Function Level linking in gcc

I search in old t开发者_开发问答hreads. But didn't find any thread answering my question.

Is gcc support function level linking like vc++ ?

if yes what option should I give to link object files and library ?

Looks like gcc does not support function level linking directly. You can pass -ffunction-sections -fdata-sections command line options to reduce resulting executable size. Look also this link for more info.
