Even when the pipeline state section says a shader uses wave64, the instruction timing view prints the shader as wave32. This can be noticed when viewing VOPC or WMMA instructions.
For example, this if this was printed correctly, it would display vcc, not just vcc_lo.
35 v_cmp_lt_f32_e32 vcc_lo, v7, v8 1011 0.55 20 clk
