| | | | | | | | warnings (warning or lack there of) as well since blocks are another pattern for envoking other designated initializers. // rdar://16323233 llvm-svn: 204081

* Sema: When merging objc string literals, give the result a constant array type.Benjamin Kramer2014-02-251-4/+8
| | | | | | | | Also assert that we never create non-array string literals again. PR18939. llvm-svn: 202147
* Rename getResultType() on function and method declarations to getReturnType()Alp Toker2014-01-251-51/+45
| | | | | | | | | | | | | | | A return type is the declared or deduced part of the function type specified in the declaration. A result type is the (potentially adjusted) type of the value of an expression that calls the function. Rule of thumb: * Declarations have return types and parameters. * Expressions have result types and arguments. llvm-svn: 200082
* [objc] Refactor and improve functionality for the -Wunused-property-ivar ↵Argyrios Kyrtzidis2014-01-031-5/+7
| | | | | | | | | | | | | | warning. - Remove the additions to ObjCMethodDecl & ObjCIVarDecl that were getting de/serialized and consolidate all functionality for the checking for this warning in Sema::DiagnoseUnusedBackingIvarInAccessor - Don't check immediately after the method body is finished, check when the @implementation is finished. This is so we can see if the ivar was referenced by any other method, even if the method was defined after the accessor. - Don't silence the warning if any method is called from the accessor silence it if the accessor delegates to another method via self. rdar://15727325 llvm-svn: 198432

* ObjectiveC. Remove false positive warning for missing propertyFariborz Jahanian2014-01-021-1/+3
| | | | | | | backing ivar by not issuing this warning if ivar is referenced somewhere and accessor makes method calls. // rdar://15727325 llvm-svn: 198367
* Support and use token kinds as diagnostic argumentsAlp Toker2013-12-241-1/+2
| | | | | | | | | | | | | | | | | | | Introduce proper facilities to render token spellings using the diagnostic formatter. Replaces most of the hard-coded diagnostic messages related to expected tokens, which all shared the same semantics but had to be multiply defined due to variations in token order or quote marks. The associated parser changes are largely mechanical but they expose commonality in whole chunks of the parser that can now be factored away. This commit uses C++11 typed enums along with a speculative legacy fallback until the transition is complete. Requires corresponding changes in LLVM r197895. llvm-svn: 197972
* Switched code from using hasAttr followed by getAttr to simply call getAttr ↵Aaron Ballman2013-12-191-2/+1

* Objective-C. Make diagnostics and fix-its consistent Fariborz Jahanian2013-12-171-0/+11
| | | | | | | | when diagnosing casting of a cstring literal to NSString in default and -fobjc-arc mode. // rdar://14106083 llvm-svn: 197515
* ObjectiveC. Further improvements of useFariborz Jahanian2013-12-161-13/+25
| | | | | | | | | | of objc_bridge_related attribute; eliminate unnecessary diagnostics which is issued elsewhere, fixit now produces a valid AST tree per convention. This results in some simplification in handling of this attribute as well. // rdar://15499111 llvm-svn: 197436

| | | | | | | | | | | super another initializer and when the implementation does not delegate to another initializer via a call on 'self'.
