<div>
<pre>Constant expressions started with "-" followed by a symbol are evaluated
incorrectly when used with VOP opcodes. In these cases the "-" sign is simply
ignored.
For example, the sequence
.set foo, 1
v_mul_f32 v0, -foo+2, v2 // -foo+2 = 1?
results in the same code as the following:
v_mul_f32 v0, 3, v2</pre>
