Allow generic foreign functions. Generic extern functions written in Rust have their names mangled, as well as their internal clownshoe __rust_abi functions. This allows e.g. specific monomorphizations of these functions to be used as callbacks. Closes #12502. 2014-08-01 23:25:41 -05:00			`fn foo<T>(); //~ ERROR foreign items may not have type parameters`

Forbid use of generics with foreign functions. Closes #10353. 2014-02-16 23:52:11 -06:00
