The R_MIPS_GPREL16 / R_MIPS_GPREL32 relocations use the following expressions for calculations: ``` local symbol: S + A + GP0 - GP global symbol: S + A - GP GP - Represents the final gp value, i.e. _gp symbol GP0 - Represents the gp value used to create the relocatable object ``` The GP0 value is taken from the .reginfo data section defined by an object file. To implement that I keep a reference to `MipsReginfoInputSection` in the `ObjectFile` class. This reference is used by the `ObjectFile::getMipsGp0` method to return the GP0 value.
