        <pre>Every LLVM IR function definition is required to contain at least one basic

block.  Every basic block is required to end with a terminator instruction. 

Thus every function contains at least one instruction.  There is no way to have

a "null function" at the IR level.  All kinds of places in LLVM (eg just about

every optimizer) depend on this invariant, so it isn't going to change.

Maybe you can have your inline asm take care of control flow itself, i.e. just

explicitly put the instructions that should be run at the end of the function

in the inline asm?  If there is an extraneous "ret" instruction following that

code, it should then be harmless.</pre>
