Hi, thanks for looking into this.

Only the verifier pass is invoked twice. You can see this using `bbc --mlir-pass-statistics`.

I don't think this is the right fix. This patch would cause the verifier pass not to be run at all when `-emit-hlfir` is used. I think you should bring the second `pm.run(mlirModule)` out of the if statement.
