<div>
<pre>VOP3 instructions do not check register size for operands with modifiers. The
following code should trigger errors, but it is assembled without any issues:
v_add_f32 v0, s[0:1], v0 // src0 should be a 32-bit register
v_add_f32 v0, v[0:1], v0 // src0 should be a 32-bit register
v_add_f64 v[0:1], s0, v[0:1] // src0 should be a 64-bit register
v_add_f64 v[0:1], v0, v[0:1] // src0 should be a 64-bit register</pre>
</div>
