## References to this generate a section relocation
## N.B.: ld64 doesn't actually reorder symbols in __cstring based on the order
##       file. Only our implementation does. However, I'm not sure how else to
##       test section relocations that target an address inside a relocated
##       symbol: using a non-__cstring section would cause llvm-mc to emit a
##       symbol relocation instead using the nearest symbol.

  .asciz "Private symbol"
