Omitting heaptrc should be -gh- or just -g- for all debug stuff off.
Well, it should just be NOT giving -gh
But if it is anywhere a -g- LATER in the command line takes it off again
You can do
-g- -gw -gl if you want to add line info
I guess I don't need to telly you, if you want max performance
No -Criot orthe like
instead
-Cr- -Ci- -Co- -Ct-
-Sa- no assert
-Si inline
-O3 optimize, though -O2 will be good enough, and may take slightly less time to compile the IDE
