           Summary: g++.dg/torture/stackalign/throw-1.C fails to compile
                    on IA64
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Keywords: link-failure
          Severity: normal
          Priority: P3
         Component: middle-end
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: sje@cup.hp.com
              Host: ia64-*-*
            Target: ia64-*-*
             Build: ia64-*-*


I am not sure exactly where this is going wrong but when
g++.dg/torture/stackalign/throw-1.C is compiled with -O3 -funroll-loops on IA64
I get an undefined label.

Here is a cutdown test case based on that test:

int global, global2;
int main()
{
        int i,j,k,l,m,n;
   for (i=0; i < global; i++)
   for (k=0; k < j; k++)
   for (l=0; l < k; l++)
   for (m=0; m < l; m++)
       global2 = k;
 throw 0;
}

When I compile it I get:

g++ -O3 -funroll-loops x.C
/tmp/ccVWUtRi.o: In function `main':
x.C:(.text+0xc2): undefined reference to `.L34'
collect2: ld returned 1 exit status
