In ELF and COFF an alias is just another offset in a section. There is no way to represent an alias to something in another file. In MachO, the spec has the N_INDR type which should allow for exactly that, but is not currently implemented. Given that it is specified but not implemented, we error in codegen to avoid miscompiling but don't reject aliases to declarations in the verifier to leave the option open of implementing it. In the past we have used alias to declarations as a way of implementing weakref, which is why it exists in some old tests which this patch updates. llvm-svn: 194705
