<br>
       void* foobitize(void thunk(void*,void*));<br>
<br>
How do I defined the intrinsic in llvm/IR/Intrinsics.td ?  It looks like I need to define a new class, but I'm lost about what I need to do.  There doesn't seem to be any prior examples of intrinsics that take pointers to routines.<br>

This not something I'm planning to submit as a commit; it's just part of an experiment.<br></blockquote><div><br></div><div>I think there are some intrinsics which just take llvm_ptr_ty and require their callers to bitcast to i8*.</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
