2018-08-03[libclang 6/8] Add support for reading implicit attributesMichael Wu1-0/+22
Summary: Having access to implicit attributes is sometimes useful so users of libclang don't have to duplicate some of the logic in sema. This depends on D49081 since it also adds a CXTranslationUnit flag.

2018-08-03[libclang 1/8] Add support for ObjCObjectTypeMichael Wu1-1/+36
Summary: This patch adds support to the clang-c API for identifying ObjCObjects in CXTypes, enumerating type args and protocols on ObjCObjectTypes, and retrieving the base type of ObjCObjectTypes. Currently only ObjCInterfaceTypes are exposed, which do not have type args or protocols.

2018-05-17[libclang] Allow skipping function bodies in preamble onlyIvan Donchevskii1-0/+2
Second attempt. Fix line endings and warning. As an addition to CXTranslationUnit_SkipFunctionBodies, provide the new option CXTranslationUnit_LimitSkipFunctionBodiesToPreamble, which constraints the skipping of functions bodies to the preamble only. Function bodies in the main file are not affected if this option is set. Skipping function bodies only in the preamble is what clangd already does and the introduced flag implements it for libclang clients. Patch by Nikolai Kosjar.

2018-05-09Remove \brief commands from doxygen comments.Adrian Prantl1-2/+2
This is similar to the LLVM change https://reviews.llvm.org/D46290. We've been running doxygen with the autobrief option for a couple of years now. This makes the \brief markers into our comments redundant. Since they are a visual distraction and we don't want to encourage more \brief markers in new code either, this patch removes them all.

2018-02-21Clean up use of C allocation functionsSerge Pavlov1-0/+14
If the value returned by `malloc`, `calloc` or `realloc` is not checked for null pointer, this change replaces them for `safe_malloc`, `safe_calloc` or `safe_realloc`, which are defined in the namespace `llvm`. These function report fatal error on out of memory. In the plain C files, assertion statements are added to ensure that memory is successfully allocated. The aim of this change is to get better diagnostics of OOM on Windows. Differential Revision: https://reviews.llvm.org/D43017 llvm-svn: 325661
2018-02-12[libclang] Add `CXSymbolRole role` to CXIdxEntityRefInfoFangrui Song1-2/+25
Summary: CXIdxEntityRefInfo contains the member `CXIdxEntityRefKind kind;` to differentiate implicit and direct calls. However, there are more roles defined in SymbolRole. Among them, `Read/Write` are probably the most useful ones as they can be used to differentiate Read/Write occurrences of a symbol for document highlight in a text document.

2018-01-16[libclang] Add PrintingPolicy for pretty printing declarationsJonathan Coe1-6/+98
Summary: Introduce clang_getCursorPrettyPrinted() for pretty printing declarations. Expose also PrintingPolicy, so the user gets more fine-grained control of the entities being printed. The already existing clang_getCursorDisplayName() is pretty limited - for example, it does not handle return types, parameter names or default arguments for function declarations. Addressing these issues in clang_getCursorDisplayName() would mean to duplicate existing code (e.g. clang::DeclPrinter), so rather expose new API to access the existing functionality.

2018-01-12[CodeComplete] Add an option to omit results from the preamble.Sam McCall1-0/+2
Summary: Enumerating the contents of a namespace or global scope will omit any decls that aren't already loaded, instead of deserializing them from the PCH. This allows a fast hybrid code completion where symbols from headers are provided by an external index. (Sema already exposes the information needed to do a reasonabl job of filtering them). Clangd plans to implement this hybrid. This option is just a hint - callers still need to postfilter results if they want to *avoid* completing decls outside the main file.

by client This patch extends libclang by allowing it to record parsing operations to a temporary JSON file. The file is deleted after parsing succeeds.

2017-09-22[index] Generate class & metaclass manglings for objcDave Lee1-4/+13
Summary: ObjC classes have two associated symbols, one for the class and one for the metaclass. This change overloads `CodegenNameGenerator::getAllManglings` to produce both class and metaclass symbols. While this function is called by `clang_Cursor_getCXXManglings`, it's only called for CXXRecordDecl and CXXMethodDecl, and so libclang's behavior is unchanged.

2017-05-30[libclang] Allow to suspend a translation unit.Erik Verbruggen1-0/+2
A suspended translation unit uses significantly less memory but on the other side does not support any other calls than clang_reparseTranslationUnit to resume it or clang_disposeTranslationUnit to dispose it completely. This helps IDEs to reduce the memory footprint. The data that is freed by a call to clang_suspendTranslationUnit will be re-generated on the next (re)parse anyway. Used with a preamble, this allows pretty fast resumption of the translation unit for further use (compared to disposal of the translation unit and a parse from scratch).
