I had send gcc and binutils patch to mainlist . But I only support them
in newlib , not in glibc and qemu. As I know, qemu not support this now.

I would suggest you could send all necessary parts like binutils,
glibc and/or qemu together future, so that we could easier test that?

This patch support rv64 insn in ilp32 ABI. It was inspired by aarch64
both
support 64-bit and 32-bit ABI with the same set of instructions.
gcc/ChangeLog:
* config.gcc: Implememt ilp32* with rv64*.
* config/riscv/riscv.cc (riscv_option_override): Remove the
constraint between RV64 and ILP32.
* config/riscv/riscv.h (TARGET_ILP32): Define TARGET_ILP32 with
riscv_abi.
(POINTER_SIZE):POINTER_SIZE will change with TARGET_ILP32.
(Pmode):Likewise.
* config/riscv/riscv.md: Convert split mode with Pmode and change
mode form Xmode to Pmode in stack_tie.
This is a new feature and thus I think we should defer to gcc-14 unless
there is a compelling need.
I agree. This is a pretty big one with a lot of ABI-related
complications, so let's just play it safe.
