I noticed that the .vx RVV instructions refer to the GPR source as both xs1 and rs1:

riscv-unified-db/arch/inst/V/vadd.vx.yaml

Lines 10 to 18 in 1c982a4

assembly: vd, vs2, xs1, vm
encoding:
match: 000000-----------100-----1010111
variables:
- name: vm
location: 25-25
- name: vs2
location: 24-20
- name: rs1

This might be fine and don't look wrong on the produced artifacts, but I'm not sure it's intended.
