  • Using raw values for opcode fields is concise but less readable; using named constants (MASK/MATCH) improves readability at the cost of slightly more verbose definitions.

Re: [PATCH v3 01/13] RISC-V: add dedicated vector arithmetic .insn forms

A reviewer has provided a positive ‘Looks Good To Me’ (LGTM) on a patch series introducing dedicated .insn forms for RISC-V vector arithmetic instructions. While the patch is considered good enough to merge, the reviewer suggests a minor improvement: defining separate masks and matches for the funct3 field instead of using raw hexadecimal values (0x7000), which would enhance code readability and understanding.
