gcc/rust/ChangeLog:
* typecheck/rust-hir-type-check-stmt.cc (TypeCheckStmt::visit): Turn
constant item typechecking into a coercion site instead of a unify
site.
gcc/testsuite/ChangeLog:
* rust/compile/const6.rs: New test.
Signed-off-by: Faisal Abbas <90.abbasfaisal@gmail.com>
Tested on x86_64-pc-linux-gnu, committed on master.
