ELF] Remove merge strings functionality.

Authored by shankare on Sep 26 2015, 4:20 PM.



The reader creates mergeable strings for sections that have the flag SHF_MERGE|SHF_STRINGS set, Lets delay string merging until the output fie is being written to disk.

The time will also be saved because the reader may try to atomize a section
that is has been garbage collected containing strings very early when garbage
collection is enabled.

Many people are actively working on elf2 implementation now. This patch seems to remove an existing feature from the existing implementation and add no new features. I doubt that it's worth taking the risk of regressions.

merge strings has bugs that will eventually crash applications built using this switch. I will add a proper implementation soon.

Any other comments ?, If not I will go ahead and commit this change and continue getting the Atom model for ELF

Looks like patch was not committed. May be it obsolete?
