I am confused since the output `[[PREFIX]]/impl_part.o` is the same with `P1689` output `[[PREFIX]]/impl_part.o` and the one in the compilation database and the one specified in the command line option `--p1689-targeted-output`. What's the expected output for you in this case? (and the related command line input.)
