Re: Is there a way to check values of registers before and after running a program on qemu-system-risc64v?

Yes, the si command is more helpful than continue.

Thank you for the suggestion.

Why are you even creating 4 cpus (I saw that you had this option `-smp 4`)
Just have 1 cpu. You could use the gdb command `si` (step into)
instead of continuing.
Practically you will be stepping through 5 or 6 instructions.

As a side note, you may be just starting these things and thus getting
introduced to a lot of
sw / tools (like qemu, gdb, compiler) and it might be overwhelming.
But I would advise that
spend time with them and their documentation / internet search. What
do they do and why
do they do it? It'll help you understand and validate your own thought
process and make you
figure out things on your own.
