r199430 is to make possible to use TargetMachine information into IR passes.
To do that, yes, you have to specify a triple.
Nevertheless, The triple can be specified like for llc on either the command line or the file.
The triple was already in the file, so I didn’t add it on the command.
Sorry if it has confused you.

If you want to see what r199430 does, you can run this test with and without it and you will see that without it, codegenprepare is not doing anything on that test.

Does it help?

Thanks,
