Hi all:
My steps:
1. Attach to a running process, I've unchecked "tracking variables
and signals" in "Debugger -> Advanced" tab
2. I have Registers View/Variables View open
3. Set breakpoint
4. Debug step by step
What i see:
When a breakpoint is hit, CDT sends too much MI commands to GDB
(output is below)
It's already a performance killer, and it gets even worse if i turn
on "tracking variables and signals".
I have to wait for a long time during stepping.
Can i disable sending those commands during debugging? (Only send those
command when i click on Variables View/Registers View)
Regards
Xing Yun
