[arm-gnu] Image size reduction with linker optimization

["Michael Downing" <Michael_Downing@xxxxxxxxxxx>]

I am developing a program using CodeSourcery Lite and the ST drivers for
the STM32 family.  I am calling only a few functions in the ST driver
files, and yet I see ALL of the functions of those files included,
whether they are called or not.  I want to minimize my image size by
getting rid of this unused code.

 

When I compile and link using the Raisonance toolkit (also gnu), I don't
see this extraneous code linked in.

 

I've tried all the reasonable linker options I can find in the
documentation, with no luck.  

 

Any suggestions?

 

TIA,
