[lldb] [Process/NetBSD] Set xs_xstate_bv correctly when setting regs

Authored by mgorny on Oct 24 2020, 2:42 PM.



Ensure that xs_xstate_bv is set correctly before calling
WriteRegisterSet(). The bit can be clear if the relevant registers
were at their initial state when they were read, and it needs to be set
in order to apply changes from the XState structure.

Hmm, I have an idea how to avoid all this repetition.

Reduce the repetition by bringing the most common case out.

Linux has this factored into a separate function (UpdateXSTATEforWrite), but this isn't too bad either. Could be another candidate for factoring...
