// 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
