描述

Currently pwntools does not support parsing coredumps that are from MIPS binaries. Would be nice if it did.

FYI: The current list of architectures supported: pwntools/pwnlib/elf/corefile.py:102

prstatus_types = {
    'i386': elf_prstatus_i386,
    'amd64': elf_prstatus_amd64,
    'arm': elf_prstatus_arm,
    'aarch64': elf_prstatus_aarch64
}

研究方向
First, examine the existing prstatus types dictionary in pwntools/pwnlib/elf/corefile.py around line 102 to understand the structure definitions for supported architectures (i386, amd64, arm, aarch64). Then, research the MIPS ELF core file format to define the appropriate prstatus structure for MIPS (both 32 bit and 64 bit variants if applicable). Implement the new entry in the dictionary and add corresponding constants if needed. Finally, test the implementation using a MIPS coredump from a known binary to ensure parsing works correctly. The comment on the issue may contain additional context.
