I was wondering if AArch64 doesn't use `DT_FINI` by default and you have to work around this in BOLT by forcing the linker to emit it through `-fini` or something similar. That's the case for RISC-V (it only use `DT_FINI_ARRAY` by default) so that's why I created the patch I talked about before. But maybe we should continue this discussion once I post that patch :)
