[PATCH V2] RISC-V: Support one more overlap for wv instructions

2023-12-18 Thread Juzhe-Zhong
For 'wv' instructions, e.g. vwadd.wv vd,vs2,vs1. vs2 has same EEW as vd. vs1 has smaller than vd. So, vs2 can overlap with vd, but vs1 can only overlap highest-number of vd when LMUL of vs1 is greater than 1. We already have supported overlap for vs1 LMUL >= 1. But I forget vs1 LMUL < 1, vs2
