stupid linker question.... to remove unused functions in the object file.
Hi, I have few functions in a C file but those are not called at present. Even though those function definitions are part of the object file. Those will be called later on. What CFLAGS should I pass to remove unused functions? I cannot enable -Ox at present to have any unpredictable behaviour.

I believe you can use -ffunction-sections -Wl,--gc-sections when you compile and link. If you have binutils prior to 2.16, this only works with -static. -B On Jul 24, 2006, at 7:07 AM, Parav Pandit wrote: Hi, I have few functions in a C file but those are not called at present.
