From bbbb571fee01532f63b105150654db8db0b01bf7 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Mon, 9 Feb 2015 16:33:19 -0800 Subject: rustc: Fix a number of stability lint holes There are a number of holes that the stability lint did not previously cover, including: * Types * Bounds on type parameters on functions and impls * Where clauses * Imports * Patterns (structs and enums) These holes have all been fixed by overriding the `visit_path` function on the AST visitor instead of a few specialized cases. This change also necessitated a few stability changes: * The `collections::fmt` module is now stable (it was already supposed to be). * The `thread_local::imp::Key` type is now stable (it was already supposed to be). * The `std::rt::{begin_unwind, begin_unwind_fmt}` functions are now stable. These are required via the `panic!` macro. * The `std::old_io::stdio::{println, println_args}` functions are now stable. These are required by the `print!` and `println!` macros. * The `ops::{FnOnce, FnMut, Fn}` traits are now `#[stable]`. This is required to make bounds with these traits stable. Note that manual implementations of these traits are still gated by default, this stability only allows bounds such as `F: FnOnce()`. Additionally, the compiler now has special logic to ignore its own generated `__test` module for the `--test` harness in terms of stability.
