2010-08-24In code-completion contexts where both types and other values areDouglas Gregor
present, prefer values to types, since it's more common to compute with values than it is to declare new entities or perform type casts. So, tweak the ranking of types vs. other declarations and constants accordingly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111998 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-23Introduce a code-completion hook for the Objective-C collectionDouglas Gregor
argument in a for-each statement (e.g., "for (id x in <blah>)"), which restricts the expression completions provided to Objective-C types (or class types in C++). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111843 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-23Introduce a new code-completion point when we're parsing aDouglas Gregor
declarator. Here, we can only see a few things (e.g., cvr-qualifiers, nested name specifiers) and we do not want to provide other non-macro completions. Previously, we would end up in recovery mode and would provide a large number of non-relevant completions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111818 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-18Generate Attr subclasses with TableGen.Sean Hunt
Now all classes derived from Attr are generated from TableGen. Additionally, Attr* is no longer its own linked list; SmallVectors or Attr* are used. The accompanying LLVM commit contains the updates to TableGen necessary for this. Some other notes about newly-generated attribute classes: - The constructor arguments are a SourceLocation and a Context&, followed by the attributes arguments in the order that they were defined in Attr.td - Every argument in Attr.td has an appropriate accessor named getFoo, and there are sometimes a few extra ones (such as to get the length of a variadic argument). Additionally, specific_attr_iterator has been introduced, which will iterate over an AttrVec, but only over attributes of a certain type. It can be accessed through either Decl::specific_attr_begin/end or the global functions of the same name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111455 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-18Rip out the existing retroactive abstract-class usage checker,John McCall
which in a fit of zeal wanted to walk the entire translation unit, and replace it with a new checker that walks the types of declarations nested within the class. Also, look into templates when doing this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111357 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-16When caching global completion results, keep track of the simplifiedDouglas Gregor
type class, so that we can adjust priorities appropriately when the preferred type for the context and the actual type of the completion are similar. This gets us one step closer to parity of the cached completion results with the non-cached completion results. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111139 91177308-0d34-0410-b5e6-96231b3b80d8
2010-08-15Extend the code-completion caching infrastructure to include globalDouglas Gregor
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111093 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
