//! Test for inner statics with the same name. //! //! Before, the path name for all items defined in methods of traits and impls never //! took into account the name of the method. This meant that if you had two statics //! of the same name in two different methods the statics would end up having the //! same symbol named (even after mangling) because the path components leading to //! the symbol were exactly the same (just __extensions__ and the static name). //! //! It turns out that if you add the symbol "A" twice to LLVM, it automatically //! makes the second one "A1" instead of "A". What this meant is that in local crate //! compilations we never found this bug. Even across crates, this was never a //! problem. The problem arises when you have generic methods that don't get //! generated at compile-time of a library. If the statics were re-added to LLVM by //! a client crate of a library in a different order, you would reference different //! constants (the integer suffixes wouldn't be guaranteed to be the same). //@ run-pass //@ aux-build:inner_static.rs extern crate inner_static; pub fn main() { let a = inner_static::A::<()> { v: () }; let b = inner_static::B::<()> { v: () }; let c = inner_static::test::A::<()> { v: () }; assert_eq!(a.bar(), 2); assert_eq!(b.bar(), 4); assert_eq!(c.bar(), 6); }
