| // and we shouldn't have null pointer dereferences in these helpers. |
| // * LLVM doesn't want to inline functions with different list of builtins. C |
| // side has `-fno-builtin-wcslen`; `wcslen` is not a Rust builtin, so they |
| // should be compatible, but LLVM does not perform inlining due to attributes |
| // mismatch. |

| // complain if `-Ctarget-feature=+cmov,+cx8,+fxsr` is used). x86-64 always |
