             Bug #: 13070
           Summary: missing namespace typo correction for switch on enum
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: richard-llvm at metafoo.co.uk
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


I got these diagnostics:

lib/Sema/SemaDeclCXX.cpp:3879:8: error: use of undeclared identifier
'CXXDefaultConstructor'
  case CXXDefaultConstructor:
       ^
lib/Sema/SemaDeclCXX.cpp:3880:8: error: use of undeclared identifier
'CXXCopyConstructor'
  case CXXCopyConstructor:
       ^
lib/Sema/SemaDeclCXX.cpp:3881:8: error: use of undeclared identifier
'CXXMoveConstructor'
  case CXXMoveConstructor:
       ^
lib/Sema/SemaDeclCXX.cpp:3884:8: error: use of undeclared identifier
'CXXCopyAssignment'
  case CXXCopyAssignment:
       ^
lib/Sema/SemaDeclCXX.cpp:3885:8: error: use of undeclared identifier
'CXXMoveAssignment'
  case CXXMoveAssignment:
       ^
lib/Sema/SemaDeclCXX.cpp:3886:8: error: use of undeclared identifier
'CXXDestructor'
  case CXXDestructor:
       ^
lib/Sema/SemaDeclCXX.cpp:3887:8: error: use of undeclared identifier
'CXXInvalid'
  case CXXInvalid:
       ^
lib/Sema/SemaDeclCXX.cpp:3878:11: warning: 7 enumeration values not handled in
switch: 'CXXDefaultConstructor', 'CXXCopyConstructor', 'CXXMoveConstructor'...
[-Wswitch]
  switch (CSM) {
          ^

There's no hint here what's wrong, just some mutually contradictory
diagnostics. We should be able to do better here, and typo-correct to
'Sema::CXXDefaultConstructor' etc. Ideally, I'd like to see only one diagnostic
for this (with all the fixits attached, for clients that care about that sort
of thing).
