Good suggestions, David.
I remember that you reminded me about this issue before this time. But recently my email
system switched to Gmail, and made a mistake again. I'm trying to get used to the
Gmail
system.
But anyway, I hope that my last reply answered your questions.
Yes, thank you. But did you see my feedback about some of the error
output, when I tested your branch?
Do you have a list of existing issues?
I can fairly easily test your experimental branch on a series of
vmcores, if that helps.
Here's the feedback, cut/pasted from the other email thread:
I'm seeing a lot of "invalid input" displayed like the below when
using the 'bt' command. Is this a known issue?
bt: invalid input: "jne"
bt: invalid input: "mov"
bt: invalid input: "movl"
bt: invalid input: "jne"
bt: invalid input: "jne"
bt: invalid input: "jne"
bt: invalid input: "rep"
bt: invalid input: "je"
bt: invalid input: "je"
bt: invalid input: "je"
bt: invalid input: "call"
bt: invalid input: "call"
bt: invalid input: "jne"
