2009-11-10Improve parsing of template arguments to lay the foundation forDouglas Gregor
handling template template parameters properly. This refactoring: - Parses template template arguments as id-expressions, representing the result of the parse as a template name (Action::TemplateTy) rather than as an expression (lame!). - Represents all parsed template arguments via a new parser-specific type, ParsedTemplateArgument, which stores the kind of template argument (type, non-type, template) along with all of the source information about the template argument. This replaces an ad hoc set of 3 vectors (one for a void*, which was either a type or an expression; one for a bit telling whether the first was a type or an expression; and one for a single source location pointing at the template argument). - Moves TemplateIdAnnotation into the new Parse/Template.h. It never belonged in the Basic library anyway. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86708 91177308-0d34-0410-b5e6-96231b3b80d8
2009-11-05Make LookUpIdentifierInfo const. This makes the Identifiers table mutable and isDaniel Dunbar
a little fuzzy, but conceptually it's just uniquing the identifier. Chris, please review. I debated splitting into const/non-const versions where the const one propogated constness to the resulting IdentifierInfo*. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@86106 91177308-0d34-0410-b5e6-96231b3b80d8

operators, e.g., operator+<int> which now works in declarators, id-expressions, and member access expressions.

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

2009-07-22Change Preprocessor to keep a copy of LangOptions instead of reference, like ↵Argyrios Kyrtzidis
ASTContext. Now when creating a Preprocessor we can pass it a temporary LangOptions object instead of having to remember to keep it around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@76815 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
2009-06-14Update LLVM.Douglas Gregor
Implement support for C++ Substitution Failure Is Not An Error (SFINAE), which says that errors that occur during template argument deduction do *not* produce diagnostics and do not necessarily make a program ill-formed. Instead, template argument deduction silently fails. This is currently implemented for template argument deduction during matching of class template partial specializations, although the mechanism will also apply to template argument deduction for function templates. The scheme is simple: - If we are in a template argument deduction context, any diagnostic that is considered a SFINAE error (or warning) will be suppressed. The error will be propagated up the call stack via the normal means. - By default, all warnings and errors are SFINAE errors. Add the NoSFINAE class to a diagnostic in the .td file to make it a hard error (e.g., for access-control violations). Note that, to make this fully work, every place in Sema that emits an error *and then immediately recovers* will need to check Sema::isSFINAEContext() to determine whether it must immediately return an error rather than recovering. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73332 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-14Sink the BuiltinInfo object from ASTContext into theChris Lattner
preprocessor and initialize it early in clang-cc. This ensures that __has_builtin works in all modes, not just when ASTContext is around. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73319 91177308-0d34-0410-b5e6-96231b3b80d8
2009-06-13implement and document a new __has_feature and __has_builtin magic Chris Lattner
builtin preprocessor macro. This appears to work with two caveats: 1) builtins are registered in -E mode, and 2) target-specific builtins are unconditionally registered even if they aren't supported by the target (e.g. SSE4 builtin when only SSE1 is enabled). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@73289 91177308-0d34-0410-b5e6-96231b3b80d8

2009-04-14Change Lexer::MeasureTokenLength to take a LangOptions reference.Chris Lattner

2009-04-10Compare the predefines buffer in the PCH file with the predefinesDouglas Gregor
buffer generated for the current translation unit. If they are different, complain and then ignore the PCH file. This effectively checks for all compilation options that somehow would affect preprocessor state (-D, -U, -include, the dreaded -imacros, etc.). When we do accept the PCH file, throw away the contents of the predefines buffer rather than parsing them, since all of the results of that parsing are already stored in the PCH file. This eliminates the ugliness with the redefinition of __builtin_va_list, among other things. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@68838 91177308-0d34-0410-b5e6-96231b3b80d8
