Dmitri Gribenko a43ec186a4 Attaching comments to declarations: find comment attached to any redeclaration
Not only look for the comment near the declaration itself, but also walk the
redeclaration chain: the previous declaration might have had a documentation
comment.

Dmitri Gribenko 5e4fe00e64 Add libclang APIs to walk comments ASTs and an API to convert a comment to an
HTML fragment.

For testing, c-index-test now has even more output:
* HTML rendering of a comment
* comment AST tree dump in S-expressions like Comment::dump(), but implemented
* with libclang APIs.

Argyrios Kyrtzidis 6d7833f1b6 Introduce a flag in SourceManager to treat non-system source files
as "volatile", meaning there's a high enough chance that they may
change while we are trying to use them.

This flag is only enabled by libclang.
Currently "volatile" source files will be stat'ed immediately
before opening them, because the file size stat info
may not be accurate since when we got it (e.g. from the PCH).
This avoids crashes when trying to reference mmap'ed memory
from a file whose size is not what we expect.

Note that there's still a window for a racing issue to occur
but the window for it should be way smaller than before.
We can consider later on to avoid mmap completely on such files.

Dmitri Gribenko 3292d06a1b Add a new libclang completion API to get brief documentation comment that is
attached to a declaration in the completion string.

Since extracting comments isn't free, a new code completion option is
introduced.

A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

Argyrios Kyrtzidis 091b87bb9d [libclang] When doing the cursor visitation make sure declarations
in the same line do not override getting a cursor for the previous declaration.

e.g:

int x, y;
@synthesize prop1, prop2;

pointing at 'x'/'prop1' would give 'y'/'prop2' because their source ranges overlap.

Argyrios Kyrtzidis 17dddd21f5 [libclang] Make sure that when we have multiple @class references in the same line,
that later ones do not override the previous ones.

If we have:
   @class Foo, Bar;

'Foo' even though the cursor location was at 'Foo'.

selector identifier in an objc method or message expression, and which selector index it is.

objc methods and objc message expressions, there are multiple pieces for each

Argyrios Kyrtzidis ab468b0381 Add info to ObjCPropertyRefExpr to indicate whether the dot syntax property
reference is going to message the setter, the getter, or both.

Having this info on the ObjCPropertyRefExpr node makes it easier for AST
clients (like libclang) to reason about the meaning of the property reference.

[AST/Sema]
-Use 2 bits (with a PointerIntPair) in ObjCPropertyRefExpr to record the above info
-Have ObjCPropertyOpBuilder set the info appropriately.

[libclang]
-When there is an implicit property reference (property syntax using methods)
have clang_getCursorReferenced return a cursor for the method. If the property
reference is going to result in messaging both the getter and the setter choose
to return a cursor for the setter because it is less obvious from source inspection
that the setter is getting called.

The general idea has the seal of approval by John.

Daniel Dunbar 62ee6417ac [AST/Sema/libclang] Replace getSourceRange().getBegin() with getLocStart().
- getSourceRange().getBegin() is about as awesome a pattern as .copy().size().

Argyrios Kyrtzidis 4a280ff48f [PCH] Mark a PCH file with a flag to indicate if the serialized AST had
compiler errors or not.

-Control whether ASTReader should reject such a PCH by a boolean flag at ASTReader's creation time.
By default, such a PCH file will be rejected with an error when trying to load it.

[libclang] Allow clang_saveTranslationUnit to create a PCH file even if compiler errors
occurred.
-Have libclang API calls accept a PCH that had compiler errors.

The general idea is that we want libclang to stay functional even if a PCH had a compiler error.

Douglas Gregor 29c42f2a25 Implement a new type trait __is_trivially_constructible(T, Args...)
that provides the behavior of the C++11 library trait
std::is_trivially_constructible<T, Args...>, which can't be
implemented purely as a library.

Since __is_trivially_constructible can have zero or more arguments, I
needed to add Yet Another Type Trait Expression Class, this one
handling arbitrary arguments. The next step will be to migrate
UnaryTypeTrait and BinaryTypeTrait over to this new, more general
TypeTrait class.

2012-02-16 11:35:52 +00:00
Sebastian Redl 86fab844bb Make CXXNewExpr contain only a single initialier, and not hold the used constructor itself.
Holding the constructor directly makes no sense when list-initialized arrays come into play. The constructor is now held in a CXXConstructExpr, if construction is what is done. The new design can also distinguish properly between list-initialization and direct-initialization, as well as implicit default-initialization constructors and explicit value-initialization constructors. Finally, doing it this way removes redundance from the AST because CXXNewExpr doesn't try to handle both the allocation and the initialization responsibilities.

This breaks the static analysis of new expressions. I've filed PR12014 to track this.
