// This test checks the compatibility of the interaction between `--emit obj` and
|
|
// `#[global_allocator]`, as it is now possible to invoke the latter without the
|
|
// allocator shim since #86844. As this feature is unstable, it should fail if
|
|
// --cfg check_feature_gate is passed.
|
|
// See https://github.com/rust-lang/rust/pull/86844

|
//@ ignore-cross-compile
|
|
// Reason: the compiled binary is executed

//@ ignore-msvc

//FIXME(Oneirical): Getting this to work on MSVC requires passing libcmt.lib to CC,
|
|
// which is not trivial to do.
