[FFmpeg-devel] [PATCH 3/3] lavc/svq1enc: R-V V ssd_int8_vs_int16

[Rémi Denis-Courmont]

+        vsetvli      t0, a2, e8, m2, tu, ma
+        vle8.v       v0, (a0)
+        sub          a2, a2, t0
+        vsetvli      zero, t0, e16, m4, tu, ma
+        vle16.v      v8, (a1)
+        vsetvli      zero, t0, e8, m2, tu, ma
+        vwsub.wv     v16, v8, v0
+        vsetvli      zero, t0, e16, m4, tu, ma

It looks to me like the second vsetvli is unnecessary, and consequently the 
third as well. As for the later ones, please use `vsetvli zero, zero` if you 
intend to change SEW while preserving VL and the LMUL:SEW ratio.
