Jez Ng 525bfa10ec [lld-macho] Emit personalities in compact unwind ... Note that there is a triple indirection involved with personalities and compact unwind: 1. Two bits of each CU encoding are used as an offset into the personality array. 2. Each entry of the personality array is an offset from the image base. The resulting address (after adding the image base) should point within the GOT. 3. The corresponding GOT entry contains the actual pointer to the personality function. To further complicate things, when the personality function is in the object file (as opposed to a dylib), its references in `__compact_unwind` may refer to it via a section + offset relocation instead of a symbol relocation. Since our GOT implementation can only create entries for symbols, we have to create a synthetic symbol at the given section offset.
