Technical tradeoffs
- • Potential ambiguity with future OP_VE instructions if naming conventions are not carefully considered.
- • The current parsing logic may not support both signed and unsigned immediates for OPIVI instructions.
- • Adding forms with immediates for V*UNARY* instructions could increase code complexity.

[PATCH v2 03/16] RISC-V: add dedicated vector arithmetic .insn forms
This patch adds dedicated .insn forms for RISC-V vector arithmetic instructions, aiming to make assembly code easier to write and read. The patch introduces new forms for the OP_V opcode. The author is seeking feedback on naming conventions for future OP_VE instructions and on the possibility of adding forms with immediates for encoding VUNARY instructions.
