## 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.
