| | | | | | | | | AllocatedResults being freed after a CXTranslationUnit. The Container USR's CXString had its underlying data owned by the CXTranslationUnit's string pool. This would result in trying to access freed memory. llvm-svn: 137887

| | | | | | | | | clang_codeCompleteGetContexts(), that provides the client with information about the context in which code completion has occurred and what kinds of entities make sense as completions at that point. Patch by Connor Wakamo! llvm-svn: 134615

* Improve crash recovery cleanup to recovery CompilerInstances during crash ↵Ted Kremenek2011-03-211-6/+6
| | | | | | | | | | recovery. This was a huge resource "root" during crashes. This change requires making a bunch of fundamental Clang structures (optionally) reference counted to allow correct ownership semantics of these objects (e.g., ASTContext) to play out between an active ASTUnit and CompilerInstance object. llvm-svn: 128011

* Allocate CodeCompletionString and all of its components in aDouglas Gregor2011-02-011-48/+26
| | | | | | | | | | | | BumpPtrAllocator, rather than manually new/delete'ing them. This optimization also allows us to avoid allocating memory for and copying constant strings (e.g., "return", "class"). This also required embedding the priority and availability of results within the code completion string, to avoid extra memory allocation within libclang. llvm-svn: 124673

* now the FileManager has a FileSystemOpts ivar, stop threadingChris Lattner2010-11-231-4/+4
| | | | | | | | | FileSystemOpts through a ton of apis, simplifying a lot of code. This also fixes a latent bug in ASTUnit where it would invoke methods on FileManager without creating one in some code paths in cindextext. llvm-svn: 120010
* give FileManager a 'FileSystemOptions' ivar, which will be usedChris Lattner2010-11-231-1/+3
| | | | | | | to simplify a bunch of code in it. It should ultimately get inlined into FileManager. llvm-svn: 120007
* Refactoring of Diagnostic class.Argyrios Kyrtzidis2010-11-181-1/+3
| | | | | | | | | | | -Move the stuff of Diagnostic related to creating/querying diagnostic IDs into a new DiagnosticIDs class. -DiagnosticIDs can be shared among multiple Diagnostics for multiple translation units. -The rest of the state in Diagnostic object is considered related and tied to one translation unit. -Have Diagnostic point to the SourceManager that is related with. Diagnostic can now accept just a SourceLocation instead of a FullSourceLoc. -Reflect the changes to various interfaces. llvm-svn: 119730
* Make definition of CXTranslationUnitImpl privateTed Kremenek2010-11-171-0/+1

* Fix source-range information for Objective-C properties. Previously,Douglas Gregor2010-11-171-1/+17
| | | | | | | | | | | | we were just getting a range covering only the property name, which is certainly not correct (and broke token annotation, among other things). Also, teach libclang about the relationship between @synthesize/@dynamic and @property, so we get property name and cursor-reference information for @synthesize and @dynamic. llvm-svn: 119409
* Change CXTranslationUnit to not directly cast to an ASTUnit*,Ted Kremenek2010-11-161-4/+4
| | | | | | | | | | | | | | | | | | | but to wrap both an ASTUnit and a "string pool" that will be used for fast USR generation. This requires a bunch of mechanical changes, as there was a ton of code that assumed that CXTranslationUnit and ASTUnit* were the same. Along with this change, introduce CXStringBuf, which provides an llvm::SmallVector<char> backing for repeatedly generating CXStrings without a huge amount of malloc() traffic. This requires making some changes to the representation of CXString by renaming a few fields (but keeping the size of the object the same). llvm-svn: 119337
* Move CXString creation/management routines intoTed Kremenek2010-11-161-0/+1

* libclang: Add some support for running certain entry points in a "safety"Daniel Dunbar2010-11-051-1/+1

* Implement -working-directory.Argyrios Kyrtzidis2010-11-031-4/+7
| | | | | | | | | | | | | | | | | | | When -working-directory is passed in command line, file paths are resolved relative to the specified directory. This helps both when using libclang (where we can't require the user to actually change the working directory) and to help reproduce test cases when the reproduction work comes along. --FileSystemOptions is introduced which controls how file system operations are performed (currently it just contains the working directory value if set). --FileSystemOptions are passed around to various interfaces that perform file operations. --Opening & reading the content of files should be done only through FileManager. This is useful in general since file operations will be abstracted in the future for the reproduction mechanism. FileSystemOptions is independent of FileManager so that we can have multiple translation units sharing the same FileManager but with different FileSystemOptions. Addresses rdar://8583824. llvm-svn: 118203
* Introduce code completion results for Objective-C methods, both whenDouglas Gregor2010-10-181-6/+52
| | | | | | | | | declaring methods and when sending messages to them, by bringing all of the selector into TypedCheck chunks in the completion result. This way, we can improve the sorting of these results to account for the full selector name rather than just the first chunk. llvm-svn: 116746

| | | | | | | | | | clang_codeCompleteAt(). This uncovered a few issues with the latter: - ASTUnit wasn't saving/restoring diagnostic state appropriately between reparses and code completions. - "Overload" completions weren't being passed through to the client llvm-svn: 116241

* When performing code-completion in the presence of a preamble, makeDouglas Gregor2010-08-201-6/+2
| | | | | | | | | sure to (1) actually use the remapped files we were given rather than old data, and (2) keep the remapped files alive until the code-completion results are destroyed. Big thanks to Daniel for the test case. llvm-svn: 111597
* libclang: Execute clang_codeCompleteAt() inside a crash recovery context.Daniel Dunbar2010-08-191-9/+44

* Extend the code-completion caching infrastructure to include globalDouglas Gregor2010-08-151-1/+2
| | | | | | | | | | | | | | | | | | declarations (in addition to macros). Each kind of declaration maps to a certain set of completion contexts, and the ASTUnit completion logic introduces the completion strings for those declarations if the actual code-completion occurs in one of the contexts where it matters. There are a few new code-completion-context kinds. Without these, certain completions (e.g., after "using namespace") would need to suppress all global completions, which would be unfortunate. Note that we don't get the priorities right for global completions, because we don't have enough type information. We'll need a way to compare types in an ASTContext-agnostic way before this can be implemented. llvm-svn: 111093
