2013-03-26[ms-cxxabi] Give the MS inheritance attributes a base classReid Kleckner
Required making a handful of changes to the table generator. Also adds an unspecified inheritance attribute. This opens the path for us to apply these attributes to C++ records implicitly. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@178054 91177308-0d34-0410-b5e6-96231b3b80d8

2013-01-24PR14922: when printing an attribute, use the real syntax of the attribute ↵Michael Han
(GNU, C++11, MS Declspec) instead of hardcoded GNU syntax. Introduce a spelling index to Attr class, which is an index into the attribute spelling list of an attribute defined in Attr.td. This index will determine the actual spelling used by an attribute, as it incorporates both the syntax and naming of the attribute. When constructing an attribute AST node, the spelling index is computed based on attribute kind, scope (if it's a C++11 attribute), and name, then passed to Attr that will use the index to print itself. Thanks to Richard Smith for the idea and review. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@173358 91177308-0d34-0410-b5e6-96231b3b80d8

The declarations of the operators no longer matched. The definitions in ASTContext.h had 'throw()' removed, but it was still present in Attr.h. Somehow the buildbots missed this. clang merely warns about a missing 'throw()' specification and suggested a Fix-It adding it back, but gcc 4.5 is not so forgiving and gives an error. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@152167 91177308-0d34-0410-b5e6-96231b3b80d8

2011-03-23Implement a new 'availability' attribute, that allows one to specifyDouglas Gregor
which versions of an OS provide a certain facility. For example, void foo() __attribute__((availability(macosx,introduced=10.2,deprecated=10.4,obsoleted=10.6))); says that the function "foo" was introduced in 10.2, deprecated in 10.4, and completely obsoleted in 10.6. This attribute ties in with the deployment targets (e.g., -mmacosx-version-min=10.1 specifies that we want to deploy back to Mac OS X 10.1). There are several concrete behaviors that this attribute enables, as illustrated with the function foo() above: - If we choose a deployment target >= Mac OS X 10.4, uses of "foo" will result in a deprecation warning, as if we had placed attribute((deprecated)) on it (but with a better diagnostic) - If we choose a deployment target >= Mac OS X 10.6, uses of "foo" will result in an "unavailable" warning (in C)/error (in C++), as if we had placed attribute((unavailable)) on it - If we choose a deployment target prior to 10.2, foo() is weak-imported (if it is a kind of entity that can be weak imported), as if we had placed the weak_import attribute on it. Naturally, there can be multiple availability attributes on a declaration, for different platforms; only the current platform matters when checking availability attributes. The only platforms this attribute currently works for are "ios" and "macosx", since we already have -mxxxx-version-min flags for them and we have experience there with macro tricks translating down to the deprecated/unavailable/weak_import attributes. The end goal is to open this up to other platforms, and even extension to other "platforms" that are really libraries (say, through a #pragma clang define_system), but that hasn't yet been designed and we may want to shake out more issues with this narrower problem first. Addresses <rdar://problem/6690412>. As a drive-by bug-fix, if an entity is both deprecated and unavailable, we only emit the "unavailable" diagnostic. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@128127 91177308-0d34-0410-b5e6-96231b3b80d8

2011-01-21Generalise support for non-inheritable attributesPeter Collingbourne
Inheritable attributes on declarations may be inherited by any later redeclaration at merge time. By contrast, a non-inheritable attribute will not be inherited by later redeclarations. Non-inheritable attributes may be semantically analysed early, allowing them to influence the redeclaration/overloading process. Before this change, the "overloadable" attribute received special handling to be treated as non-inheritable, while all other attributes were treated as inheritable. This patch generalises the concept, while removing a FIXME. Some CUDA location attributes are also marked as non-inheritable in order to support special overloading semantics (to be introduced in a later patch). The patch introduces a new Attr subclass, InheritableAttr, from which all inheritable attributes derive. Non-inheritable attributes simply derive from Attr. N.B. I did not review every attribute to determine whether it should be marked non-inheritable. This can be done later on an incremental basis, as this change does not affect default functionality. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@123959 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-18Generate Attr subclasses with TableGen.Sean Hunt
Now all classes derived from Attr are generated from TableGen. Additionally, Attr* is no longer its own linked list; SmallVectors or Attr* are used. The accompanying LLVM commit contains the updates to TableGen necessary for this. Some other notes about newly-generated attribute classes: - The constructor arguments are a SourceLocation and a Context&, followed by the attributes arguments in the order that they were defined in Attr.td - Every argument in Attr.td has an appropriate accessor named getFoo, and there are sometimes a few extra ones (such as to get the length of a variadic argument). Additionally, specific_attr_iterator has been introduced, which will iterate over an AttrVec, but only over attributes of a certain type. It can be accessed through either Decl::specific_attr_begin/end or the global functions of the same name. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@111455 91177308-0d34-0410-b5e6-96231b3b80d8

2010-06-25Implement dependent alignment attribute support. This is a bit gross given theChandler Carruth
current attribute system, but it is enough to handle class templates which specify parts of their alignment in terms of their template parameters.

2010-06-16Implement first TD-based usage of attributes.Sean Hunt
Currently, there are two effective changes: - Attr::Kind has been changed to attr::Kind, in a separate namespace rather than the Attr class. This is because the enumerator needs to be visible to parse. - The class definitions for the C++0x attributes other than aligned are generated by TableGen. The specific classes generated by TableGen are controlled by an array in TableGen (see the accompanying commit to the LLVM repository). I will be expanding the amount of code generated as I develop the new attributes system while initially keeping it confined to these attributes. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@106172 91177308-0d34-0410-b5e6-96231b3b80d8
