2011-07-30When performing code completion after at @interface, allow bothDouglas Gregor
already-defined and forward-declared results. Already-defined results are fine because they could be the start of a category. Fixes <rdar://problem/9811691>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@136559 91177308-0d34-0410-b5e6-96231b3b80d8

2011-07-07Introduce a new libclang aPI function,Douglas Gregor
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! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@134615 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-23Implement a new 'availability' attribute, that allows one to specifyDouglas Gregor
which versions of an OS provide a certain facility. For example, void foo() __attribute__((availability(macosx,introduced=10.2,deprecated=10.4,obsoleted=10.6))); says that the function "foo" was introduced in 10.2, deprecated in 10.4, and completely obsoleted in 10.6. This attribute ties in with the deployment targets (e.g., -mmacosx-version-min=10.1 specifies that we want to deploy back to Mac OS X 10.1). There are several concrete behaviors that this attribute enables, as illustrated with the function foo() above: - If we choose a deployment target >= Mac OS X 10.4, uses of "foo" will result in a deprecation warning, as if we had placed attribute((deprecated)) on it (but with a better diagnostic) - If we choose a deployment target >= Mac OS X 10.6, uses of "foo" will result in an "unavailable" warning (in C)/error (in C++), as if we had placed attribute((unavailable)) on it - If we choose a deployment target prior to 10.2, foo() is weak-imported (if it is a kind of entity that can be weak imported), as if we had placed the weak_import attribute on it. Naturally, there can be multiple availability attributes on a declaration, for different platforms; only the current platform matters when checking availability attributes. The only platforms this attribute currently works for are "ios" and "macosx", since we already have -mxxxx-version-min flags for them and we have experience there with macro tricks translating down to the deprecated/unavailable/weak_import attributes. The end goal is to open this up to other platforms, and even extension to other "platforms" that are really libraries (say, through a #pragma clang define_system), but that hasn't yet been designed and we may want to shake out more issues with this narrower problem first. Addresses <rdar://problem/6690412>. As a drive-by bug-fix, if an entity is both deprecated and unavailable, we only emit the "unavailable" diagnostic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128127 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-18When code-completing a case statement for a switch on a value ofDouglas Gregor

2011-02-17Implement code completion results for the Objective-C Key-Value CodingDouglas Gregor
(KVC) and Key-Value Observing (KVO) protocols. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@125696 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-02Revert r124704, which uniqued code-completion strings. The spaceDouglas Gregor
savings of 25% sounds impressive, except that this amounted to only about 360k in our standard "large" completion result set (40,000 results). Since code completion is performance-sensitive, the 4% slowdown due to uniquing outweighs the 360k benefit. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124737 91177308-0d34-0410-b5e6-96231b3b80d8
2011-02-01Unique code-completion strings. On Cocoa.h, this costs us about 4% inDouglas Gregor

2011-02-01Create a special allocator class for code completion, so that all ofDouglas Gregor

2011-02-01Allocate CodeCompletionString and all of its components in aDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@124673 91177308-0d34-0410-b5e6-96231b3b80d8
2010-10-11Eliminate the (de-)serialization of code completion results, now thatDouglas Gregor
libclang does not support out-of-process code completion. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@116253 91177308-0d34-0410-b5e6-96231b3b80d8
2010-09-23Synchronize globally-cached code completion results with the resultsDouglas Gregor
provided when the optimization is disabled. In particular, split the completion context CCC_Other into two contexts: CCC_Other, which means that it's an undisclosed context for which any other results are unwelcome, and CCC_Recovery, which is used in recovery cases. Since we're now using the completion context within the completion results builder, make sure that it's always set to something. Fixes <rdar://problem/8470644>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@114704 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-13Implement caching of code-completion results for macro definitionsDouglas Gregor
when the CXTranslationUnit_CacheCompletionResults option is given to clang_parseTranslationUnit(). Essentially, we compute code-completion results for macro definitions after we have parsed the file, then store an ASTContext-agnostic version of those results (completion string, cursor kind, priority, and active contexts) in the ASTUnit. When performing code completion in that ASTUnit, we splice the macro definition results into the results provided by the actual code-completion (which has had macros turned off) before libclang gets those results. We use completion context information to only splice in those results that make sense for that context. With a completion involving all of the macros from Cocoa.h and a few other system libraries (totally ~8500 macro definitions) living in a precompiled header, we get about a 9% performance improvement from code completion, since we no longer have to deserialize all of the macro definitions from the precompiled header. Note that macro definitions are merely the canary; the cache is designed to also support other top-level declarations, which should be a bigger performance win. That optimization will be next. Note also that there is no mechanism for determining when to throw away the cache and recompute its contents. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111051 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-11Once code completion has completed, pass a "completion context" on toDouglas Gregor
the code-completion consumer. The consumer can use this information to augument, filter, or display the code-completion results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110858 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-04Add code-completion support directly to ASTUnit, which performs codeDouglas Gregor
completion within the translation unit using the same command-line arguments for parsing the translation unit. Eventually, we'll reuse the precompiled preamble to improve code-completion performance, and this also gives us a place to cache results. Expose this function via the new libclang function clang_codeCompleteAt(), which performs the code completion within a CXTranslationUnit. The completion occurs in-process (clang_codeCompletion() runs code completion out-of-process). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@110210 91177308-0d34-0410-b5e6-96231b3b80d8

2010-05-25Improve code completion in failure cases in two ways:Douglas Gregor
1) Suppress diagnostics as soon as we form the code-completion token, so we don't get any error/warning spew from the early end-of-file. 2) If we consume a code-completion token when we weren't expecting one, go into a code-completion recovery path that produces the best results it can based on the context that the parser is in. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@104585 91177308-0d34-0410-b5e6-96231b3b80d8
2010-04-17Add raw_ostream operators to NamedDecl for convenience. Switch over all ↵Benjamin Kramer

2010-04-07Implement code completion for Objective-C method declarations andDouglas Gregor
definitions, e.g., after - or - (id) we'll find all of the "likely" instance methods that one would want to declare or define at this point. In the latter case, we only produce results whose return types match "id". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@100587 91177308-0d34-0410-b5e6-96231b3b80d8

2010-01-19Eliminate cursor kinds used to express definitions. Instead, provideDouglas Gregor
CIndex functions that (1) map from a reference or declaration to the corresponding definition, if available, and (2) determine whether a given declaration cursor is also a definition. This eliminates a lot of duplication in the cursor kinds, and maps more closely to the Clang ASTs. This is another API + ABI breaker with no deprecation. Yay, progress. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93893 91177308-0d34-0410-b5e6-96231b3b80d8
2010-01-13Improve the sorting of code-completion results. We now always sort byDouglas Gregor

2010-01-10Improve code completion by introducing patterns for the various C andDouglas Gregor
C++ grammatical constructs that show up in top-level (namespace-level) declarations, member declarations, template declarations, statements, expressions, conditions, etc. For example, we now provide a pattern for static_cast<type>(expr) when we can have an expression, or using namespace identifier; when we can have a using directive. Also, improves the results of code completion at the beginning of a top-level declaration. Previously, we would see value names (function names, global variables, etc.); now we see types, namespace names, etc., but no values. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@93134 91177308-0d34-0410-b5e6-96231b3b80d8

- Provide Sema in callbacks, instead of requiring it in constructor. This eliminates the need for a factory function.
