Clang bugs

Links to reported bugs will be attached in future

• inside lambda, clang doesn’t include mutable (non-const) methods of current class even if ‘this’ was captured by lambda
  Bug: http://llvm.org/bugs/show_bug.cgi?id=15085
  See example, completion requested in point marked with ‘#’ sign

• Clang does not add virtual functions to proposals list
  

• no way to differ method definition and call with qualifier: completion strings and contexts are the same in both cases: http://llvm.org/bugs/show_bug.cgi?id=15745
  

Poor diagnostic for such code if C++11 disabled

• clang does not add classes to completion proposals when completing ‘foreach’

• when declaring variable, variable itself proposed with highest priority. It’s error.

• Macro completions not added after class keyword
  

• Wrong completions inside function-try-block in constructor: http://llvm.org/bugs/show_bug.cgi?id=15660
  

• Completion with nested names lookup not performed for comparison with enum value
  

• Value types completions added where thay shouldn’t be
  

• C++11 ‘override’ pseudo-keyword breaks clang_annotateTokens()
  

• Poor completion context recognition in template params
  

• Clang doesn’t add Informative completion chunk to macro. It better to add macro definition text to informative.
  

• Completion stops after asterisk:
  

• Macro trick used in GLEW library not handled by completion: http://llvm.org/bugs/show_bug.cgi?id=15631

• Completion results for function with optional arguments does not have default argument value: http://llvm.org/bugs/show_bug.cgi?id=14477
