--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> --- That looks like a binutils bug to me. When gcc is emitting the DW_AT_const_value, it doesn't know if it is signed or unsigned, CONST_INT it uses is always signed. So it emits .sleb128 -9223372036854775808 # DW_AT_const_value for it. That sleb128 value is certainly not too large, it fits into 64-bit signed value, and then the producers should interpret it (because the variable has unsigned rather than signed type) by casting it to unsigned 64-bit.
