        <div>
        <pre>Opcodes with negative offset are decoded incorrectly - the offset value is
invalid. An example:

    0xff,0x4f,0x30,0xdc,0x00,0x00,0x02,0x05

Should be decoded as follows:

    scratch_load_dword v5, off, s2 offset:-1

Actual result is:

    scratch_load_dword v5, off, s2 offset:2047</pre>
