Errr, why you just mixed in JuZhe’s patch set into this patch set?

> Changes in v6:
> - Incorporated upstream comments, added target hook for
> TARGET_VECTORIZE_SUPPORT_VECTOR_MISALIGNMENT
>
> Changes in v5:
>
> - Incorporated upstream comments large to delete unnecessary code
>
> Changes in v4:
>
> - Added support for binary integer operations and test cases
> - Fixed bug to support 8-bit integer vectorization
> - Fixed several assert errors related to non-multiple of two vector modes
>
> Changes in v3:
>
> - Removed the cost model and cost hooks based on feedback from Richard
> Biener
> - Used RVV_VUNDEF macro to fix failing patterns
>
> Changes in v2
>
> - Updated ChangeLog entry to include RiVAI contributions
> - Fixed ChangeLog email formatting
> - Fixed gnu formatting issues in the code
