Rafael Espindola	4368bdb270	Make gc a bit more aggressive. We were not gcing any section whose name was a C identifier. Both gold and bfd only keep those if they are used. To avoid having to create the __start/__stop symbols early or doing string lookups in resolvedReloc, this patch just looks for undefined symbols __start/__stop to decide if a section is needed or not. llvm-svn: 296723	2017-03-02 01:50:34 +00:00

Make gc a bit more aggressive.

We were not gcing any section whose name was a C identifier. Both gold
and bfd only keep those if they are used.

To avoid having to create the __start/__stop symbols early or doing
string lookups in resolvedReloc, this patch just looks for undefined
symbols __start/__stop to decide if a section is needed or not.

[ELF] - Referencing __start or __stop should keep the section from GC.

This fixes the https://llvm.org/bugs/show_bug.cgi?id=22906 bug.

In GNU Binutils, a reference to start or stop is sufficient to 
prevent the section from being garbage collected.
Patch implements the same behavior for lld.
