By using the Release 20210816 with LLVM 13.0.0 RC1 · mstorsjo/llvm-mingw (github.com) I created a LLVM MinGW Qt 5.15.2 kit which I used to build and debug Qt Creator.

At first glance it looked like the Kit was usable in Qt Creator to debug Qt Creator itself, but then I've encountered an issue where the debugged Qt Creator disappears, due to a lldb.exe crash.

In the Debuggers settings lldb.exe has a "x86-windows-msvc2015-pe-64bit" entry for ABIs, and in the crash of the debugger log I can see:

 eERROR: Lldb stderr:  #0 0x00007ffab4913933 clang::CreateMicrosoftCXXABI(clang::ASTContext&) (C:\llvm-mingw\bin\libclang-cpp.dll+0x563933)
