Hi,

Does gcc toochain have "unreferenced functions(not unused virtual
functions) removal" feature?(any options etc)
It seems like if gcc toolchain provides this feature, oversized C++ code
could be reduced.
In my case, due to the link of unnecessary functions, C++ executable image
is oversized. It looks like this problem is partially resolved if class is redefined and big object codes are divided to smaller ones.

Thanks,
