================
Comment at: clang/lib/Driver/ToolChains/Darwin.cpp:47
   // complete architecture list, nor a reasonable subset. The problem is that
-  // historically the driver driver accepts this and also ties its -march=
   // handling to the architecture name, so we need to be careful before removing

I think that's correct. IIRC, the "driver driver" was a feature in apple gcc long ago, and it was a driver that invoked the gcc driver once per `-arch` or some such. One of the early goals of clang was to just have a driver, but no driver driver.
