Aaron Ballman	99bfe26a1e	Add a C2x spelling for the external_source_symbol and internal_linkage attributes in the clang vendor namespace. ... Both of these attributes have existing meaning in C code, so there was no reason to exclude them from using the new spelling. llvm-svn: 326053	2018-02-25 14:43:45 +00:00
Aaron Ballman	adf66b6174	Determine the attribute subject for diagnostics based on declarative information in DeclNodes.td. This greatly reduces the number of enumerated values used for more complex diagnostics; these are now only required when the "attribute only applies to" diagnostic needs to be generated manually as part of semantic processing. ... This also clarifies some terminology used by the diagnostic (methods -> Objective-C methods, fields -> non-static data members, etc). Many of the tests needed to be updated in multiple places for the diagnostic wording tweaks. The first instance of the diagnostic for that attribute is fully specified and subsequent instances cut off the complete list (to make it easier if additional subjects are added in the future for the attribute). llvm-svn: 319002	2017-11-26 20:01:12 +00:00
Evgeniy Stepanov	ae6ebd3af5	Implement __attribute__((internal_linkage)). ... The attrubite is applicable to functions and variables and changes the linkage of the subject to internal. This is the same functionality as C-style "static", but applicable to class methods; and the same as anonymouns namespaces, but can apply to individual methods of a class. Following the proposal in http://lists.llvm.org/pipermail/cfe-dev/2015-October/045580.html llvm-svn: 252648	2015-11-10 21:28:44 +00:00
