Tsirkin RH-Acked-by: Miroslav Rezanina From: Janosch Frank This commit does not make the script python 3 compatible, it is a preparation that fixes the easy and common incompatibilities. Print is a function in python 3 and therefore needs braces around its arguments. Range does not cast a gdb.Value object to int in python 3, we have to do it ourselves.
