<pre>GFX1030 does not support v_mac_f32 instruction. However assembler triggers no
errors for dpp variants of this instruction:
// Assembled w/o errors!
v_mac_f32 v5, v1, v2 dpp8:[7,6,5,4,3,2,1,0]
v_mac_f32_dpp v5, v1, v2 quad_perm:[3,2,1,0] row_mask:0x0 bank_mask:0x0
Other variants of v_mac_f32 are rejected as expected.</pre>
