Hi Meador, that is precisely the point of these changes. :)

My next change it to use this API in Clang, to replace mfpu / march
options. I think there will be a lot missing that Clang accepts and
the assembler doesn't. But that's where we need to come with a common
approach, so both can support all choices (where valid).

cheers,
