It seems the upstream llvm-project/flang link that you are pointing to here refers to `getModel<c_float_complex_t>()`. You can see that the fir-dev branch also uses `fir::ComplexType` for this function. It is for `getModel<std::complex<float>>()` that fir-dev uses `mlir::ComplexType()`.

Regarding your question, I guess the FIR core team can provide an authoritative answer.
