RE: [PATCH 0/5] RISC-V: Support vf and vx for autovec comparison of

[Demin Han]

Sorry for the unexpected truncation.

Hi,
vf and vx are not supported well when comparing vector and
immediate in current autovec.
For example, following insts generated for float type:
    flw
    vsetvli
    vfmv.v.f
    ...
    vmfxx.vv
Two issues:
  1. Additional vsetvl and vfmv instructions
  2. Occupy one vector register and may results in smaller lmul

We expect:
    flw
    ...
    vmfxx.vf

For simplicity of supporting vx and vf, two refactors completed first.
1. remove eqne pattern; any special case or reason for eqne when first added?
2. refactor duplicate code.
