2009-09-21Change all the Type::getAsFoo() methods to specializations of Type::getAs().John McCall
Several of the existing methods were identical to their respective specializations, and so have been removed entirely. Several more 'leaf' optimizations were introduced. The getAsFoo() methods which imposed extra conditions, like getAsObjCInterfacePointerType(), have been left in place. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82501 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-21Enhance "case" code completion in C++ to suggest qualified names forDouglas Gregor

2009-09-18Introduce four new code-completion hooks for C++:Douglas Gregor
- after "using", show anything that can be a nested-name-specifier. - after "using namespace", show any visible namespaces or namespace aliases - after "namespace", show any namespace definitions in the current scope - after "namespace identifier = ", show any visible namespaces or namespace aliases git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82251 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-18For code completion in C++ member access expressions and tag names,Douglas Gregor
look into the current scope for anything that could start a nested-names-specifier. These results are ranked worse than any of the results actually found in the lexical scope. Perform a little more pruning of the result set, eliminating constructors, __va_list_tag, and any duplication of declarations in the result set. For the latter, implemented NamespaceDecl::getCanonicalDecl. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82231 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18When gathering results for code completion, only include hiddenDouglas Gregor
results when there is some way to refer to them in the language, such as with a qualified name in C++. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82223 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Implement code completion for tags, e.g., code completion after "enum"Douglas Gregor
will provide the names of various enumerations currently visible. Introduced filtering of code-completion results when we build the result set, so that we can identify just the kinds of declarations we want. This implementation is incomplete for C++, since we don't consider that the token after the tag keyword could start a nested-name-specifier. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82222 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Revert most of r82198, which was causing a large number of crashesTed Kremenek
when running the analyzer on real projects. We'll keep the change to AnalysisManager.cpp in r82198 so that -fobjc-gc analyzes code correctly in both GC and non-GC modes, although this may emit two diagnostics for each bug in some cases (a better solution will come later). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82201 91177308-0d34-0410-b5e6-96231b3b80d8
2009-09-18Introduce caching of diagnostics in BugReporter. This provides extraTed Kremenek
pruning of diagnostics that may be emitted multiple times. This is accomplished by adding FoldingSet profiling support to PathDiagnostic, and then having BugReporter record what diagnostics have been issued. This was motived to a serious bug introduced by moving the 'divide-by-zero' checking outside of GRExprEngine into a separate 'Checker' class. When analyzing code using the '-fobjc-gc' option, a given function would be analyzed twice, but the second time various "internal checks" would be disabled to avoid emitting multiple diagnostics (e.g., "null dereference") for the same issue. The problem is that such checks also effect path pruning and don't just emit diagnostics. This resulted in an assertion failure involving a real divide-by-zero in some analyzed code where we would get an assertion failure in APInt because the 'DivZero' check was disabled and didn't prune the logic that resulted in the divide-by-zero in the analyzer. The implemented solution is somewhat of a hack, and may not perform extremely well. This will need to be cleaned up over time. As a regression test, 'misc-ps.m' has been modified so that its tests are run using -fobjc-gc to test this diagnostic pruning behavior. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82198 91177308-0d34-0410-b5e6-96231b3b80d8

2009-09-17Initial implementation of a code-completion interface in Clang. InDouglas Gregor
essence, code completion is triggered by a magic "code completion" token produced by the lexer [*], which the parser recognizes at certain points in the grammar. The parser then calls into the Action object with the appropriate CodeCompletionXXX action. Sema implements the CodeCompletionXXX callbacks by performing minimal translation, then forwarding them to a CodeCompletionConsumer subclass, which uses the results of semantic analysis to provide code-completion results. At present, only a single, "printing" code completion consumer is available, for regression testing and debugging. However, the design is meant to permit other code-completion consumers. This initial commit contains two code-completion actions: one for member access, e.g., "x." or "p->", and one for nested-name-specifiers, e.g., "std::". More code-completion actions will follow, along with improved gathering of code-completion results for the various contexts. [*] In the current -code-completion-dump testing/debugging mode, the file is truncated at the completion point and EOF is translated into "code completion". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82166 91177308-0d34-0410-b5e6-96231b3b80d8
