I enabled the permanent single step mode (with the S+ command) and a permanent show the Thread Control Block (with the t+ command) option. So, I was able to single-step with "g" command. Also, I found "jr" (go until return (ret or iret) is encountered) and "jb" (go until the next branch instruction, like jmp/call/int) commands, but they don't seem to work. When I enter them, I see only a single step to the next instruction. Are these two commands broken? How do I step over a "call"/"int" instruction?
Fiasco/L4Env has been outdated for almost 10 years now and hasn’t been maintained since then. Sorry, but here we are unable to help you with your problem.
Are there any reasons you chose Fiasco/L4Env over Fiasco.OC/L4Re?
