// 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.

//FIXME(Oneirical): Getting this to work on MSVC requires passing libcmt.lib to CC,
