David Majnemer 475b25eefa AST: Don't ignore alignas on EnumDecls when calculating alignment
We didn't consider any alignment attributes on an EnumDecl when
calculating alignment.

While we are here, ignore alignment specifications on typedef types if
one is used as the underlying type.  Otherwise, weird things happen:

enum Y : int;
Y y;

typedef int __attribute__((aligned(64))) u;
enum Y : u {};

What is the alignment of 'Y'?  It would be more consistent with the
overall design of enums with fixed underlying types to consider the
underlying type's UnqualifiedDesugaredType.

This fixes PR22279.

dcl.attr.depend
dcl.attr.deprecated [c++1z] Support [[deprecated]] attributes on namespaces. Note that it only applies to situations where the namespace is mentioned. Thus, use on anonymous namespaces is diagnosed. 2014-11-14 22:34:56 +00:00
dcl.attr.grammar
dcl.attr.noreturn Adding the Subjects entry back for the noreturn attributes. This caused some test cases to be updated because the original diagnostic was about applying to methods as well as functions, but the semantic checking disallowed methods. 2013-11-27 18:53:58 +00:00
