--- Comment #11 from Jiri Slaby <jirislaby at gmail dot com> --- (In reply to Jakub Jelinek from comment #10) > If you are calling a function (__sw_hweight32) without letting gcc know you > do that, are you sure that function call does not modify any registers other > than "flags" and "rax"? Not at all, I suppose. See attachment #37552. __sw_hweight32 changes only retval (rax) and parameter (rdi). But __sw_hweight32 proper is as well instrumented by the coverage hook. And it changes whatever... In any way, what is the proper way of annotating asm() directive when there is a call inside?
