I've noticed that lld keeps the data section more isolated than the gold or bfd linkers. For example, readelf -l applied to the "same" executable linked with those three linkers reveals the following under "Section to Segment mapping":<br>

This separation seems to result in lld creating two LOAD RW segments whenever gold or bfd would create only one. For example, also from readelf -l output:<br>

Could someone explain why the lld behavior is different? Is there a way to make it match the gold/bfd behavior? I've looked through the options list and read some of the lld code, but so far have not been able to find a solution.<br>
