For example, if we have something like: template< typename Iter, typename = std::enable_if_t<Random_access_iterator<Iter> && Comparable<Iterator_value_type<Iter>>>> void mysort(Iter first, Iter last) {} and we call "mysort" with "std::list<int>" iterators, we'll get a diagnostic saying that the "Random_access_iterator<Iter>" requirement failed. If we call "mysort" with "std::vector<something_not_comparable>", we'll get a diagnostic saying that the "Comparable<...>" requirement failed. llvm-svn: 307196

2017-07-01[modules] Teach clang how to merge typedef over anonymous structs in C mode.Vassil Vassilev1-1/+1
In C mode clang fails to merge the textually included definition with the one imported from a module. The C lookup rules fail to find the imported definition because its linkage is internal in non C++ mode. This patch reinstates some of the ODR merging rules for typedefs of anonymous tags for languages other than C++. Patch by Raphael Isemann and me (D34510). llvm-svn: 306964
2017-07-01[OpenMP] Fix mapping of scalars for combined directivesJonas Hahnfeld1-0/+26
Combined directives like 'target parallel' have two captured statements. Sema has to check the right one from the right direction. Previously, Sema::IsOpenMPCapturedByRef would return false for mapped scalars on combined directives. This results in a wrong signature of the outlined function which triggers an assertion: void llvm::CallInst::init(llvm::FunctionType *, llvm::Value *, ArrayRef<llvm::Value *>, ArrayRef<OperandBundleDef>, const llvm::Twine &): Assertion `(i >= FTy->getNumParams() || FTy->getParamType(i) == Args[i]->getType()) && "Calling a function with a bad signature!"' failed.

2017-07-01[Driver] Add -fdiagnostics-hotness-thresholdBrian Gesiak2-5/+17
Summary: Depends on https://reviews.llvm.org/D34867. Add a Clang frontend option to enable optimization remark hotness thresholds, which were added to LLVM in https://reviews.llvm.org/D34867. This prevents diagnostics that do not meet a minimum hotness threshold from being output. When generating optimization remarks for large codebases with a ton of cold code paths, this option can be used to limit the optimization remark output at a reasonable size.

The following changes are made to the driver since 32-bit apps do not run on iOS 11 or later: - If the deployment target is set explicitly, either with a command-line option or an environment variable, the driver should report an error if the version is greater than iOS 10. - In the case where the deployment target is not set explicitly and the default is inferred from the target triple or SDK version, it should use a maximum default of iOS 10.99.99. rdar://problem/32230613 Differential Revision: https://reviews.llvm.org/D34529 llvm-svn: 306922
2017-07-01[Modules] Implement ODR-like semantics for tag types in C/ObjCBruno Cardoso Lopes7-13/+86
Allow ODR for ObjC/C in the sense that we won't keep more that one definition around (merge them). However, ensure the decl pass the structural compatibility check in C11 6.2.7/1, for that, reuse the structural equivalence checks used by the ASTImporter. Few other considerations: - Create error diagnostics for tag types mismatches and thread them into the structural equivalence checks. - Note that by doing this we only support redefinition between types that are considered "compatible types" by C. This is mixed approach of the suggestions discussed in http://lists.llvm.org/pipermail/cfe-dev/2017-March/053257.html Differential Revision: https://reviews.llvm.org/D31778 rdar://problem/31909368 llvm-svn: 306918

Summary: This patch aims to fix the bug reported at https://bugs.llvm.org/show_bug.cgi?id=33189. Clang hits an assertion when a template destructor declaration is present. This is caused by later processing that does not expect to encounter a template when looking at a destructor. The resolution is to treat the destructor as being not declared when later processing is interested in the properties of the destructor of a class.

2017-06-30[objc] Don't require null-check and don't emit memset when result is ignored ↵Kuba Mracek2-1/+44
for struct-returning method calls [clang part] This fixes an issue with the emission of lifetime markers for struct-returning Obj-C msgSend calls. When the result of a struct-returning call is ignored, the temporary storage is only marked with lifetime markers in one of the two branches of the nil-receiver-check. The check is, however, not required when the result is unused. If we still need to emit the check (due to consumer arguments), let's not emit the memset to zero out the result if it's unused. This fixes a use-after-scope false positive with AddressSanitizer. Differential Revision: https://reviews.llvm.org/D34834 llvm-svn: 306837
