The new option `--group-bytes` will provide the functionality to group multiple octets as a unit, which means that several bytes will be shown together without whitespace. It is quite similar...

It is basically the same as `-groupsize` in `xxd`. Since I didn't aware of the requirement of compatibility, so the naming didn't align with `xxd` at that time. I think...

For the part of the instruction cache, it can really help a lot for system emulators. In my experience, I have [icache.c](https://github.com/RinHizakura/riscv-emulator/blob/main/src/icache.c) on my risc-v emulator, and it improves performance...

I have checked those commits and also applied them to execute for testing. To my knowledge, they could work as same as the codes we used before. The duplicates of...

I make a change according to the comment, but please let me know if this is what you want. Thanks!

We can start by the formatting and compilation. Even with that coverage only, it's still good. For the functionality test of gdbstub, I plan to fork a simple and reliable...

Thanks to @fabiomurer 's contribution, now we have basic automated testing. Right now, I plan to maintain a few simple programs like [test.c](https://github.com/RinHizakura/mini-gdbstub/blob/main/tests/test.c), and then fill in the unsupported instructions...

Instead of using the condition variable. I'm considering whether [`epoll`](https://man7.org/linux/man-pages/man7/epoll.7.html) can be a better way to fix. We'll need to explore more.

I agree. Actually, we have a format check CI/CD now, so it won't be a strong requirement to install the git hook.
