Hello, there is a question of vwadd intruction of SEW.
for example, There is a series of instructions here as follows: VSET(8,e8, m1); VLOAD_8(v2, ...); VLOAD_8(v4, ...); vwadd.wv v6, v2, v4;
I observed that ara will reshuffle v2 and then execute the vwadd command, which can be compared with Spike. However, if the vwadd.wv v6, v2, v4 instruction is replaced with vwadd.wv v6, v2, v2, because vs1==vs2, reshuffling will not be possible. This will cause the spike comparison to fail.,is this an issue with ARA?
