From: Pierre-Emmanuel Patry <[email protected]>
Top level module should collide with extern crate names and the error
should be reported on the module, not the extern crate because the latter
may not have a source location given it may have been injected.
gcc/testsuite/ChangeLog:
* rust/minicore/top_core_modules.rs: New test.
* rust/minicore/top_core_modules_core/lib.rs: New test.
Signed-off-by: Pierre-Emmanuel Patry <[email protected]>
Tested on x86_64-pc-linux-gnu.
