How to set the O0 compiler option?

(1/1)

I am using Valgrind to find the cause of a Segmentation Fault. On this webpage: http://valgrind.org/docs/manual/quick-start.html I see:

--- Quote ---Using -O0 is also a good idea, if you can tolerate the slowdown.

In Code:Blocks Settings => Compiler I see optimization flags for -O, -O1, -O2, -O3, and -Os . But I do not see -O0. How can the -O0 compiler option be put into effect?

blauzahn:
you can add it under "other compiler options".

I recommend to set these within the project's compiler settings instead of the general ones unless
you want to apply them to all your projects.

raynebc:
Isn't no optimization the default as long as you don't enable any optimization flags?

It depends on what the default is for the compiler.
