What is the gcc equivalent option for the -qfuncsect option of XL compiler of AIX?

XL Compiler of AIX seems to have the -qfuncsect option which places each function in a seperate object control section with the effect that when the final executab开发者_运维技巧le is created it helps in removing unwanted functions.

Is there an equivalent option for the same in gcc? I am unable to find the same.
