* [CodeGen] Fix assignments of inline layouts into the byref structureVedant Kumar2015-12-212-1/+5
| | | | | | | | | | | | | | When using blocks, a byref structure is created to represent the closure. The "byref.layout" field of this structure is an i8*. However, some 'inline' layouts are represented as i64's, not i8*'s. Prior to r246985 we cast the i64 'inline' layout to an i8* before assigning it into the byref structure. This patch brings the cast back and adds a regression test. rdar://23713871 llvm-svn: 256185

* [OPENMP] Remove explicit call for implicit barrierAlexey Bataev2015-12-181-20/+0
| | | | | | | #pragma omp parallel needs an implicit barrier that is currently done by an explicit call to __kmpc_barrier. However, the runtime already ensures a barrier in __kmpc_fork_call which currently leads to two barriers per region per thread. Differential Revision: http://reviews.llvm.org/D15561 llvm-svn: 255992

* [CUDA] Make vtable construction aware of host/device side of CUDA compilation.Artem Belevich2015-12-171-0/+18
| | | | | | | | | | | | | | | | | | | C++ emits vtables for classes that have key function present in the current TU. While we compile CUDA the fact that key function was found in this TU does not mean that we are going to generate code for it. E.g. vtable for a class with host-only methods should not (and can not) be generated on device side, because we'll never generate code for them during device-side compilation. This patch adds an extra CUDA-specific check during key method computation and filters out potential key methods that are not suitable for this side of CUDA compilation. When we codegen vtable, entries for unsuitable methods are set to null. Differential Revision: http://reviews.llvm.org/D15309 llvm-svn: 255911

* [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
