// There are 3 cases today (as paraphrased from the ELFv2 document):
//
//  1. R2 holds the TOC pointer on entry. The call stub must save R2 into the ELFv2 TOC stack save slot.
//
//  2. R2 holds the TOC pointer on entry. The caller has already saved R2 to the TOC stack save slot.
//
//  3. R2 does not hold the TOC pointer on entry. The caller has no expectations of R2.
