           Summary: bad assembly output breakes llvm-gcc bootstrap
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Backend: X86
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: rafael.espindola at gmail.com
                CC: llvmbugs at cs.uiuc.edu


The llvm-gcc bootstrap is broken because llvm is producing an output that gas
doesn't like. With the attached test:

llc test.bc -march=x86-64  -o -| as
{standard input}: Assembler messages:
{standard input}:1039: Error: suffix or operands invalid for `mov'

Line 1039 is

        movb    %eax, %c
