Summary: This directive is used for setting up $gp in the beginning of a function. It expands to three instructions if PIC is enabled: lui $gp, %hi(_gp_disp) addui $gp, $gp, %lo(_gp_disp) addu $gp, $gp, $reg _gp_disp is a special symbol that the linker sets to the distance between the lui instruction and the context pointer (_gp).
