Normally, the linker, ld.  It does then when it links the program.

The linker is part of the GNU binutils.

Note that on GNU/Linux the loader is a different program, also called
the dynamic linker, ld.so.  If the address to be pushed is in a shared
library, then the dynamic linker will compute the address at program
startup time.
