如何将IDA界面显示的指令从ARM架构切换为X86架构

Got it, let's walk through the common ways to switch over to x86/x86-64 assembly instructions, depending on what tool you're working with:

Compiler (GCC/Clang) #

If you're generating assembly from source code, you just need to tell the compiler to target x86/x86-64 instead of ARM:

• For x86-64 (64-bit, uses movq, cmpq): Use the -m64 flag. Example:

  gcc -m64 -S your_program.c
  

  The output your_program.s file will have x86-64 assembly instructions.
• For 32-bit x86 (uses movl, addl): Replace -m64 with -m32.
• If you're on an ARM machine, you'll need the x86 cross-compiler first. On Debian/Ubuntu, install it with:

  sudo apt install gcc-x86-64-linux-gnu
  

  Then compile using the cross-compiler binary:

  x86_64-linux-gnu-gcc -S your_program.c
  

Disassemblers (objdump, GDB) #

If you're examining existing binaries, explicitly tell the disassembler to use the x86 architecture:

• objdump: Add the -M x86-64 flag for 64-bit, or -M i386 for 32-bit. Example:

  objdump -d -M x86-64 your_binary_file
  

• GDB: Once inside GDB, set the target architecture first before disassembling:

  set architecture i386:x86-64
  disassemble main
  

  This will render x86-64 instructions instead of ARM.

Online Assembly/Disassembly Tools #

If you're using web-based tools, look for an architecture dropdown menu and select x86 or x86-64 (sometimes labeled as AMD64). Most tools let you switch this setting before generating or disassembling code.
