From: Enes Cevik <[email protected]>
This patch introduces the `exchange_malloc` lang item to compiler.
This lang item is a strict prerequisite for the `owned_box` lang item
and box expressions.
gcc/rust/ChangeLog:
* util/rust-lang-item.cc (Rust::LangItem::lang_items): Register
exchange_malloc to BiMap.
* util/rust-lang-item.h (LangItem::Kind): Add EXCHANGE_MALLOC.
gcc/testsuite/ChangeLog:
* rust/compile/exchange_malloc.rs: New test.
