2012-03-13[libclang] When there's a file error when saving the PCH, make sure toArgyrios Kyrtzidis
clear the error from raw_fd_ostream, otherwise we will crash. rdar://10976410 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152605 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-11Unify naming of LangOptions variable/get function across the Clang stack ↵David Blaikie
(Lex to AST). The member variable is always "LangOpts" and the member function is always "getLangOpts". Reviewed by Chris Lattner git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152536 91177308-0d34-0410-b5e6-96231b3b80d8
2012-03-07[PCH] Mark a PCH file with a flag to indicate if the serialized AST hadArgyrios Kyrtzidis
compiler errors or not. -Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time. 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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152192 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-23[libclang] Fix operations (token annotation, getting cursor, etc.) with a ↵Argyrios Kyrtzidis
file region inside an objc container that "contains" other file-level declarations. When getting the array of file-level declarations that overlap with a file region, we failed to report that the region overlaps with an objc container, if the container had other file-level declarations declared lexically inside it. Fix this by marking such declarations as "isTopLevelDeclInObjCContainer" in the AST and handling them appropriately. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@145109 91177308-0d34-0410-b5e6-96231b3b80d8

2011-11-17Make 'LangOptions' in CompilerInvocation a heap-allocated, reference counted ↵Ted Kremenek
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@144930 91177308-0d34-0410-b5e6-96231b3b80d8
