* [SE] Platforms return Device valuesJason Henline2016-09-134-24/+19
| | | | | | | | | | | | | | | Summary: Platforms were returning Device pointers, but a Device is now basically just a pointer to an underlying PlatformDevice, so we will now just pass it around as a value.

* Force c++14 when running tests on Windows.Zachary Turner2016-09-131-0/+1
| | | | | | | | | VS 2015 and higher begin making use of c++14 in their standard library headers. As such, -std=c++11 makes it so you can't compile trivial programs. Bump this to -std=c++14 when this situation is detected. llvm-svn: 281420
* [ObjCARC] Traverse chain downwards to replace uses of argument passed toAkira Hatanaka2016-09-132-4/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ObjC library call with call return. ARC contraction tries to replace uses of an argument passed to an objective-c library call with the call return value. For example, in the following IR, it replaces uses of argument %9 and uses of the values discovered traversing the chain upwards (%7 and %8) with the call return %10, if they are dominated by the call to @objc_autoreleaseReturnValue. This transformation enables code-gen to tail-call the call to @objc_autoreleaseReturnValue, which is necessary to enable auto release return value optimization. %7 = tail call i8* @objc_loadWeakRetained(i8** %6) %8 = bitcast i8* %7 to %0* %9 = bitcast %0* %8 to i8* %10 = tail call i8* @objc_autoreleaseReturnValue(i8* %9) ret %0* %8 Since r276727, llvm started removing redundant bitcasts and as a result started feeding the following IR to ARC contraction: %7 = tail call i8* @objc_loadWeakRetained(i8** %6) %8 = bitcast i8* %7 to %0* %9 = tail call i8* @objc_autoreleaseReturnValue(i8* %7) ret %0* %8 ARC contraction no longer does the optimization described above since it only traverses the chain upwards and fails to recognize that the function return can be replaced by the call return. This commit changes ARC contraction to traverse the chain downwards too and replace uses of bitcasts with the call return. rdar://problem/28011339 Differential Revision: https://reviews.llvm.org/D24523 llvm-svn: 281419
* TestQueues could error out because the one second sleep main.c wasJason Molenda2016-09-132-3/+6
| | | | | | | | using to enqueue all the jobs wasn't enough time on a slow/overloaded system. Instead use a global to indicate when all the work has been enqueued, let's see if this makes the CIs work more reliably. llvm-svn: 281418
* [SE] KernelSpec return best PTXJason Henline2016-09-133-12/+15
| | | | | | | | | | | | | | | | Summary: Before, the kernel spec would only return PTX for exactly the requested compute capability. With this patch it will now return the PTX with the largest compute capability that does not exceed that requested compute capability.

* revert: [ELF] - Versionscript: support mangled symbols with the same name.George Rimar2016-09-133-41/+16
| | | | | | | | | | | | | | | | | | | | | | | | | Something broked BBots: 281318 failed on step 9: http://lab.llvm.org:8011/builders/clang-with-lto-ubuntu/builds/413 r281317 built step 9 green: http://lab.llvm.org:8011/builders/clang-with-lto-ubuntu/builds/415 Initial revision commits were: This is PR30312. Info from bug page: Both of these symbols demangle to abc::abc(): _ZN3abcC1Ev _ZN3abcC2Ev (These would be abc's complete object constructor and base object constructor, respectively.) however with "abc::abc()" in the version script only one of the two receives the symbol version.

* [asan] alloc_dealloc_mismatch=0 by default on Android.Evgeniy Stepanov2016-09-133-6/+4

* [CUDA] Do not merge CUDA target attributes.Artem Belevich2016-09-133-1/+47
| | | | | | | | | | | | CUDA target attributes are used for function overloading and must not be merged.

* [CodeGen] Fix an assert in EmitNullConstant.Akira Hatanaka2016-09-132-1/+23
| | | | | | | | | | | | | | | r235815 changed CGRecordLowering::accumulateBases to ignore non-virtual bases of size 0, which prevented adding those non-virtual bases to CGRecordLayout's NonVirtualBases. This caused clang to assert when CGRecordLayout::getNonVirtualBaseLLVMFieldNo was called in EmitNullConstant. This commit fixes the bug by ignoring zero-sized non-virtual bases in EmitNullConstant. rdar://problem/28100139 Differential Revision: https://reviews.llvm.org/D24312 llvm-svn: 281405

* [DAG] Allow build-to-shuffle combine to combine builds from two wide vectors.Michael Kuperstein2016-09-132-126/+84
| | | | | | | | | | | This allows us to, in some cases, create a vector_shuffle out of a build_vector, when the inputs to the build are extract_elements from two different vectors, at least one of which is wider than the output. (E.g. a <8 x i16> being constructed out of elements from a <16 x i16> and a <8 x i16>). Differential Revision: https://reviews.llvm.org/D24491 llvm-svn: 281402

To ensure I don't break anything, I'm adding some unit tests for this function. As a side benefit, this also expands test coverage of this function to all platforms, since in general this code would rarely be exercised on non Mac platforms, and never in the test suite. llvm-svn: 281387

* [SemaObjC] Be more strict while parsing type arguments and protocolsBruno Cardoso Lopes2016-09-134-2/+54
| | | | | | | | | | | | | | | | | | | | Fix a crash-on-invalid. When parsing type arguments and protocols, parseObjCTypeArgsOrProtocolQualifiers() calls ParseTypeName(), which tries to find matching tokens for '[', '(', etc whenever they appear among potential type names. If unmatched, ParseTypeName() yields a tok::eof token stream. This leads to crashes since the parsing at this point is not expected to go beyond the param list closing '>'. Fix that by properly handling tok::eof in parseObjCTypeArgsOrProtocolQualifiers() callers. Differential Revision: https://reviews.llvm.org/D23852 rdar://problem/25063557 llvm-svn: 281383
