vaddr

This is an optional operand which may specify offset and/or index.

Size: 0, 1 or 2 dwords. Size is controlled by modifiers :ref:`offen<amdgpu_synid_offen>` and :ref:`idxen<amdgpu_synid_idxen>`:

• If only :ref:`idxen<amdgpu_synid_idxen>` is specified, this operand supplies an index. Size is 1 dword.
• If only :ref:`offen<amdgpu_synid_offen>` is specified, this operand supplies an offset. Size is 1 dword.
• If both modifiers 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 :ref:`off<amdgpu_synid_off>`.

Operands: :ref:`v<amdgpu_synid_v>`, :ref:`off<amdgpu_synid_off>`
