           Summary: Integrated assembler doesn't resolve local symbol
                    differences
           Product: libraries
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Target Description Classes
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: joerg at NetBSD.org
                CC: llvmbugs at cs.uiuc.edu


OpenSSL's aes-x86_64.s does something like

        movq T-S, %rax

        .globl T
T:

        .globl S
S:

This results in a R_X86_64_PC32 text relocation, which GNU ld doesn't like.
Runnning the same code through GNU as doesn't result in a relocation, e.g. the
difference is handled internally. Same for using . in place of S.
