Note #1618 is the same but without a flag (I'm leaning towards that being better, but thought I'd leave it up to you) |
…d sections lld does this by default. See: https://crbug.com/529102889 This flag makes mold behave like lld when both --as-needed and --gc-sections are used. If a DSO is only referenced by sections that are garbage-collected, the DSO's DT_NEEDED entry will be omitted.
