Actually, this code working now:

macro loadIdentifier(index, dest)
    loadp CodeBlock[cfr], t2
    loadp CodeBlock::m_unlinkedCode[t2], t1
    loadp UnlinkedCodeBlock::m_identifiers[t1], t2
    move t2, t1
    loadis index, t2
    mulp sizeof Identifier, t2
    addp t2, t1
    loadp Identifier::m_string[t1], dest
end

I would like to know if there is a way to test the changes in all architectures.
