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.
