--- Comment #9 from Josh Poimboeuf <jpoimboe at redhat dot com> --- I might be misunderstanding, but I don't think we need DRAP for our use case. We just need assurance that the frame pointer (RBP) has been set up before the inline asm is inserted. If clobbering "sp" isn't the right approach, maybe a new syntax, hopefully a documented one, would be better. Like a special "frame" clobber, for example.
