    55<p>The GCN1.0/1.1 delivers maximum 104 registers (with VCC). Basic list of destination
    66scalar operands have 128 entries. Source operands codes is in range 0-255.</p>
    7 <p><strong>Important</strong>: Two SGPR's must be aligned to 2. Four or more SGPR's must be aligned to 4.</p>
     7<p><strong>Important</strong>: Two SGPR's must be aligned to 2. Four or more SGPR's must be aligned to 4.
     8This rule do not apply to vector instruction where is more complex rule:
     9SGPR's can be unaligned only if SGPR register range do not cross line (4 SGPR registers).</p>
