--- 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. -- ro at gcc dot gnu dot org changed: What|Removed |Added AssignedTo|unassigned at gcc dot gnu |ro at gcc dot gnu dot org |dot org | Status|UNCONFIRMED |ASSIGNED Ever Confirmed|0 |1 GCC target triplet|i386-solaris|*-*-solaris2* Last reconfirmed|-00-00 00:00:00 |2010-04-28 19:15:45 date|| http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40483
