* Model type attributes as regular Attrs.Richard Smith2018-08-1316-562/+498
| | | | | | | | | | Specifically, AttributedType now tracks a regular attr::Kind rather than having its own parallel Kind enumeration, and AttributedTypeLoc now holds an Attr* instead of holding an ad-hoc collection of Attr fields.

* [analyzer][UninitializedObjectChecker] Refactoring p4.: Wrap FieldRegions ↵Kristof Umann2018-08-133-113/+201
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and reduce weight on FieldChainInfo Before this patch, FieldChainInfo used a spaghetti: it took care of way too many cases, even though it was always meant as a lightweight wrapper around ImmutableList<const FieldRegion *>. This problem is solved by introducing a lightweight polymorphic wrapper around const FieldRegion *, FieldNode. It is an interface that abstracts away special cases like pointers/references, objects that need to be casted to another type for a proper note messages. Changes to FieldChainInfo: * Now wraps ImmutableList<const FieldNode &>. * Any pointer/reference related fields and methods were removed * Got a new add method. This replaces it's former constructors as a way to create a new FieldChainInfo objects with a new element. Changes to FindUninitializedField: * In order not to deal with dynamic memory management, when an uninitialized field is found, the note message for it is constructed and is stored instead of a FieldChainInfo object. (see doc around addFieldToUninits). Some of the test files are changed too, from now on uninitialized pointees of references always print "uninitialized pointee" instead of "uninitialized field" (which should've really been like this from the beginning). I also updated every comment according to these changes. Differential Revision: https://reviews.llvm.org/D50506 llvm-svn: 339599

Otherwise the getFriendDecl of the FriendDecl can point to an other already referenced declaration, this case causes problems. Additionally the previous decl of class templates is set at import.

* [analyzer] Record nullability implications on getting items from NSDictionaryGeorge Karpenkov2018-08-101-14/+173
| | | | | | | | | | | | | | | | | | | | If we get an item from a dictionary, we know that the item is non-null if and only if the key is non-null. This patch is a rather hacky way to record this implication, because some logic needs to be duplicated from the solver. And yet, it's pretty simple, performant, and works. Other possible approaches: - Record the implication, in future rely on Z3 to pick it up. - Generalize the current code and move it to the constraint manager. rdar://34990742 Differential Revision: https://reviews.llvm.org/D50124 llvm-svn: 339482

* [CodeGen] Merge equivalent block copy/helper functions.Akira Hatanaka2018-08-1010-78/+289
| | | | | | | | | | | | | | | | | | | | | | | Clang generates copy and dispose helper functions for each block literal on the stack. Often these functions are equivalent for different blocks. This commit makes changes to merge equivalent copy and dispose helper functions and reduce code size. To enable merging equivalent copy/dispose functions, the captured object infomation is encoded into the helper function name. This allows IRGen to check whether an equivalent helper function has already been emitted and reuse the function instead of generating a new helper function whenever a block is defined. In addition, the helper functions are marked as linkonce_odr to enable merging helper functions that have the same name across translation units and marked as unnamed_addr to enable the linker's deduplication pass to merge functions that have different names but the same content. rdar://problem/42640608 Differential Revision: https://reviews.llvm.org/D50152 llvm-svn: 339438

* [ADT] Normalize empty triple componentsPetr Hosek2018-08-082-3/+2
| | | | | | | | | | | | | | | | | LLVM triple normalization is handling "unknown" and empty components differently; for example given "x86_64-unknown-linux-gnu" and "x86_64-linux-gnu" which should be equivalent, triple normalization returns "x86_64-unknown-linux-gnu" and "x86_64--linux-gnu". autoconf's config.sub returns "x86_64-unknown-linux-gnu" for both "x86_64-linux-gnu" and "x86_64-unknown-linux-gnu".
