[lldb-dev] [RFC] OS Awareness in LLDB

[Alexander Polyakov via lldb-dev]

Hi Leonard,

I think it will be kernel-mode debugging since debugging an application in
user mode is not an OS awareness imo. Of course, some of kernel's modules
might run in user-mode, but it will be ok I think.

Thanks for your reference, I'll take a look at it.

Also, I found out that ARM supports OS awareness in their DS-5 debugger.
They have a mechanism for adding new operating systems. All you need to do
is to describe OS' model (thread's or task's structure for example). I
think that is how it might be done in LLDB.
