            Bug ID: 18554
           Summary: ARM: debuginfo for tls variable contains wrong
                    relocation
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: Backend: ARM
          Assignee: unassignedbugs at nondot.org

If you compile the following C program with debug info (-g)

__thread int x;

then gcc 4.8 generates in section .debug_info

    .word x(tlsldo)

but clang/LLVM generates

    .long x

This results in an error during link time. (All ARMv7.)

Found while porting LDC to the ARM platform.
