Research direction
The linked files pwndbg/lib/abi.py and pwndbg/aglib/disasm/arch.py need to be modified. First, wait for pwntools PR #2529 to be merged. Then implement ABI code for LoongArch64 and s390x in abi.py, and add syscall names for both architectures in arch.py. The existing patterns for other architectures like RISC V can serve as reference.
