Some people seem to prefer it. However I almost always use at least
-O2 for debug builds, otherwise the assembler code is basically unreadable.
Particularly -O0 is something I consider useless for debugging:
Often bugs will just disappear, and if anything is unclear and
you need to single-step through the asm code it is so huge and
convoluted you simply don't have the slightest chance to understand
