I would like to add 3 more commands to GDB, *set, unset, list PCB *commands
and would like to break if I have the same value with the *program context
register(special register implemented by me). *How can I implement these
commands? Where can I start from?
Kind regards,
Nagmat

Hi Nagmat,
Maybe I don't understand your goal correctly, but it sounds like you could use breakpoints conditions?

Hi Nagmat,
Please keep the list in CC when participating in a discussion on a
mailing list.
The commands are added in the _initialize_* functions in various files.
For example, here's where the "break" command is created:
https://sourceware.org/git/?p=binutils-gdb.git;a=blob;f=gdb/breakpoint.c;h=23278320d9d465943bf94ec2c35a5a1438c45f2a;hb=b74dbc2093191b10f4963f43ee570b54c9593404#l15802
