[PATCH] Bug 12843: put ELF reloc section against section with template function instantiation in the same COMDAT group

[Tim Northover]

Hi Igor,

Hmm. As far as I can see the ELF specification is unclear on the
correct behaviour here. We currently seem to match GCC behaviour,
which does not put the relocation sections into the COMDAT groups
explicitly.

Much as I prefer these things to be explicit, it almost seems more
consistent with the rest of ELF that relocation sections aren't
included in COMDAT. Otherwise, shouldn't we be creating group sections
for every .section/.rel.section pair? It looks like they have the same
semantics.

Cheers.

Tim.
