           Summary: gccld crashes when linking my compiled Cool program
           Product: tools
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gccld
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: bocchino at uiuc.edu


I attempted to link a program compiled to LLVM with my Cool compiler (written
for CS 326).  When I did this, I got a Verify error stating that an instruction
did not dominate all uses.  The program works when linked by hand (copying the
two files into one) and when linked with llvm-link, so there appears to be a bug
in gccld.  I ran bugpoint on the linked program and narrowed the problem down to
running opt -simplifycfg on the reduced function.
