// The `#[link(cfg(..))]` annotation means that the `#[link]`
// directive is only active in a compilation unit if that `cfg` value is satisfied.
// For example, when compiling an rlib, these directives are just encoded and
// ignored for dylibs, and all staticlibs are continued to be put into the rlib as
// usual. When placing that rlib into a staticlib, executable, or dylib, however,
// the `cfg` is evaluated *as if it were defined in the final artifact* and the
// library is decided to be linked or not.
// This test exercises this new feature by testing it with no dependencies, then
// with only dynamic libraries, then with both a staticlib and dylibs. Compilation
// and execution should be successful.
// See https://github.com/rust-lang/rust/pull/37545
//@ ignore-cross-compile
// Reason: the compiled binary is executed
