Working with the Freescale S08 and S12 build tools, there is something I really appreciated: that the linker reports on the console the code size of the application:
This is especially handy as it allows you to see the impact on code size immediately e.g. if I change a compiler option or do a source code change. Simple and easy. Yes, I could get that kind of information from the linker map file too. But this means I need to open that file, scroll down/etc: many steps just to find out the code size.
