// `-Z packed_bundled_libs` is an unstable rustc flag that makes the compiler
|

|
|
// only require a native library and no supplementary object files to compile.
|

|
|
// #105601 made it possible to have this behaviour without an unstable flag by
|
||
|
|
// passing +bundle in modifiers, and this test checks that this feature successfully
|
||
|
|
// compiles and includes only the static libraries, with no object files.
