- Subject: debugging quality and gcc
Hi
I am wondering if from a developer perspective some body can tell
me what debugging quality to expect when using -g with O3.
Especially when the following happen
1. When a variable resides in multiple locations in different scopes
such as different registers.
If this works very well, I am wondering how gcc accomplishes this?
2. A function is inlined.
3. Constant propagation.
Due to constraints of my use, I have to generate code without the
frame pointer.
thanks
