Re: [avr-gcc-list] How to set section order

In the source code, the smaller function comes after but is located before in the .lss file.
With optimization -O0, it's correctly located after.
I attached the source code and the makefile (generated by avrstudio) I use if it can be of any help.
Thanks

Yes. I noticed that without optimization, the linker keep the order the functions appear in the code but if I turn on optimization (-Os) then the smaller function comes first.

Hmm. That seems contradictory to me, so I must not be understanding you correctly.

Yes, the smaller function comes first in your *source code*? Or, no, it comes after the bootloader.

In my experience, the compiler keeps the order, no matter what the optimization. But this could be something new.
