* [ObjC] Fix type checking for qualified id block parameters.Volodymyr Sapsai2019-08-282-3/+14
| | | | | | | | | | | | | | | | | | When checking if block types are compatible, we are checking for compatibility their return types and parameters' types. As these types have different variance, we need to check them in different order. rdar://problem/52788423 Reviewers: erik.pilkington, arphaman Reviewed By: arphaman Subscribers: jkorous, dexonsmith, ributzka, cfe-commits Differential Revision: https://reviews.llvm.org/D66831 llvm-svn: 370130

* Move EH spec mismatches under -fms-compatibilityReid Kleckner2019-08-275-51/+52
| | | | | | | | | | | | | | | | | | | | | -fms-extensions is intended to enable conforming language extensions and -fms-compatibility is intended to language rule relaxations, so a user could plausibly compile with -fno-ms-compatibility on Windows while still using dllexport, for example. This exception specification validation behavior has been handled as a warning since before -fms-compatibility was added in 2011. I think it's just an oversight that it hasn't been moved yet. This will help users find conformance issues in their code such as those found in _com_ptr_t as described in https://llvm.org/PR42842.

* [RISCV] Set MaxAtomicInlineWidth and MaxAtomicPromoteWidth for RV32/RV64 ↵Sam Elliott2019-08-274-0/+260
| | | | | | | | | | | | | | | | | | targets with atomics Summary: This ensures that libcalls aren't generated when the target supports atomics. Atomics aren't in the base RV32I/RV64I instruction sets, so MaxAtomicInlineWidth and MaxAtomicPromoteWidth are set only when the atomics extension is being targeted. This must be done in setMaxAtomicWidth, as this should be done after handleTargetFeatures has been called.

* [ASTImporter] Fix name conflict handling with different strategiesGabor Marton2019-08-276-113/+447
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are numorous flaws about the name conflict handling, this patch attempts fixes them. Changes in details: * HandleNameConflict return with a false DeclarationName Hitherto we effectively never returned with a NameConflict error, even if the preceding StructuralMatch indicated a conflict. Because we just simply returned with the parameter `Name` in HandleNameConflict and that name is almost always `true` when converted to `bool`. * Add tests which indicate wrong NameConflict handling * Add to ConflictingDecls only if decl kind is different Note, we might not indicate an ODR error when there is an existing record decl and a enum is imported with same name. But there are other cases. E.g. think about the case when we import a FunctionTemplateDecl with name f and we found a simple FunctionDecl with name f. They overload. Or in case of a ClassTemplateDecl and CXXRecordDecl, the CXXRecordDecl could be the 'templated' class, so it would be false to report error. So I think we should report a name conflict error only when we are 100% sure of that. That is why I think it should be a general pattern to report the error only if the kind is the same. * Fix failing ctu test with EnumConstandDecl In ctu-main.c we have the enum class 'A' which brings in the enum constant 'x' with value 0 into the global namespace. In ctu-other.c we had the enum class 'B' which brought in the same name ('x') as an enum constant but with a different enum value (42). This is clearly an ODR violation in the global namespace. The solution was to rename the second enum constant. * Introduce ODR handling strategies Reviewers: a_sidorin, shafik Differential Revision: https://reviews.llvm.org/D59692 llvm-svn: 370045

| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Previously, it would always return nullptr on any error. This change adds a parameter, controlling whether the function should attempt to return a non-null result even if unknown arguments (or other errors were encountered). The new behavior is only used in clangd. Considered an alternative of changing the return value instead of adding a new parameter, but that would require updating all callsites. Settled with the parameter to minimize the code changes.

Instead of trying to reconstruct whether a parameter pack was declared inside a lambda (which we can't do correctly in general because we might not have attached parameters to their declaration contexts yet), track the set of parameter packs introduced in each live lambda scope, and require only those parameters to be immediately expanded when they appear inside that lambda. In passing, fix incorrect disambiguation of a lambda-expression starting with an init-capture pack in a braced-init-list.
