--- Comment #4 from Konstantin Serebryany <konstantin.s.serebryany at gmail dot com> 2012-11-27 17:52:02 UTC --- For what purpose would any one avoid longjmp call, other than for performance? Under asan, performance already drops by 2x, so using calls will not hurt much. Of course, we could instrument __builtin_longjmp call in the compiler module, but is it worth it? If yes, all we need is to call __asan_handle_no_return before __builtin_longjmp
