2009-09-22Replace the -code-completion-dump option with Douglas Gregor
-code-completion-at=filename:line:column which performs code completion at the specified location by truncating the file at that position and enabling code completion. This approach makes it possible to run multiple tests from a single test file, and gives a more natural command-line interface. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@82571 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

2009-07-02Add support for retrieving the Doxygen comment associated with a givenDouglas Gregor
declaration in the AST. The new ASTContext::getCommentForDecl function searches for a comment that is attached to the given declaration, and returns that comment, which may be composed of several comment blocks. Comments are always available in an AST. However, to avoid harming performance, we don't actually parse the comments. Rather, we keep the source ranges of all of the comments within a large, sorted vector, then lazily extract comments via a binary search in that vector only when needed (which never occurs in a "normal" compile). Comments are written to a precompiled header/AST file as a blob of source ranges. That blob is only lazily loaded when one requests a comment for a declaration (this never occurs in a "normal" compile). The indexer testbed now supports comment extraction. When the -point-at location points to a declaration with a Doxygen-style comment, the indexer testbed prints the associated comment block(s). See test/Index/comments.c for an example. Some notes: - We don't actually attempt to parse the comment blocks themselves, beyond identifying them as Doxygen comment blocks to associate them with a declaration. - We won't find comment blocks that aren't adjacent to the declaration, because we start our search based on the location of the declaration. - We don't go through the necessary hops to find, for example, whether some redeclaration of a declaration has comments when our current declaration does not. Similarly, we don't attempt to associate a \param Foo marker in a function body comment with the parameter named Foo (although that is certainly possible). - Verification of my "no performance impact" claims is still "to be done". git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@74704 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-23Fix our check for "random whitespace between a \ and newline" to workChris Lattner
with dos style newlines. I have a trivial test for this: // RUN: clang-cc %s -verify #define test(x, y) \ x ## y but I don't know how to get svn to not change newlines and testrunner doesn't work with dos style newlines either, so "not worth it". :) rdar://6994000 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73945 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-18Fix a crash that can occur when a #pragma handler eats to the end of theChris Lattner
line, and when the pragma is at the end of a file. In this case, the last token consumed could pop the lexer, invalidating CurPPLexer. Thanks to Peter Thoman for pointing it out. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73689 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-16my refactoring of builtins changed target-specific builtins to only beChris Lattner

This fixes the build of apps that use PCH and target specific builtins together. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73492 91177308-0d34-0410-b5e6-96231b3b80d8

2009-06-13implement and document a new __has_feature and __has_builtin magic Chris Lattner
builtin preprocessor macro.
