<pre>These instructions are decoded incorrectly in wavesize=32 mode. dst size is
invalid. An example:
0xf9,0x04,0x1e,0x7d,0x01,0xfb,0x06,0x06
Should be decoded as follows:
v_cmp_class_f16_sdwa ttmp15, v1, v2 src0_sel:DWORD src1_sel:DWORD
Actual result:
v_cmp_class_f16_sdwa ttmp[14:15], v1, v2 src0_sel:DWORD src1_sel:DWORD</pre>
