How to restart QEMU user mode programs from the GD

问题:

How to single step ARM assembler in GDB on Qemu? teaches us about QEMU user mode GDB step debugging and How do you start running the program over again in gdb with 'target remote'? teaches us that --multi allows you to re-run a program from inside GDB directly with run.

Does the QEMU user mode GDB stub, e.g. -g 1234 implement such --multi-like functionality, so I can run the program from inside gdb multiple times and keep my breakpoints around?

回答1:

QEMU doesn't implement this, I'm afraid. If you want to restart the guest binary you need to restart the gdb session too.
