# Test multi-cycle VOPD formation constraints
# When OpX is a DPMACC instruction (multi-cycle) and OpX writes to
# OpY's source registers, VOPD formation is blocked. OpX must come second in
# original program order, or this would otherwise be a regular data dependency.
# This applies to:
# V_FMA_F64, V_ADD_F64, V_MUL_F64, V_MAX_NUM_F64, V_MIN_NUM_F64
