- RISC-V `O4` operand descriptor renames to `O7` for clarity.
- tldr
- Binutils RISC-V assembler's `.insn` operand descriptor `O4` has been renamed to `O7` to accurately reflect its 7-bit field size, improving consistency.

The RISC-V assembler’s .insn directive previously used the O4 operand descriptor to represent a 7-bit field. This descriptor has been renamed to O7 to align with the field’s actual width, consistent with existing O<n> and F<n> descriptors that denote bit-field sizes. This change improves the clarity and long-term maintainability of the assembler’s operand handling.
