of trying to generate the object file itself. If you can't arrange for your target's assembler to be in the right place and named `as` then you have two choices: (1) have Clang emit assembler source with the `-S` option and run the correct assembler directly;
(2) support your target more thoroughly in Clang's 'Driver' component, so that Clang knows what to do when you specify `-fno-integrated-as`.<o:p></o:p></span></a></p>
