[LLVMdev] newbie qustion: how to generate machine code for target thumb?

writing object code directly is not supported yet (though it is being worked
on), so for the moment you should not use "-filetype obj".  Without this option
llc will generate assembler, which you will need to assemble using an
appropriate assembler.
