// The helper functions are all inline functions.
//
// We use `__always_inline` here to bypass LLVM inlining checks, in case the
// helpers are inlined directly into Rust CGUs.
//
// The LLVM inlining checks are false positives:
// * LLVM doesn't want to inline functions compiled with
// `-fno-delete-null-pointer-checks` with code compiled without.
// The C CGUs all have this enabled and Rust CGUs don't. Inlining is okay
// since this is one of the hardening features that does not change the ABI,
// 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.
// * clang and Rust doesn't have the exact target string. Clang generates
// `+cmov,+cx8,+fxsr` but Rust doesn't enable them (in fact, Rust will
// complain if `-Ctarget-feature=+cmov,+cx8,+fxsr` is used). x86-64 always
// enable these features, so they are in fact the same target string, but
// LLVM doesn't understand this and so inlining is inhibited. This can be
// bypassed with `--ignore-tti-inline-compatible`, but this is a hidden
// option.
