I tried, but integrated-as was impractical due to too many possible
machine code matches for a given assembly statement.  So, the compiler
deals in pseudos and emits .s files.  If the integrated assembler
could accept an assembly string instead of an mcinst, I'd be in

Regardless, users could pass .s files on the command line and Clang
would still need to call llvm-mc with the right options.
