Re: [avr-gcc-list] regression in size from 4.2.2 to 4.5.0

for any of us to help

You must provide the options you used to compile.

provided compilable code snippets with the exact command line options  
you used.

it would be great if you made a makefile that ran the tests too.


-Os between the GCC versions most likely don't have the same options,  
i forget how to tell though...
