           Summary: Several C++ LTO testcases fail to link on IRIX 6.5
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Keywords: link-failure, lto
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ro@gcc.gnu.org
              Host: mips-sgi-irix6.5
            Target: mips-sgi-irix6.5
             Build: mips-sgi-irix6.5


Several C++ testcases fail to link on IRIX 6.5 with LTO, e.g.

FAIL: g++.dg/lto/20081109 cp_lto_20081109_0.o-cp_lto_20081109_1.o link, -O0
-flto -flto-partition=none 
UNRESOLVED: g++.dg/lto/20081109 cp_lto_20081109_0.o-cp_lto_20081109_1.o execute
-O0 -flto -flto-partition=none 


ld32: ERROR   33 : Unresolved data symbol ".LDFCM0" -- 1st referenced by
/var/tmp//cc5OGg5s.lto.o.

    Use linker option -v to see when and which objects, archives and dsos are
loaded.  

ld32: ERROR   33 : Unresolved data symbol ".LDFCM1" -- 1st referenced by
/var/tmp//cc5OGg5s.lto.o.

    Use linker option -v to see when and which objects, archives and dsos are
loaded.  

ld32: INFO    152: Output file removed because of error.

collect2: ld returned 2 exit status


It turned out that those missing symbols are created by lto1: this invocation
reproduces the problem:

$ lto1 -quiet -mabi=n32 -O0 -flto-partition=none cp_lto_20081109_0.o -o
cp_lto_20081109_0.s

It turns out that there are references to .LDFCM[01], but only
.LDFCM[01].124[45]
are defined.

.LDFCM[01].124[45]

are "localized" symbols.  If references to the original symbols remain it
means that those are not properly connected.

Btw, I remember seeing similar issues when testing libstdc++ on x86_64-linux
with -flto.

Is this fixed with http://gcc.gnu.org/ml/gcc-patches/2010-12/msg00081.html
(already comitted)?
It seems like the same issue.

Yes, the failure is gone.

Thanks.
