• Check if it is possible to automatize GDB/LLDB executions to run then in CI

Yes, it is. Both tools have a batch mode, and we can pass a list of commands on a file to be executed by GDB/LLDB.
#851 and runtimeverification/k#3687 introduce the interface to enable GDB/LLDB executions in CI

• What do we want to test? Which programs and commands do we want to verify?

• k start, k step, k step n, quit
• Breakpoints
• k match rule (success and fail)
• print data types

• How to create a standard output between systems that don't contain any source directory or platform-specific info? We need to pipe all outputs to this standard format.
• Create the Debugger Test directory containing each test in a subfolder. Each test should contain:
  • The test file
  • A possible input
  • The debugger commands in a file
  • The expected output
• Integrate the test-suite with lit
