    How to add an attribute

    + +

    To add an attribute, you'll have to add it to the list of attributes, add it +to the parsing phase, and look for it in the AST scan. +r124217 +has a good example of adding a warning attribute.

    + +

    (Beware that this hasn't been reviewed/fixed by the people who designed the +attributes system yet.)

    + +

    include/clang/Basic/Attr.td

    + +

    Each attribute gets a def inheriting from Attr or one of +its subclasses. InheritableAttr means that the attribute also applies +to subsequent declarations of the same name.

    + +

    Spellings lists the strings that can appear in +__attribute__((here)) or [[here]]. All such strings +will be synonymous. If you want to allow the [[]] C++0x +syntax, you have to define a list of Namespaces, which will +let users write [[namespace:spelling]]. Using the empty +string for a namespace will allow users to write just the spelling +with no ":".

    + +

    Subjects restricts what kinds of AST node to which this attribute +can appertain (roughly, attach).

    + +

    Args names the arguments the attribute takes, in order. If +Args is [StringArgument<"Arg1">, IntArgument<"Arg2">] +then __attribute__((myattribute("Hello", 3))) will be a valid use.

    + +

    Boilerplate

    + +

    Add an element to the AttributeList::Kind enum in include/clang/Sema/AttributeList.h +named AT_lower_with_underscores. That is, a CamelCased +AttributeName in Attr.td name should become +AT_attribute_name.

    + +

    Add a case to the StringSwitch in AttributeList::getKind() +in lib/Sema/AttributeList.cpp +for each spelling of your attribute. Less common attributes should come toward +the end of that list.

    + +

    Write a new HandleYourAttr() function in lib/Sema/SemaDeclAttr.cpp, +and add a case to the switch in ProcessNonInheritableDeclAttr() or +ProcessInheritableDeclAttr() forwarding to it.

    + +

    If your attribute causes extra warnings to fire, define a DiagGroup +in include/clang/Basic/DiagnosticGroups.td +named after the attribute's Spelling with "_"s replaced by "-"s. If +you're only defining one diagnostic, you can skip DiagnosticGroups.td +and use InGroup<DiagGroup<"your-attribute">> directly in DiagnosticSemaKinds.td

    + +

    The meat of your attribute

    + +

    Find an appropriate place in Clang to do whatever your attribute needs to do. +Check for the attribute's presence using Decl::getAttr<YourAttr>().

    + +

    Update the Clang Language Extensions +document to describe your new attribute.

        Objective-C retaining behavior attributes

        + +

        In Objective-C, functions and methods are generally assumed to take +and return objects with +0 retain counts, with some exceptions for +special methods like +alloc and init. However, +there are exceptions, and so Clang provides attributes to allow these +exceptions to be documented, which helps the analyzer find leaks (and +ignore non-leaks).

        + +

        Usage: The ns_returns_retained, ns_returns_not_retained, +ns_returns_autoreleased, cf_returns_retained, +and cf_returns_not_retained attributes can be placed on +methods and functions that return Objective-C or CoreFoundation +objects. They are commonly placed at the end of a function prototype +or method declaration:

        + +
        +  id foo() __attribute__((ns_returns_retained));
+
+  - (NSString*) bar: (int) x __attribute__((ns_returns_retained));
+
        + +

        The *_returns_retained attributes specify that the +returned object has a +1 retain count. +The *_returns_not_retained attributes specify that the return +object has a +0 retain count, even if the normal convention for its +selector would be +1. ns_returns_autoreleased specifies that the +returned object is +0, but is guaranteed to live at least as long as the +next flush of an autorelease pool.

        + +

        Usage: The ns_consumed and cf_consumed +attributes can be placed on an parameter declaration; they specify +that the argument is expected to have a +1 retain count, which will be +balanced in some way by the function or method. +The ns_consumes_self attribute can only be placed on an +Objective-C method; it specifies that the method expects +its self parameter to have a +1 retain count, which it will +balance in some way.
