vaddrΒΆ
This is an optional operand which may specify a 64-bit address, offset and/or index.
Size: 0, 1 or 2 dwords. Size is controlled by modifiers addr64, offen and idxen:
- If only addr64 is specified, this operand supplies a 64-bit address. Size is 2 dwords.
- If only idxen is specified, this operand supplies an index. Size is 1 dword.
- If only offen is specified, this operand supplies an offset. Size is 1 dword.
- If both idxen and offen are specified, index is in the first register and offset is in the second. Size is 2 dwords.
- If none of these modifiers are specified, this operand must be set to off.
- All other combinations of these modifiers are illegal.
