch allows the use of direct register moves between FPRs and GPRs for lowering bitcasts. llvm-svn: 255246
* Macro debug info support in LLVM IRAmjad Aboud2015-12-1020-40/+509

* [clang-tidy] Sort includes case-sensitively.Alexander Kornienko2015-12-101-4/+1
| | | | | | | | | The motivation is: 1. consistency with clang-format, vim :sort etc. 2. we don't want the tools to depend on the current locale to do the include sorting llvm-svn: 255243
* [asan] Use atomic_uintptr_t instead of atomic_uint64_t in SuppressErrorReport.Yury Gribov2015-12-101-2/+2
| | | | | | | | | Some targets (e.g. Mips) don't have 64-bit atomics, so using atomic_uint64_t leads to build failures. Use atomic_uintptr_t to avoid such errors. Patch by Max Ostapenko. llvm-svn: 255242
* [LLE] Use the PredicatedScalarEvolution interface to query SCEVs for dependencesSilviu Baranga2015-12-101-16/+15
| | | | | | | | | | | | | | | | | Summary: LAA uses the PredicatedScalarEvolution interface, so it can produce forward/backward dependences having SCEVs that are AddRecExprs only after being transformed by PredicatedScalarEvolution. Use PredicatedScalarEvolution to get the expected expressions. Reviewers: anemet Subscribers: llvm-commits, sanjoy Differential Revision: http://reviews.llvm.org/D15382 llvm-svn: 255241
* Switch to gold linker on android x86, x86_64, armTamas Berghammer2015-12-101-0/+7
| | | | | | | | | | | | These architectures already using the gold linker for the android framework and switching to gold gives us the opportunity to enable ICF. Safe ICF (identical code folding) reduces the size of an optimized and striped binary by ~5%. Differential revision: http://reviews.llvm.org/D15379 llvm-svn: 255240
* [RenderScript] Refactor condition deciding when to JIT RS runtimeEwan Crawford2015-12-101-9/+19
| | | | | | | Patch creates a member function that decides when to JIT all the details about an allocation. By checking for zero pointers we can avoid the situation where we store uninitialised data from previously inspecting the allocation during creation. llvm-svn: 255238

* [analyzer] Fix symbolic element index lifetime.Artem Dergachev2015-12-108-7/+189
| | | | | | | | | | | | SymbolReaper was destroying the symbol too early when it was referenced only from an index SVal of a live ElementRegion. In order to test certain aspects of this patch, extend the debug.ExprInspection checker to allow testing SymbolReaper in a direct manner. Differential Revision: http://reviews.llvm.org/D12726 llvm-svn: 255236
* [ELF] - Implemented --print-gc-sections command line argument.George Rimar2015-12-105-1/+41

* [PostRA scheduling] Allow a target to do scheduling when it wants post RA.Jonas Paulsson2015-12-104-5/+29
| | | | | | | | | | | | | | SystemZ needs to do its scheduling after branch relaxation, which can only happen after block placement, and therefore the standard PostRAScheduler point in the pass sequence is too early. TargetMachine::targetSchedulesPostRAScheduling() is a new method that signals on returning true that target will insert the final scheduling pass on its own. Reviewed by Hal Finkel llvm-svn: 255234
* [ELF] - Resolve R_386_PLT32 statically in some cases.George Rimar2015-12-102-35/+51
| | | | | | | | | If R_386_PLT32 relocation is applied against symbol that can not be preempted then it can be resolved statically. Patch implements it for x86 target. Differential revision: http://reviews.llvm.org/D15376 llvm-svn: 255233
