* If the precompiled header named by "-include" is actually a directory,Douglas Gregor2012-10-231-9/+2
| | | | | | | | | check each of the files within that directory to determine if any of them is an AST file that matches the language and target options. If so, the first matching AST file is loaded. This fixes a longstanding discrepency with GCC's precompiled header implementation. llvm-svn: 166469

* [libclang] Improve AST serialization done by ASTUnit::Save().Argyrios Kyrtzidis2012-10-111-28/+64
| | | | | | | | | The ASTUnit needs to initialize an ASTWriter at the beginning of parsing to fully handle serialization of a translation unit that imports modules. Do this by introducing an option to enable it, which corresponds to CXTranslationUnit_ForSerialization on the C API side. llvm-svn: 165717

* Introduce a flag in SourceManager to treat non-system source filesArgyrios Kyrtzidis2012-07-111-8/+20
| | | | | | | | | | | | | | | | | | | | as "volatile", meaning there's a high enough chance that they may change while we are trying to use them. This flag is only enabled by libclang. Currently "volatile" source files will be stat'ed immediately before opening them, because the file size stat info may not be accurate since when we got it (e.g. from the PCH). This avoids crashes when trying to reference mmap'ed memory from a file whose size is not what we expect. Note that there's still a window for a racing issue to occur but the window for it should be way smaller than before. We can consider later on to avoid mmap completely on such files. rdar://11612916 llvm-svn: 160074

* Add a new libclang completion API to get brief documentation comment that isDmitri Gribenko2012-07-021-17/+31
| | | | | | | | | | | | | | | | attached to a declaration in the completion string. Since extracting comments isn't free, a new code completion option is introduced. A new code completion option that enables including brief comments into CodeCompletionString should be a, err, code completion option. But because ASTUnit caches global declarations during parsing before even completion consumer is created, the option is duplicated as a translation unit option (in both libclang and ASTUnit, like the option to cache code completion results). llvm-svn: 159539

* [code-complete] Introduce CodeCompletionTUInfo which will be used for cachingArgyrios Kyrtzidis2012-04-101-9/+17
| | | | | | | | | | | | | | | | | | | code-completion related strings specific to a translation unit (ASTContext and related data) CodeCompletionAllocator does such limited caching, by caching the name assigned to a DeclContext*, but that is not the appropriate place since that object has a lifetime that can extend beyond that of an ASTContext. Introduce CodeCompletionTUInfo which will be always tied to a translation unit to do this kind of caching and move the caching of CodeCompletionAllocator into this object, and propagate it to all the places where it will be needed. The plan is to extend the caching where appropriate, using CodeCompletionTUInfo, to avoid re-calculating code-completion strings. Part of rdar://10796159. llvm-svn: 154408

* Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie2012-03-111-5/+5

By default, such a PCH file will be rejected with an error when trying to load it. [libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors occurred. -Have libclang API calls accept a PCH that had compiler errors. The general idea is that we want libclang to stay functional even if a PCH had a compiler error. rdar://10976363. llvm-svn: 152192

* Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted ↵Ted Kremenek2011-11-171-2/+3
| | | | | | | | | | | | | | | | | object. I discovered that llvm::RefCountedBase<T> has a bug where the reference count is copied in the copy constructor, which means that there were cases when the CompilerInvocation objects created by ASTUnit were actually leaked. When I fixed that bug locally, it showed that a whole bunch of code assumed that the LangOptions object that was part of CompilerInvocation was still alive. By making it heap-allocated and reference counted, we can keep it around after the CompilerInvocation object goes away. As part of this change, change CompilerInvocation:getLangOptions() to return a pointer, acting as another clue that this object may outlive the CompilerInvocation object. This commit doesn't fix the CompilerInvocation leak itself. That will come when I commit the fix to llvm::RefCountedBase<T> to mainline LLVM. llvm-svn: 144930
