Obviously, the option --freedback for armcc doesn't work. But setting -flto to compiler controls or linker controls (or checking the Link-time optimization checkbox) shows this error:
error: use of LTO is disallowed in this variant of ARM Compiler
And that seems strange since this article is dated 2015 - community.arm.com/.../link-time-optimization-in-arm-compiler-6 - and I'm using Keil 5.24.1 two years later.
Is there another way to do it?
So which variant, exactly, is that?
Is it one of the Lite or STM32F0/L0 free versions?
It's ARM MDK-Lite Version: 5.24.1 according to the about panel.
That probably answers the question, then?
Are you asking or telling?
Does it? Armcc in lite version could remove unused functions. Is there some kind of list of options that are not available on lite version now?

Or contact Keil direct; remember - the forum is not an official support channel.
-flto is not mentioned in this list, so I don't understand why are you so sure about that.
If you want a definitive answer - rather than just some ignorant user - contact Keil direct.
Fair enough.
