/*
We test whether we can define symbols in a linker script and have them exported
to the output file symbol table.

This test uses a single X86-64 input object, simple.o, created with the
following X86-64 assembly code:

*** simple.S:

(command line clang -c simple.S -o simple.o)

      .text
      main:
        mov $1, %eax
        movq $1, %rdi
        movq $msg, %rsi
        movq $14, %rdx
        syscall
        ret

        .globl _start
      _start:
        call  main
        mov $60, %eax
        syscall
        ret

      .data
      msg: .asciz "Hello, World!\n"


We use the following linker script for this test:
