[PATCH] D81785: [clangd] Fix readability-else-after-return 'Adding a note without main diagnostic' crash

[Nathan James via Phabricator via cfe-commits]

njames93 added a comment.

The actual fix in `ElseAfterReturnCheck.cpp` is needed. 
However clangd's handling of Remarks is a little suspicious. Remarks are 
supposed to be different to notes in the sense they are designed to be stand 
alone, unlike notes which depend on a another diagnostic. see Add 'remark' 
diagnostic type in 'clang' 
<https://github.com/llvm/llvm-project/commit/741602461d2079c682916bce6701c39acb08bbd3>
This seems to be how clangd determines what a note is:

  bool isNote(DiagnosticsEngine::Level L) {
    return L == DiagnosticsEngine::Note || L == DiagnosticsEngine::Remark;
  }
