* [OPENMP 4.5] parsing/sema support for 'nogroup' clause.Alexey Bataev2015-12-071-0/+1
| | | | | | OpenMP 4.5 adds 'taskloop' and 'taskloop simd' directives. These directives have new 'nogroup' clause. Patch adds basic parsing/sema support for this clause. llvm-svn: 254899
* [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.

| | | | | | | | | | This reverts commit r254195. From the description, I suspect that the wrong patch was committed here, and this is causing assertion failures in EmitDeferred() when the global value ends up being a bitcast of a global. llvm-svn: 254823

* 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.

* Fix Objective-C metadata for properties from class extensions after r251874Nico Weber2015-12-031-7/+18

Make ObjCCommonMac::EmitPropertyList() explicitly look for properties in class extensions before looking at direct properties. Also add a test that passes both with clang before r251874 and after this patch (but fails with r251874 and without this patch). llvm-svn: 254622

* [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.

| | | | | | | | | | | | The pointer returned by __RTDynamicCast must be bitcasted.

* Don't actually add the __unsafe_unretained qualifier in MRC;John McCall2015-11-191-3/+9
| | | | | | | | | | | driving a canonical difference between that and an unqualified type is a really bad idea when both are valid. Instead, remember that it was there in a non-canonical way, then look for that in the one place we really care about it: block captures.

* Change memcpy/memset/memmove to have dest and source alignments.Pete Cooper2015-11-181-6/+6
| | | | | | | | | | | | | | | | | | | | | | This is a follow on from a similar LLVM commit: r253511. Note, this was reviewed (and more details are in) http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20151109/312083.html These intrinsics currently have an explicit alignment argument which is required to be a constant integer. It represents the alignment of the source and dest, and so must be the minimum of those. This change allows source and dest to each have their own alignments by using the alignment attribute on their arguments. The alignment argument itself is removed. The only code change to clang is hidden in CGBuilder.h which now passes both dest and source alignment to IRBuilder, instead of taking the minimum of dest and source alignments.

For example, int callee(int); int foo(int a) __attribute__((disable_tail_calls)) { return callee(a); // This call is not tail-call optimized. } Note that this attribute is different from 'not_tail_called', which prevents tail-call optimization to the marked function. rdar://problem/8973573 Differential Revision: http://reviews.llvm.org/D12547 llvm-svn: 252986

However, this was incorrect: while those functions are in fact supported by GCC's libatomic, they're not documented by the spec (and gcc doesn't ever call them). Instead, you're /supposed/ to call the __atomic_fetch_* builtins and then redo the operation inline to return the final value. Differential Revision: http://reviews.llvm.org/D14385 llvm-svn: 252920
