2013-03-04Comment parsing: refactor handling of command markers in ASTDmitri Gribenko
* Use the term 'command marker', because the semantics of 'backslash' and 'at' commands are the same. (Talking about 'at commands' makes them look like a special entity.) * Sink the flag down into bitfields, reducing the size of AST nodes. * Change the flag into an enum for clarity. Boolean function parameters are not very clear. * Add unittests for new tok::at_command tokens. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@176461 91177308-0d34-0410-b5e6-96231b3b80d8

This also gives us 0.2% speedup on '-fsyntax-only -Wdocumentation' time for a testcase that consists of all Clang headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@174810 91177308-0d34-0410-b5e6-96231b3b80d8

2012-12-19Comment parsing: add a missing 'else'. Found by inspection.Dmitri Gribenko
No testcase because we were just building an extra AST node and eventually throwing it away, so it did not affect correctness. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@170563 91177308-0d34-0410-b5e6-96231b3b80d8
2012-12-04Sort all of Clang's files under 'lib', and fix up the broken headersChandler Carruth
uncovered. This required manually correcting all of the incorrect main-module headers I could find, and running the new llvm/utils/sort_includes.py script over the files. I also manually added quite a few missing headers that were uncovered by shuffling the order or moving headers up to be main-module-headers. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@169237 91177308-0d34-0410-b5e6-96231b3b80d8
2012-11-18Documentation parsing: propely handle a lone '\endverbatim' and emit a warning.Dmitri Gribenko
We actually used to assert on this. Thanks to NAKAMURA Takumi for noticing this! git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@168277 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-11Comment parsing: handle non-builtin commands correctly. After semanticDmitri Gribenko
analysis registers a command, it becomes a "known" command for the lexer, since it has an ID. Having this freedom of choice to register a command is a good thing since BriefParser does not need this. But the parser should still invoke the correct semantic analysis method (actOnUnknownCommand) in this case. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163646 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-10Comment AST: TableGen'ize all command lists in CommentCommandTraits.cpp.Dmitri Gribenko
Now we have a list of all commands. This is a good thing in itself, but it also enables us to easily implement typo correction for command names. With this change we have objects that contain information about each command, so it makes sense to resolve command name just once during lexing (currently we store command names as strings and do a linear search every time some property value is needed). Thus comment token and AST nodes were changed to contain a command ID -- index into a tables of builtin and registered commands. Unknown commands are registered during parsing and thus are also uniformly assigned an ID. Using an ID instead of a StringRef is also a nice memory optimization since ID is a small integer that fits into a common bitfield in Comment class. This change implies that to get any information about a command (even a command name) we need a CommandTraits object to resolve the command ID to CommandInfo*. Currently a fresh temporary CommandTraits object is created whenever it is needed since it does not have any state. But with this change it has state -- new commands can be registered, so a CommandTraits object was added to ASTContext. Also, in libclang CXComment has to be expanded to include a CXTranslationUnit so that all functions working on comment AST nodes can get a CommandTraits object. This breaks binary compatibility of CXComment APIs. Now clang_FullComment_getAsXML(CXTranslationUnit TU, CXComment CXC) doesn't need TU parameter anymore, so it was removed. This is a source-incompatible change for this C API. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163540 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-31Comment parsing: add support for \tparam command on all levels.Dmitri Gribenko
The only caveat is renumbering CXCommentKind enum for aesthetic reasons -- this breaks libclang binary compatibility, but should not be a problem since API is so new. This also fixes PR13372 as a side-effect. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@161087 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-20Fix PR13411: Comment parsing: failed assertion on unterminated verbatim block.Dmitri Gribenko
The assertion was wrong in case we have a verbatim block without a closing command. Also add tests for closing command name in a verbatim block, since now it can be empty in such cases. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160568 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-11Enable comment parsing and semantic analysis to emit diagnostics. A fewDmitri Gribenko
diagnostics implemented -- see testcases. I created a new TableGen file for comment diagnostics, DiagnosticCommentKinds.td, because comment diagnostics don't logically fit into AST diagnostics file. But I don't feel strongly about it. This also implements support for self-closing HTML tags in comment lexer and parser (for example, <br />). In order to issue precise diagnostics CommentSema needs to know the declaration the comment is attached to. There is no easy way to find a decl by comment, so we match comments and decls in lockstep: after parsing one declgroup we check if we have any new, not yet attached comments. If we do -- then we do the usual comment-finding process. It is interesting that this automatically handles trailing comments. We pick up not only comments that precede the declaration, but also comments that *follow* the declaration -- thanks to the lookahead in the lexer: after parsing the declgroup we've consumed the semicolon and looked ahead through comments. Added -Wdocumentation-html flag for semantic HTML errors to allow the user to disable only HTML warnings (but not HTML parse errors, which we emit as warnings in -Wdocumentation). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@160078 91177308-0d34-0410-b5e6-96231b3b80d8

2012-07-06Implement AST classes for comments, a real parser for Doxygen comments and aDmitri Gribenko
very simple semantic analysis that just builds the AST; minor changes for lexer to pick up source locations I didn't think about before. Comments AST is modelled along the ideas of HTML AST: block and inline content. * Block content is a paragraph or a command that has a paragraph as an argument or verbatim command. * Inline content is placed within some block. Inline content includes plain text, inline commands and HTML as tag soup. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@159790 91177308-0d34-0410-b5e6-96231b3b80d8
