pub fn operand_format(opcode: u16) -> Option<OperandFormat>Expand description
The operand format of opcode (the opcode token’s low 11 bits, see opcode_name). None for
the opcodes without one: declarations, which Declared types, and call, callc, label and
interface_call, whose operands are not registers a program declares.
The table is the one vkd3d and DXVK both publish, with their counts agreeing for every opcode both list; where the
sources disagree on a type class it is OperandClass::Varies. umad, emitthencut, emitthencut_stream and
eval_snapped come from DXVK alone, and uaddc and usubb (two destinations and two sources) from Microsoft’s
instruction reference, since neither public table lists them.
