Removing unused code fror NIOS target

Hi All, 

 

I am using nios-elf tools to compile and build a binary for NIOS target. There are many  

unused functions in the code which I want to remove during linking. 

I have used -ffunction-sections as a compile option and -gc-sections as linker option. Though I am able to put the functions in their own sections , I am not able to run the resulting binary. 

I have often read that not all targets support this. Does any one know if NIOS target supports this? 

 

Cheers, 

Ajay

Did you try putting each function in a separate file, creating a library out of them, and linking the library to the main file? the linker should be able to do the job automatically for you!
