           Summary: llvm-mc cannot parse gcc output
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Common Code Generator Code
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rafael.espindola at gmail.com
                CC: llvmbugs at cs.uiuc.edu


gcc 4.4.3 will compile

-------------------------------------
class ios_base   {
public: virtual ~ios_base();
};
class StrStream : virtual  public ios_base {
};
static void PrintTestPartResultToString() {
  new StrStream;
}
----------------------------------

into

.....
jmp    .LTHUNK0
.....
.set    .LTHUNK0,_ZN9StrStreamD1Ev

We currently reject that since we impose the semantics that a variable is
replaced base on what has been seen so far. It might be better to switch to a
full file semantics.
