The callee may set a field in st_other to 1 to indicate r2 should be treated as caller-saved. This means a trampoline must be used to save the current TOC before calling it and restore it afterwards, much like external calls.The 'callee', what is that here in that context ? Don't you mean the 'linker' instead ?
Callee in the sense of the function body, as opposed to the call-site like the R_PPC64_REL24, etc., relocations are (which I was thinking of as the caller). I can see how the comment needs more context though.
