Yes, clang doesn't have a module mapper. And I remember Iain said he want to introduce these options in GCC.
Thanks,

Subject:Re: Naming flag for specifying the output file name for Binary Module Interface files
I'm missing something from this discussion. IIUC the claim is that these 2 new
options -fmodule-output{,=NAME} are for build systems that want to specify the
module output file.
But how do they specify the mapping from module/header-unit name to CMI, so that
imports work?
Is this really a clang-specific mechanism, as it has no module mapper ATM (IIUC)?
