[Bug target/40483] gcc 4.x needs to utilize better COMDAT mechanism under Solaris

["ro at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #1 from ro at gcc dot gnu dot org  2010-04-28 19:15 -------
One part of this PR (supporting COMDAT group on Solaris 2 with GNU as) is
implemented by this patch:

  [build, doc] Support COMDAT group with recent Sun ld
  http://gcc.gnu.org/ml/gcc-patches/2010-03/msg01482.html

which went into 4.5.0.  It requires snv_130, though, a recent OpenSolaris
build.
Unless paying customers require a backport from Oracle, this won't get into
earlier releases,though.

On the other hand, supporting COMDAT group with Sun as is still in the works.
I've made some progress with help from the Sun assembler and linker
maintainers,,
but still hit some issues in both as and ld.  I expect to have this ready for
4.6.0, but am undecided about a backport to the 4.5 branch yet.
