* [MS ABI] Don't rely on terminatepadDavid Majnemer2015-12-141-7/+6
| | | | | | | | | | | | | | | We'd like to remove support for terminatepad from LLVM. To do this, we need to move Clang off of it first. The intent behind terminatepad was to carefully model exception specifications for the MSVC personality. However, we don't support exception specifications for the MSVC personality and neither does MSVC. Instead, MSVC supports all-or-nothing exception specifications. We can model this limited usage using cleanuppads which call std::terminate. Differential Revision: http://reviews.llvm.org/D15478 llvm-svn: 255521

* [ThinLTO] Option to invoke ThinLTO backend passes and importingTeresa Johnson2015-12-072-53/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Adds new option -fthinlto-index=<file> to invoke the LTO pipeline along with function importing via clang using the supplied function summary index file. This supports invoking the parallel ThinLTO backend processes in a distributed build environment via clang. Additionally, this causes the module linker to be invoked on the bitcode file being compiled to perform any necessary promotion and renaming of locals that are exported via the function summary index file. Add a couple tests that confirm we get expected errors when we try to use the new option on a file that isn't bitcode, or specify an invalid index file. The tests also confirm that we trigger the expected function import pass.

* [PGO] Instrument only base constructors and destructors.Serge Pavlov2015-12-067-24/+18
| | | | | | | | | | | | | | | | Constructors and destructors may be represented by several functions in IR. Only base structors correspond to source code, others are small pieces of code and eventually call the base variant. In this case instrumentation of non-base structors has little sense, this fix remove it. Now profile data of a declaration corresponds to exactly one function in IR, it agrees with the current logic of the profile data loading. This change fixes PR24996.

* Fix debug info for Objective-C properties from class extensions after r251874Nico Weber2015-12-041-1/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | After r251874, properties from class extensions no longer show up in ObjCInterfaceDecl::properties(). Make debug info emission explicitly look for properties in class extensions before looking at direct properties. Also add a test that checks for this. There are three interesting cases: 1. A property is only declared in a class extension, and the @implementation is in a different file. This used to generated a DIObjcProperty before r251874 and does again with this fix. 2. A property is declared as readonly in the class itself and redeclared as readwrite in a class extension. clang before r251874 put the DIObjcProperty on the first declaration. clang after r251874 didn't emit any DIObjcProperty, and clang with this fix puts it on the readwrite redeclaration (which is what lookup finds). This seems like a progression. 3. Like 2, but with an @implementation in the same file. In this case, the property debug info gets generated a second time through the ivar from the definition. In this case, lookup and declaration code need to agree on the line number so that the DIObjcProperty isn't emitted twice. In this case, clang before r251874 emitted one DIObjcProperty on the first declaration, clang with r251874 emitted one on the second declaration, and clang with this patch still does the latter. llvm-svn: 254750
* LLDB JIT needs android vector passing rules.Stephen Hines2015-12-041-9/+26
| | | | | | | | | | | | | | | | Summary: Looking into some recent issues with LLDBs expression parser highlighted that upstream clang passes vectors types differently to Android Open Source Project's clang for Arm Android targets. This patch reflects the changes present in the AOSP and allows LLDB's JIT expression evaluation to work correctly for Arm Android targets when passing vectors. This is submitted with consent of the original author Stephen Hines.

* [OpenMP] Update target directive codegen to use 4.5 implicit data mappings.Samuel Antao2015-12-023-50/+143
| | | | | | | | | | | | | | | Summary: This patch implements the 4.5 specification for the implicit data maps. OpenMP 4.5 specification changes the default way data is captured into a target region. All the non-aggregate kinds are passed by value by default. This required activating the capturing by value during SEMA for the target region. All the non-aggregate values that can be encoded in the size of a pointer are properly casted and forwarded to the runtime library. On top of fixing the previous weird behavior for mapping pointers in nested data regions (an explicit map was always required), this also improves performance as the number of allocations/transactions to the device per non-aggregate map are reduced from two to only one - instead of passing a reference and the value, only the value passed. Explicit maps will be added later on once firstprivate, private, and map clauses' SEMA and parsing are available.
