This doc lists all significant deliberate differences in behavior between LD64 and LLD-MachO.

String Literal Deduplication

LD64 always deduplicates string literals. LLD only does it when the `--icf=` or
the `--deduplicate-literals` flag is passed. Omitting deduplication by default

equality must be fixed to use value equality instead.

- LLD
* This turns off ICF and string merging in the linker.
