--- Comment #6 from Marc Glisse <glisse at gcc dot gnu.org> --- I am only learning now that bit ops don't exist for complex numbers :-/ I don't really see why not, but that's a different question. Thanks for fixing this. Looking to see if I could quickly find other similar issues, I only noticed 2 ICEs typedef _Complex unsigned T; T f(T x){ return (x/2)*2; } T g(T x){ return (x*2)/2; }
