Notation: dst is `t->getThunkTargetSym()->getVA()` On AArch64, when `src-0x8000000-r_addend <= dst < src-0x8000000`, the condition `target->inBranchRange(rel.type, src, rel.sym->getVA(rel.addend))` may incorrectly consider a thunk reusable. `rel.addend = -getPCBias(rel.type)` resets the addend to 0 for AArch64/PPC and the zero addend is used by `rel.sym->getVA(rel.addend)` to check out-of-range relocations. See the test for a case this computation is wrong: `error: a.o:(.text_high+0x4): relocation R_AARCH64_JUMP26 out of range: -134217732 is not in [-134217728, 134217727]` I have seen a real world case with r_addend=19960.
