We only check the prefix is 'v', so that no extra attribute is needed. gcc/ChangeLog: * config/riscv/riscv-protos.h (riscv_asm_output_opcode): New function to add assembler insn code prefix/suffix. * config/riscv/riscv.cc (riscv_asm_output_opcode): Likewise. * config/riscv/riscv.h (ASM_OUTPUT_OPCODE): Likewise.
