Example
For the example assembly code from the attachment, AsmParser emits reference to
A instead of X. Since ELF doesn't support relocations in symbol table, the
resulting value is incorrect (absolute zero).
GAS, on the other hand, references X with the corresponding offset. And if
definition of A is too complex, there's an error (llvm-mc is happy to accept
any definition but its value will obviously be incorrect).</pre>
