Hi All, I am looking at a linker error under O2: undefined symbol __lshrdi3 I have two questions here: 1. Does that mean our libgcc (?) doesn't implement __lshrdi3? Or more generally, why I have such linker error? 2. Seems some operations are combined, and replaced with __lshrdi3 call. I am interested in when such libcall will be generated? Could you show me one
