That makes sense to me. (In reply to Jidong Xiao from comment #4) > Jatin, are you using gdb to do the single step?(In reply to Jatin Kumar from > comment #2) No. I have been doing single stepping from inside the OS. It single steps its own code using debug trap untill some condition is met. During this whenever I hit an out instruction, the very next instruction is not skipped while single stepping. It may have been executing it because overall the code seems to be working correctly. I couldn't find anything online in this regard so I am curious if this is something QEMU specific. -- You are receiving this mail because: You are watching the assignee of the bug.
