This patch is support zfinx extension on binutils, zfinx is not compatible with any float extension and use gpr replace fpr, we adjust the opreand set when zfinx used. For disassemble part, we add a flag ZFINX(0x10) as ELF-header to distinguish whether use gpr or fpr name for float instructions.
jiawei (3):
RISC-V: Add mininal support for z[fdq]inx
RISC-V: Add instructions and operand set for z[fdq]inx
RISC-V: Add testcases and disassemble support for z[fdq]inx

But we need to add a new operand 'x', and add multiple extra entries of riscv_opcodes. Jim has suggested before, and after discussing with Kito, I think the better solution should be as follows: * Just change the zfinx instructions from INSN_CLASS_F to INSN_CLASS_ZFINX class (or probably INSN_CLASS_F_OR_ZFINX), but keep the original operands.

I have sent a patch to let dis-assembler can access the elf attributes, and then parse the architecture string: https://sourceware.org/pipermail/binutils/2021-November/118444.html So that you can call "riscv_subset_supports (&riscv_rps_dis, "zfinx")" to check if the zfinx extension is enable or not, and without adding and checking the new elf header flag. I will commit my patch in a few days, so please feel free to contact me if you have any questions.
