  "message": "[RISCV] Rewrite vrgather.vx undef, (vmv.s.x), 0, v0 as vmv.v.x (#136010)\n\nThis extends the DAG combine introduced in 336b2909 to handle the case\nwhere the prior value is defined by a vmv.s.x instead of a vmv.v.x. If\nthe vrgather splats the single source element, and has no passthru we\ncan replace it with a vmv.v.x - which will in turn usually get folded\ninto a vmerge if a select follows.",
