Oh, interesting! I can't recreate that behavior by manually setting large offsets in this test. What assembly did you use to expose that?

We do use this codepath for adrp, but I guess only on Windows. `case AArch64::fixup_aarch64_pcrel_adrp_imm21` handles the fixup, and it's tested in `llvm/test/MC/AArch64/fixup-out-of-range.s`.
